  • Makefile issue with compiling a C++ program

    - by Steve
    I recently got MySQL compiled and working on Cygwin, and got a simple test example from online to verify that it worked. The test example compiled and ran successfully. However, when incorporating MySQL in a hobby project of mine it isn't compiling which I believe is due to how the Makefile is setup, I have no experience with Makefiles and after reading tutorials about them, I have a better grasp but still can't get it working correctly. When I try and compile my hobby project I recieve errors such as: Obj/Database.o:Database.cpp:(.text+0x492): undefined reference to `_mysql_insert_id' Obj/Database.o:Database.cpp:(.text+0x4c1): undefined reference to `_mysql_affected_rows' collect2: ld returned 1 exit status make[1]: *** [build] Error 1 make: *** [all] Error 2 Here is my Makefile, it worked with compiling and building the source before I attempted to put in MySQL support into the project. The LIBMYSQL paths are correct, verified by 'mysql_config'. COMPILER = g++ WARNING1 = -Wall -Werror -Wformat-security -Winline -Wshadow -Wpointer-arith WARNING2 = -Wcast-align -Wcast-qual -Wredundant-decls LIBMYSQL = -I/usr/local/include/mysql -L/usr/local/lib/mysql -lmysqlclient DEBUGGER = -g3 OPTIMISE = -O C_FLAGS = $(OPTIMISE) $(DEBUGGER) $(WARNING1) $(WARNING2) -export-dynamic $(LIBMYSQL) L_FLAGS = -lz -lm -lpthread -lcrypt $(LIBMYSQL) OBJ_DIR = Obj/ SRC_DIR = Source/ MUD_EXE = project MUD_DIR = TestP/ LOG_DIR = $(MUD_DIR)Files/Logs/ ECHOCMD = echo -e L_GREEN = \e[1;32m L_WHITE = \e[1;37m L_BLUE = \e[1;34m L_RED = \e[1;31m L_NRM = \e[0;00m DATE = `date +%d-%m-%Y` FILES = $(wildcard $(SRC_DIR)*.cpp) C_FILES = $(sort $(FILES)) O_FILES = $(patsubst $(SRC_DIR)%.cpp, $(OBJ_DIR)%.o, $(C_FILES)) all: @$(ECHOCMD) " Compiling $(L_RED)$(MUD_EXE)$(L_NRM)."; @$(MAKE) -s build build: $(O_FILES) @rm -f $(MUD_EXE) $(COMPILER) -o $(MUD_EXE) $(L_FLAGS) $(O_FILES) @echo " Finished Compiling $(MUD_EXE)."; @chmod g+w $(MUD_EXE) @chmod a+x $(MUD_EXE) @chmod g+w $(O_FILES) $(OBJ_DIR)%.o: $(SRC_DIR)%.cpp @echo " Compiling $@"; $(COMPILER) -c $(C_FLAGS) $< -o $@ .cpp.o: $(COMPILER) -c $(C_FLAGS) $< clean: @echo " Complete compile on $(MUD_EXE)."; @rm -f $(OBJ_DIR)*.o $(MUD_EXE) @$(MAKE) -s build I like the functionality of the Makefile, instead of spitting out all the arguments etc, it just spits out the "Compiling [Filename]" etc. If I add -c to the L_FLAGS then it compiles (I think) but instead spits out stuff like: g++: Obj/Database.o: linker input file unused because linking not done After a full day of trying and research on google, I'm no closer to solving my problem, so I come to you guys to see if you can explain to me why all this is happening and if possible, steps to solve.

  • Optimize included files and uses in Delphi

    - by Roland Bengtsson
    I try to increase performance of Delphi 2007 and Codeinsight. In the application there are 483 files added in the DPR file. I don't know if it is imagination but I feel that I got better performance from Codeinsight by simply readd all files in the DPR. I also think (correct me if I'm wrong) that all files that are included in a uses section also should be included in the DPR file for best performance. My question is, does it exists a tool that scan the whole project and give a list what files are missing in the DPR file and what files can be removed? Would also be nice to have a list of uses that can be removed in the PAS files. Regards

  • Converting Multiple files to zip and saving them in ownCloud

    - by user1055380
    I wanted to convert an array with some css, js and html files into a zip file and save them in ownCloud (it has it's own framework but it's knowledge is not required.) What I am saving is an infinite loop of zip files, as in, a zip inside a zip so I can't even check that the code is working correctly or not. Please help. Here is the link to the code. <?php /* creates a compressed zip file */ $filename = $_GET["filename"]; function create_zip($files = array(),$destination = '',$overwrite = false) { //if the zip file already exists and overwrite is false, return false if(file_exists($destination) && !$overwrite) { return false; } //vars $valid_files = array(); //if files were passed in... if(is_array($files)) { //cycle through each file foreach($files as $file => $local) { //make sure the file exists if(file_exists($file)) { $valid_files[$file] = $local; } } } //if we have good files... if(count($valid_files)) { //create the archive $zip = new ZipArchive(); if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) { return false; } //add the files foreach($valid_files as $file => $local) { $zip->addFile($file, $local); } //debug //echo 'The zip archive contains ',$zip->numFiles,' files with a status of ',$zip->status; //close the zip -- done! $zip->close(); //check to make sure the file exists return file_exists($destination); } else { return false; } } $files_to_zip = array( 'apps/impressionist/css/mappingstyle.css' => '/css/mappingstyle.css', 'apps/impressionist/css/style.css' => '/css/style.css', 'apps/impressionist/js/jquery.js' => '/scripts/jquery.js', 'apps/impressionist/js/impress.js' => '/scripts/impress.js', realpath('apps/impressionist/output/'.$filename.'.html') => $filename.'.html' ); //if true, good; if false, zip creation failed $result = create_zip($files_to_zip, $filename.'.zip'); $save_file = OC_App::getStorage('impressionist'); $save_file ->file_put_contents($filename.'.zip',$files_to_zip); ?>

  • PHP FTP Upload thousands of files

    - by user275074
    Hi, I've written a small FTP class which I used to move files from a local server to a remote server. It does this by checking an array of local files with an array of files on the remote server. If the file exists on the remote server, it won't bother uploading it. The script works fine for small amounts of files, but I've noticed that the local server can have as many as 3000+ image files to transfer, this seems to cause the script to flop and only transfer a 100 or so. How can I modify the script to handle potentially thousands of image transfer files?

  • Nginx: Disallow index.html in URL

    - by Martin Vilcans
    We're generating a site consisting of only static files (using Assemble). Having the .html extension on URLs looks so nineties, so we generate every static HTML file in its own directory and call it index.html. For example, the url http://www.example.com/foo/bar/ is in the file /var/www/foo/bar/index.html. This works well, but there is one small thing nagging me: Now there are two possible URLs to the same resource: http://www.example.com/foo/bar/ (slash URL) http://www.example.com/foo/bar/index.html (index.html URL) By accident someone may link to the index.html form of the URL, which is bad for SEO and looks ugly (remember the nineties?). Is it possible in Nginx to give a 404 error on the index.html URL, but serve the slash URL? I tried this: location ~ /index\.html$ { return 404; } But it seems that Nginx does some internal rewrite of the slash URL to the index.html URL, and then matches this location so we get a 404 even on the slash URL. Note that to catch mistakes, we want index.html URLs to be an error, not just redirect to the slash URL.

  • Program freezing when syncing a ldap database (100+ entries added)

    - by djerry
    Hey guys, I'm updating a ldap database. I need to add a list of users to the db. I've written a simple foreach loop. There are about 180 users i need to add, but at the 128th user, the program freezes. I know ldap is really used for querying (fast), and that adding and modifying entries will not go as smooth as a search query, but is it normal that the program freezes while doing this? I'll post some code just in case. public static void SyncLDAPWithMySql(Novell.Directory.Ldap.LdapConnection _conn) { List<User> users = GetUsers(); int iteller = 0; foreach (User user in users) { if (!UserAlreadyInLdap(user, _conn)) { TelUser teluser = new TelUser(); teluser.Telephone = user.E164; teluser.Uid = user.E164; teluser.Company = "/"; teluser.Dn = ""; teluser.Name = "/"; teluser.DisplayName = "/"; teluser.FirstName = "/"; TelephoneDA.InsertUser(_conn, teluser ); } Console.WriteLine(iteller + " : " + user.E164); iteller++; } } private static bool UserAlreadyInLdap(User user, Novell.Directory.Ldap.LdapConnection _conn) { List<TelUser> users = TelephoneDA.GetAllEntries(_conn); foreach (TelUser teluser in users) { if (teluser.Telephone.Equals(user.E164)) return true; } return false; } public static int InsertUser(LdapConnection conn, TelUser user) { int iResponse = IsTelNumberUnique(conn, user.Dn, user.Telephone); if (iResponse == 0) { LdapAttributeSet attrSet = MakeAttSet(user); string dnForPhonebook = configurationManager.AppSettings.Get("phonebookDn"); LdapEntry ent = new LdapEntry("uid=" + user.Uid + "," + dnforPhonebook, attrSet); try { conn.Add(ent); } catch (Exception ex) { Console.WriteLine(ex.Message); } } return iResponse; } Am i adding too many entries at a time??? Thanks in advance.

  • Python program to search for specific strings in hash values (coding help)

    - by Diego
    Trying to write a code that searches hash values for specific string's (input by user) and returns the hash if searchquery is present in that line. Doing this to kind of just learn python a bit more, but it could be a real world application used by an HR department to search a .csv resume database for specific words in each resume. I'd like this program to look through a .csv file that has three entries per line (id#;applicant name;resume text) I set it up so that it creates a hash, then created a string for the resume text hash entry, and am trying to use the .find() function to return the entire hash for each instance. What i'd like is if the word "gpa" is used as a search query and it is found in s['resumetext'] for three applicants(rows in .csv file), it prints the id, name, and resume for every row that has it.(All three applicants) As it is right now, my program prints the first row in the .csv file(print resume['id'], resume['name'], resume['resumetext']) no matter what the searchquery is, whether it's in the resumetext or not. lastly, are there better ways to doing this, by searching word documents, pdf's and .txt files in a folder for specific words using python (i've just started reading about the re module and am wondering if this may be the route, rather than putting everything in a .csv file.) def find_details(id2find): resumes_f=open("resume_data.csv") for each_line in resumes_f: s={} (s['id'], s['name'], s['resumetext']) = each_line.split(";") resumetext = str(s['resumetext']) if resumetext.find(id2find): return(s) else: print "No data matches your search query. Please try again" searchquery = raw_input("please enter your search term") resume = find_details(searchquery) if resume: print resume['id'], resume['name'], resume['resumetext']

  • Zabbix doesn't update value from file neither with log[] nor with vfs.file.regexp[] item

    - by tymik
    I am using Zabbix 2.2. I have a very specific environment, where I have to generate desired data to file via script, then upload that file to ftp from host and download it to Zabbix server from ftp. After file is downloaded, I check it with log[] and vfs.file.regexp[] items. I use these items as below: log[/path/to/file.txt,"C.*\s([0-9]+\.[0-9])$",Windows-1250,,"all",\1] vfs.file.regexp[/path/to/file.txt,"C.*\s([0-9]+\.[0-9])$",Windows-1250,,,\1] The line I am parsing looks like below: C: 8195Mb 5879Mb 2316Mb 28.2 The value I want to extract is 28.2 at the end of file. The problem I am currently trying to solve is that when I update the file (upload from host to ftp, then download from ftp to Zabbix server), the value does not update. I was trying only log[] at start, but I suspect, that log[] treat the file as real log file and doesn't check the same lines (althought, following the documentation, it should with "all" value), so I added vfs.file.regexp[] item too. The log[] has received a value in past, but it doesn't update. The vfs.file.regexp[] hasn't received any value so far. file.txt has got reuploaded and redownloaded several times and situation doesn't change. It seems that log[] reads only new lines in the file, it doesn't check lines already caught if there are any changes. The zabbix_agentd.log file doesn't report any problem with access to file, nor with regexp construction (it did report "unsupported" for log[] key, when I had something set up wrong). I use debug logging level for agent - I haven't found any interesting info about that problem. I have no idea what I might be doing wrong or what I do not know about how Zabbix is performing these checks. I see 2 solutions for that: adding more lines to the file instead of making new one or making new files and check them with logrt[], but those doesn't satisfy my desires. Any help is greatly appreciated. Of course I will provide additional information, if requested - for now I don't know what else might be useful.

  • On a Hudson master node, what are the .tmp files created in the workspace-files folder?

    - by Patrick Johnmeyer
    Question: In the path HUDSON_HOME/jobs/<jobname>/builds/<timestamp>/workspace-files, there are a series of .tmp files. What are these files, and what feature of Hudson do they support? Background Using Hudson version 1.341, we have a continuous build task that runs on a slave instance. After the build is otherwise complete, including archiving the artifacts, task scanner, etc., the job appears to hang for a long period of time. In monitoring the master node, I noted that many .tmp files were being created and modified under builds//workspace=files, and that some of them were very large. This appears to be causing the delay, as the job completed at the same time that files in this path stopped changing. Some key configuration points of the job: It is tied to a specific slave node It builds in a 'custom workspace' It triggers a downstream job that builds in the same custom workspace on the same slave node

  • Mathmatic errors in basic C++ program

    - by Heather
    I am working with a basic C++ program to determine the area and perimeter of a rectangle. My program works fine for whole numbers but falls apart when I use any number with a decimal. I get the impression that I am leaving something out, but since I'm a complete beginner, I have no idea what. Below is the source: #include <iostream> using namespace std; int main() { // Declared variables int length; // declares variable for length int width; // declares variable for width int area; // declares variable for area int perimeter; // declares variable for perimeter // Statements cout << "Enter the length and the width of the rectangle: "; // states what information to enter cin >> length >> width; // user input of length and width cout << endl; // closes the input area = length * width; // calculates area of rectangle perimeter = 2 * (length + width); //calculates perimeter of rectangle cout << "The area of the rectangle = " << area << " square units." <<endl; // displays the calculation of the area cout << "The perimeter of the rectangle = " << perimeter << " units." << endl; // displays the calculation of the perimeter system ("pause"); // REMOVE BEFORE RELEASE - testing purposes only return 0; }

  • How to determine on which file system a file was created in Java

    - by rafrafUk
    Hi Everyone! I get files in different formats coming from different systems that I need to import into our database. Part of the import process it to check the line length to make sure the format is correct. We seem to be having issues with files coming from UNIX systems where one character is added. I suspect this is due to the return carriage being encoded differently on UNIX and windows platform. Is there a way to detect on which file system a file was created, other than checking the last character on the line? Or maybe a way of reading the files as text and not binary which I suspect is the issue? Thanks Guys !

  • write a program that prompts the user to input five decimal numbers

    - by user312309
    This is the question. write a program that prompts the user to input five decimal numbers. the program should then add the five decimal numbers, convert the sum to the nearest integer,m and print the result. This is what I've gotten so far: // p111n9.cpp : Defines the entry point for the console application. // #include <iostream> using namespace std; double a, b , c , d , e, f; int main(int argc, char* argv[]) { cout << "enter 5 decimals: " << endl; cin >> a >> b >> c >> d >> e; f = a + b + c + d + e; return 0; } Now I just need to convert the sum(f) to the nearest integer, m and print the result. How do I do this?

  • Bash - replacing targeted files with a specific file, whitespace in directory names

    - by Dispelwolf
    I have a large directory tree of files, and am using the following script to list and replace a searched-for name with a specific file. Problem is, I don't know how to write the createList() for-loop correctly to account for whitespace in a directory name. If all directories don't have spaces, it works fine. The output is a list of files, and then a list of "cp" commands, but reports directories with spaces in them as individual dirs. aindex=1 files=( null ) [ $# -eq 0 ] && { echo "Usage: $0 filename" ; exit 500; } createList(){ f=$(find . -iname "search.file" -print) for i in $f do files[$aindex]=$(echo "${i}") aindex=$( expr $aindex + 1 ) done } writeList() { for (( i=1; i<$aindex; i++ )) do echo "#$i : ${files[$i]}" done for (( i=1; i<$aindex; i++ )) do echo "/usr/bin/cp /cygdrive/c/testscript/TheCorrectFile.file ${files[$filenumber]}" done } createList writeList

  • Xcode can't find imported header files

    I've used other IDE's in the past but am new to Xcode. I'm trying to bring in a bunch of C code from an open source project. I've imported them into a new Group and the .c files all show up under Implementation Files and the full list of files shows up in the Groups/Files group as well as my project directory in the finder. When I try to include or import one of these header files, code completion even works so I know Xcode is seeing them. But then when I go to build it says "no such file or directory". How can I get these files to import into my code?

  • directory monitoring

    - by foz1284
    Hi, What is the best way for me to check for new files added to a directory, I dont think the filesystemwatcher would be suitable as this is not an always on service but a method that runs when my program starts up. there are over 20,000 files in the folder structure I am monitoring, at present I am checking each file individually to see if the filepath is in my database table, however this is taking around ten minutes and I would like to speed it up is possible, I can store the date the folder was last checked - is it easy to get all files with createddate last checked date. anyone got any Ideas? Thanks Mark

  • Distribution of many small classes

    - by Moo-Juice
    Hi All, I have a base class called EventArgs. Derived from this are many, many specializations that represent event arguments for a particular kind of event. Consumers of these events may need some, many, or very few of these argument classes. My question is, would you provide a header file for each type (e.g, 50+ header files for the varying ones), would you try to group them in to families and have a 'common' header file for those, or would you throw caution to the window and throw them in to one easy-of-use header file that can just be included? Another approach might be to have 50 header files, and then I could introduce some "family" header files that included particular ones. Not sure about the naming conventions for these kinds of things so it is obvious what is where. I know there may not be a hard and fast rule, but wondering what other developers have done when they find themselves writing many little classes. Thanks in advance.

  • MySQL log files deletion

    - by aneez
    I have a master and slave database running on different nodes. The master DB is subjected to huge no. of inserts/updates. The master DB size is close to 6 GB, while the log files are now occupying a space of more than 120 GB. I am running out of disk space and need to get rid of the log files. Will deleting the log files in anyway affect the slave DB ? Presently, the slave is just a couple of seconds behind the master. Is there someplace where I can see what steps I need to follow to delete those files eg. 1)Shut down the slave 2)Shut down the master 3)Delete the log files 4)Start the Master 5)Start the Slave Do I need to inform the slave that the log files have been deleted ?? If yes, what is the way to do it ? Any help would be appreciated. Thanks

  • User Produtivity Kit - Powerful Packages (Part 1)

    - by [email protected]
    User Productivity Kit provides the ability to create a variety of content types including robust topics on system process and web pages with formatted text and graphics. There are times when you want to enhance content with media types not naively created by User Productivity Kit, media types such as video, custom animations, forms, and more. One method of doing this is to maintain these media files on a web server - separate from the User Productivity Kit player content and link to the files using absolute URLs such as http://myserver/overview.html. While this will get you going, you won't benefit from the content management capabilities of the UPK Developer. Features such as check-in / check-out, history, document properties, folder permissions and more are not available to this external content. Further, if you ever need to move that content to a server with a different name or domain, you'd need to update all your links. UPK version 3.1 introduced a new document type - the package. A package is a group of folders and files that you manage in the Developer library as a single document. These package documents work in the same manner as any other document in the library and you can use all of the collaborative content development features you see with other document types. Packages can be used for anything from single Word documents, PDF files, and graphics to more intricate sets of inter-related files commonly seen with HTML files and their graphics, style sheets, and JavaScript files. The structure of the files and folders within a package will always be preserved so this means that any relative links between files in the package will work. For example, an HTML file containing an image tag with a relative link to a graphic elsewhere in the same package will continue to function properly both when viewed in the Developer and when published to outputs such as the UPK Player. Once you start to use packages, you'll soon discover that there is a lot of existing content that can be re-purposed by placing it into UPK packages. Packages are easily created by selecting File...New...Package. Files can be added in a number of ways including the "Add Files" button, copy & paste from Windows Explorer, and drag & drop. To use one of the files in the package, just create a link to the file in the package you want to target. This is supported throughout the Developer in places such as section & topic concepts, frame links and hyperlinks in web pages. A little more challenging is determining how to structure packages in your library. As I mentioned earlier, a package can contain anything from a single file to dozens of files and folders. So what should you do? You could create a package for each file. You could create one package for all your files. But which one is right? Well, there's not a right and wrong answer to this question. There are advantages and disadvantages to each. The right decision will be influenced by the package files themselves, the structure of the content in the library, the size and working style of the development team, how content is shared between different outlines and more. The first consideration can be assessed the quickest. If the content to be placed in the package is composed of multiple files and those files reference each other, they should be in the same package. There are loads of examples of this type of content. HTML files with graphics and style sheets, HTML files with embedded Flash movies, and Word documents saved as HTML are all examples where the content is composed of multiple files and the files reference each other in some way. Content like this should always be placed in a singe package such that these relative links between the files are preserved and play properly in the UPK Player. In upcoming posts, I'll explain additional considerations.

  • Strange things appear on running the program

    - by FILIaS
    Hey! I'm fixing a program but I'm facing a problem and I cant really realize what's the wrong on the code. I would appreciate any help. I didnt post all the code...but i think with this part you can get an idea of it. With the following function enter() I wanna add user commands' datas to a list. eg. user give the command: "enter james bond 007 gun" 'james' is supposed to be the name, 'bond' the surname, 007 the amount and the rest is the description. I use strtok in order to 'cut' the command,then i put each name on a temp array. Then i call InsertSort in order to put the datas on a linked list but in alphabetical order depending on the surname that users give. I wanna keep the list on order and put each time the elements on the right position. /* struct for all the datas that user enters on file*/ typedef struct catalog { char short_name[50]; char surname[50]; signed int amount; char description[1000]; struct catalog *next; }catalog,*catalogPointer; catalogPointer current; catalogPointer head = NULL; void enter(void)//user command: enter <name> <surname> <amount> <description> { int n,j=2,k=0; char temp[1500]; char command[1500]; while (command[j]!=' ' && command[j]!='\0') { temp[k]=command[j]; j++; k++; } temp[k]='\0'; char *curToken = strtok(temp," "); printf("temp is:%s \n",temp); char short_name[50],surname[50],description[1000]; signed int amount; //short_name=(char *)malloc(sizeof (char *)); //surname=(char *)malloc(sizeof (char *)); //description=(char *)malloc(sizeof (char *)); //amount=(int *)malloc(sizeof (int *)); printf("\nWhat you entered for saving:\n"); for (n = 0; curToken !='\0'; ++n) { if (curToken) { strncpy(short_name, curToken, sizeof (char *)); / } printf("Short Name: %s \n",short_name); curToken = strtok(NULL," "); if (curToken) strncpy(surname, curToken, sizeof (char *)); / printf("SurName: %s \n",surname); curToken = strtok(NULL," "); if (curToken) { char *chk; amount = (int) strtol(curToken, &chk, 10); if (!isspace(*chk) && *chk != 0) fprintf(stderr,"Warning: expected integer value for amount, received %s instead\n",curToken); } printf("Amount: %d \n",amount); curToken = strtok(NULL,"\0"); if (curToken) { strncpy(description, curToken, sizeof (char *)); } printf("Description: %s \n",description); break; } if (findEntryExists(head, surname) != NULL) printf("\nAn entry for <%s %s> is already in the catalog!\nNew entry not entered.\n",short_name,surname); else { printf("\nTry to entry <%s %s %d %s> in the catalog list!\n",short_name,surname,amount,description); InsertSort(&head,short_name, surname, amount, description); printf("\n**Entry done!**\n"); } // Maintain the list in alphabetical order by surname. } /********Uses special case code for the head end********/ void SortedInsert(catalog** headRef, catalogPointer newNode,char short_name[],char surname[],signed int amount,char description[]) { strcpy(newNode->short_name, short_name); strcpy(newNode->surname, surname); newNode->amount=amount; strcpy(newNode->description, description); // Special case for the head end if (*headRef == NULL||(*headRef)->surname >= newNode->surname) { newNode->next = *headRef; *headRef = newNode; } else { // Locate the node before the point of insertion catalogPointer current = *headRef; catalogPointer temp=current->next; while ( temp!=NULL ) { if(strcmp(temp->surname,newNode->surname)<0 ) current = temp; } newNode->next = temp; temp = newNode; } } // Given a list, change it to be in sorted order (using SortedInsert()). void InsertSort(catalog** headRef,char short_name[],char surname[],signed int amount,char description[]) { catalogPointer result = NULL; // build the answer here catalogPointer current = *headRef; // iterate over the original list catalogPointer next; while (current!=NULL) { next = current->next; // tricky - note the next pointer before we change it SortedInsert(&result,current,short_name,surname,amount,description); current = next; } *headRef = result; } Running the program I get these strange things (garbage?)... Choose your selection: enter james bond 007 gun Your command is: enter james bond 007 gun temp is:james What you entered for saving: Short Name: james SurName: Amount: 0 Description: 0T?? Try to entry james 0 0T?? in the catalog list! Entry done! Also I'm facing a problem on how to use the 'malloc' on this program. Thanks in advance. . .

  • Elapsed time of running a C program

    - by yCalleecharan
    Hi, I would like to know what lines of C code to add to a program so that it tells me the total time that the program takes to run. I guess there should be counter initialization near the beginning of main and one after the main function ends. Is the right header clock.h? Thanks a lot... Update I have a Win Xp machine. Is it just adding clock() at the beginning and another clock() at the end of the program? Then I can estimate the time difference. Yes, you're right it's time.h. Here's my code: #include <stdio.h> #include <stdlib.h> #include <math.h> #include <share.h> #include <time.h> void f(long double fb[], long double fA, long double fB); int main() { clock_t start, end; start = clock(); const int ARRAY_SIZE = 11; long double* z = (long double*) malloc(sizeof (long double) * ARRAY_SIZE); int i; long double A, B; if (z == NULL) { printf("Out of memory\n"); exit(-1); } A = 0.5; B = 2; for (i = 0; i < ARRAY_SIZE; i++) { z[i] = 0; } z[1] = 5; f(z, A, B); for (i = 0; i < ARRAY_SIZE; i++) printf("z is %.16Le\n", z[i]); free(z); z = NULL; end = clock(); printf("Took %ld ticks\n", end-start); printf("Took %f seconds\n", (double)(end-start)/CLOCKS_PER_SEC); return 0; } void f(long double fb[], long double fA, long double fB) { fb[0] = fb[1]* fA; fb[1] = fb[1] - 1; return; } Some errors with MVS2008: testim.c(16) : error C2143: syntax error : missing ';' before 'const' testim.c(18) :error C2143: syntax error : missing ';' before 'type' testim.c(20) :error C2143: syntax error : missing ';' before 'type' testim.c(21) :error C2143: syntax error : missing ';' before 'type' testim.c(23) :error C2065: 'z' : undeclared identifier testim.c(23) :warning C4047: '==' : 'int' differs in levels of indirection from 'void *' testim.c(28) : error C2065: 'A' : undeclared identifier testim.c(28) : warning C4244: '=' : conversion from 'double' to 'int', possible loss of data and it goes to 28 errors. Note that I don't have any errors/warnings without your clock codes. LATEST NEWS: I unfortunately didn't get a good reply here. But after a search on Google, the code is working. Here it is: #include <stdio.h> #include <stdlib.h> #include <math.h> #include <share.h> #include <time.h> void f(long double fb[], long double fA, long double fB); int main() { clock_t start = clock(); const int ARRAY_SIZE = 11; long double* z = (long double*) malloc(sizeof (long double) * ARRAY_SIZE); int i; long double A, B; if (z == NULL) { printf("Out of memory\n"); exit(-1); } A = 0.5; B = 2; for (i = 0; i < ARRAY_SIZE; i++) { z[i] = 0; } z[1] = 5; f(z, A, B); for (i = 0; i < ARRAY_SIZE; i++) printf("z is %.16Le\n", z[i]); free(z); z = NULL; printf("Took %f seconds\n", ((double)clock()-start)/CLOCKS_PER_SEC); return 0; } void f(long double fb[], long double fA, long double fB) { fb[0] = fb[1]* fA; fb[1] = fb[1] - 1; return; } Cheers
