  • C String input confusion

    - by ahref
    C really isn't my strong point and after reading 3 chapters of a book on the subject and spending ages trying to get stuff working it just doesn't: #include <stdio.h> char *a,*b; int main( ) { char input[10]; fgets(input,sizeof input, stdin); a = input; fgets(input,sizeof input, stdin); b = input; printf("%s : %s",a,b); } I've isolated the problem from my main project. This code is meant to read in two strings and then print them however it seems to be setting a and b to point to input. Sample output from this code when A and B are entered is(don't worry about the \n's i can remove them): A B B : B How do i store the value of input in another variable eg. a or b so that in the above case A B A : B Is output? Thanks

  • I need to cut a portion of a string in linux

    - by Abeed Salam
    I have a file in a folder like this: installer-x86_64-XXX.XX-diagnostic.run The XXX.XX is a version number and I need the version number only. How to do it in linux? I have this code: #!/bin/bash current_ver=$(find /mnt/builds/current -name '*.run'|awk -F/ '{print $NF}') So this gives me just the name of the file correctly (minus the location, which I dont want). But how do I only get the XXX.XX version number into a variable such as $version

  • [python] parsing a string based on specified identifiers

    - by jml
    Let's say that I have the following text: in = "one aaa two bbbb three cccc" I would like to parse this into a group of variables that contain notworking = ["one", "two", "three"] v1,v2,v3 = in.split(notworking) I know that the example above won't work, but is there some utility in python that would allow me to use this sort of approach? I know what the identifiers will be in advance, so I would think that there has got to be a way to do this... Thanks for any help, jml

  • PHP split string into integer element and string

    - by David19801
    Hello, I have a string say: Order_num = "0982asdlkj" How can I split that into the 2 variables, with the number element and then another variable with the letter element in php? The number element can be any length from 1 to 4 say and the letter element fills the rest to make every order_num 10 characters long in total. I have found the php explode function...but don't know how to make it in my case because the number of numbers is between 1 and 4 and the letters are random after that, so no way to split at a particular letter. Please help as specifically as possible!

  • Calling a Function Based on a String Which Contains the Function Name

Im not a very big fan of using eval unless absolutely necessary.

  • Splitting string into array upon token

    - by Gnutt
    I'm writing a script to perform an offsite rsync backup, and whenever the rsyncline recieves some output it goes into a single variable. I then want to split that variable into an array upon the ^M token, so that I can send them to two different logger-sessions (so I get them on seperate lines in the log). My current line to perform the rsync result=rsync --del -az -e "ssh -i $cert" $source $destination 2>&1 Result in the log, when the server is unavailable ssh: connect to host offsite port 22: Connection timed out^M rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: unexplained error (code 255) at io.c(601) [sender=3.0.7]

  • String loops in Python

    - by Steve Hunter
    I have two pools of strings and I would like to do a loop over both. For example, if I want to put two labeled apples in one plate I'll write: basket1 = ['apple#1', 'apple#2', 'apple#3', 'apple#4'] for fruit1 in basket1: basket2 = ['apple#1', 'apple#2', 'apple#3', 'apple#4'] for fruit2 in basket2: if fruit1 == fruit2: print 'Oops!' else: print "New Plate = %s and %s" % (fruit1, fruit2) However, I don't want order to matter -- for example I am considering apple#1-apple#2 equivalent to apple#2-apple#1. What's the easiest way to code this? I'm thinking about making a counter in the second loop to track the second basket and not starting from the point-zero in the second loop every time.

  • Python: Removing particular character (u"\u2610") from string

    - by duhaime
    I have been wrestling with decoding and encoding in Python, and I can't quite figure out how to resolve my problem. I am looping over xml text files (sample) that are apparently coded in utf-8, using Beautiful Soup to parse each file, then looking to see if any sentence in the file contains one or more words from two different list of words. Because the xml files are from the eighteenth century, I need to retain the em dashes that are in the xml. The code below does this just fine, but it also retains a pesky box character that I wish to remove. I believe the box character is this character. (You can find an example of the character I wish to remove in line 3682 of the sample file above. On this webpage, the character looks like an 'or' pipe, but when I read the xml file in Komodo, it looks like a box. When I try to copy and paste the box into a search engine, it looks like an 'or' pipe. When I print to console, though, the character looks like an empty box.) To sum up, the code below runs without errors, but it prints the empty box character that I would like to remove. for work in glob.glob(pathtofiles): openfile = open(work) readfile = openfile.read() stringfile = str(readfile) decodefile = stringfile.decode('utf-8', 'strict') #is this the dodgy line? soup = BeautifulSoup(decodefile) textwithtags = soup.findAll('text') textwithtagsasstring = str(textwithtags) #this method strips everything between anglebrackets as it should textwithouttags = stripTags(textwithtagsasstring) #clean text nonewlines = textwithouttags.replace("\n", " ") noextrawhitespace = re.sub(' +',' ', nonewlines) print noextrawhitespace #the boxes appear I tried to remove the boxes by using noboxes = noextrawhitespace.replace(u"\u2610", "") But Python threw an error flag: UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 280: ordinal not in range(128) Does anyone know how I can remove the boxes from the xml files? I would be grateful for any help others can offer.

  • String update in SQL Server

    - by Thiyaneshwaran S
    Currently I have varchar field. The delimiter is "$P$P$". The delimiter will appear at least once and at most twice in the varchar data. Eg. Sample Heading$P$P$Sample description$P$P$Sample conclusion Sample Heading$P$P$Sample Description If the delimiter appears twice, I need to insert a text before the second occurance of the delimiter. Eg: Sample Heading$P$P$Sample DescriptionINSERT TEXT HERE$P$P$Sample Conclusion If the delimiter occurs only once, then I need to insert a text at the end of the field. Eg: Sample Heading$P$P$Sample DescriptionAPPEND TEXT HERE How this can be done in SQL query?

  • Issues with dynamically allocating a string array

    - by Jason Block
    Brand new to C. I am trying to dynamically allocate the array frags2 of size numberOfFrags and copy over the contents of the original array to it. I have tried numerous approaches and searching and do not understand what is going wrong here. Sizeof on the new array returns 0 instead of what I thought I malloc'd. Any help would be much appreciated! int main(int argc, const char* argv[]) { char* frags[MAX_FRAG_COUNT]; FILE* fp = fopen(argv[1], "r"); int numberOfFrags = ReadAllFragments(fp, frags, MAX_FRAG_COUNT); fclose(fp); char** frags2 = (char**)malloc(numberOfFrags * sizeof(char*)); for (int i = 0; i < numberOfFrags; i++) { frags2[i] = frags[i]; } qsort(frags2, sizeof(frags2) / sizeof(char *), sizeof(char*), cstring_cmp);

  • Removing the last character of a string IF it is $variable

    - by KeenLearner
    Hi there, I've made a little script to convert titles into url friendly things. ie: 'I am a title' becomes 'I_am_a_title' My script basically goes through and turns spaces, apostrophes, commas etc etc into an underscore. The problem is, sometimes my url's end up like this: 'i_am_a_title_' with a trailing underscore... So i figure, add a little bit to go through and search to see if the last character is an underscore on the final result, and if it is, then swap it. I looked into the strrchr() function but I seem to be hitting a wall of my own understanding. How is this sort of thing accomplished?

  • .Net SQL Server Connection String - hide password from other developers

    - by Chris Klepeis
    We're migrating one of our sites to ASP.Net. We do not want to use integrated security, which uses the windows account to connect to sql server (not going to get into why, its just out of the question). We created a username and password to connect to SQL Server, and would like to use that username and password, however, we also do not want other developers to see this information (easily read from the web.config).... I know it can be encrypted, but it can just as easily be decrypted by the developers - plus encryption has a performance hit. Is there any solution to this problem?

  • Java: How to return single char after string

    - by newSpringer
    I have a file directory which could look like either C:\projects\lab3\test\test.java or C:\projects\assignment3\test\test.java But the "lab3" or "assignment3" can appear anywhere in the directory, it is not a set directory What i want is to check to see if the directory either contains "lab" or "assignment" and get the number that follows. In this case "3" This is what i have so far if(directory.toLowerCase().contains("lab")){ } else if (directory.toLowerCase().contains("assignment")){ } but i do not know how to check for the char straight after the word?

  • How to convert string to integer?

    - by user1260584
    So I'm having a hard time with my situation and need some advice. I'm trying to convert my two Strings that I have into integers, so that I can use them in math equations. Here is what I tried, however it brings me an error in the app. ' equals.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { // TODO Auto-generated method stub num1 = edit.getText().toString(); num2 = edit.getText().toString(); int first = Integer.parseInt(num1); int second = Integer.parseInt(num2); edit.setText(first + second); } }); Is there something that I am doing wrong? Thank you for any help. EDIT: Yes this is Java. num1 and num2 are strings that I have previously named. What do you mean by trim?

  • assigning a string to another string

    - by user1509676
    Why this code is not running? Why str1 is not assigned to str2 ?? I know i have an option of using strcpy but i wish to know the reason why this is not working?? #include<stdio.h> int main() { char str1[]="hello"; char str2[10]; str2=str1; printf("%s",str2); return 0; } Whereas if I use pointers than it works like here.. #include<stdio.h> int main() ( char *s="good morning"; char *q; q=s; while(*q!='\0') { printf("%c",*q); q++; } return 0; } This works. Now the string has been copied via pointers so why such difference??
