  • Direct invocation vs indirect invocation in C

    - by Mohit Deshpande
    I am new to C and I was reading about how pointers "point" to the address of another variable. So I have tried indirect invocation and direct invocation and received the same results (as any C/C++ developer could have predicted). This is what I did: int cost; int *cost_ptr; int main() { cost_ptr = &cost; //assign pointer to cost cost = 100; //intialize cost with a value printf("\nDirect Access: %d", cost); cost = 0; //reset the value *cost_ptr = 100; printf("\nIndirect Access: %d", *cost_ptr); //some code here return 0; //1 } So I am wondering if indirect invocation with pointers has any advantages over direct invocation or vice-versa. Some advantages/disadvantages could include speed, amount of memory consumed performing the operation (most likely the same but I just wanted to put that out there), safeness (like dangling pointers) , good programming practice, etc. 1Funny thing, I am using the GNU C Compiler (gcc) and it still compiles without the return statement and everything is as expected. Maybe because the C++ compiler will automatically insert the return statement if you forget.

  • Fixed footer not displaying the bottom-most list item

    - by Mohit Deshpande
    Here is my XML layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ListView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/list" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content"> </ListView> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentBottom="true"> <EditText xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="1" /> <Button xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="2" /> </LinearLayout> </RelativeLayout> Which causes this problem: The listview item (outlined in red) is behind the fixed footer and cannot be used. Any solutions?

  • Create Silverlight application in Blend then migrate to Visual Studio

    - by Mohit Deshpande
    I want to make a Silverlight application in Expression Blend because of the rich UI and navigation of Blend. But I want to store the Silverlight application in an ASP.NET MVC web project. When I try to make a new Silverlight application, the default web application is an ASP.NET Web application (or web site, if I'm wrong). Can I make a single Silverlight application (no web project) then import in an ASP.NET MVC application? How can I do this?

  • What is a good project structure in C

    - by mohit
    Hi, I have been working in Java/J2ee projects, in which I follow the Maven structure. I want to develop [say a command line interpreter in linux {ubuntu}] in C. I never develop projects in C. I want to know what project structure I should follow.

  • Persist changes in C

    - by Mohit Deshpande
    I am developing a database-like application that stores a a structure containing: struct Dictionary { char *key; char *value; struct Dictionary *next; }; As you can see, I am using a linked list to store information. But the problem begins when the user exits out of the program. I want the information to be stored somewhere. So I was thinking of storing the linked list in a permanent or temporary file using fopen, then, when the user starts the program, retrieve the linked list. Here is the method that prints the linked list to the console: void PrintList() { int count = 0; struct Dictionary *current; current = head; if (current == NULL) { printf("\nThe list is empty!"); return; } printf(" Key \t Value\n"); printf(" ======== \t ========\n"); while (current != NULL) { count++; printf("%d. %s \t %s\n", count, current->key, current->value); current = current->next; } } So I am thinking of modifying this method to print the information through fprintf instead of printf and then the program would just get the infomation from the file. Could someone help me on how I can read and write to this file? What kind of file should it be, temporary or regular? How should I format the file (like I was thinking of just having the key first, then the value, then a newline character)?

  • Enter Password in C

    - by Mohit Deshpande
    I am aware that it is not possible to echo the * while you type in standard ANSI C. But is there a way to display nothing while someone is typing their password in the console. What I mean is like the sudo prompts in a Unix/Linux terminal. Like if you type in the command: sudo cp /etc/somefile ~/somedir. You are usually prompted for the root password. And while you type it in, the terminal displays nothing. Is this effect possible in C? If it is, how?

  • Program execution stop at scanf???

    - by Mohit Deshpande
    main.c (with all the headers like stdio, stdlib, etc): int main() { int input; while(1) { printf("\n"); printf("\n1. Add new node"); printf("\n2. Delete existing node"); printf("\n3. Print all data"); printf("\n4. Exit"); printf("Enter your option -> "); scanf("%d", &input); string key = ""; string tempKey = ""; string tempValue = ""; Node newNode; Node temp; switch (input) { case 1: printf("\nEnter a key: "); scanf("%s", tempKey); printf("\nEnter a value: "); scanf("%s", tempValue); //execution ternimates here newNode.key = tempKey; newNode.value = tempValue; AddNode(newNode); break; case 2: printf("\nEnter the key of the node: "); scanf("%s", key); temp = GetNode(key); DeleteNode(temp); break; case 3: printf("\n"); PrintAllNodes(); break; case 4: exit(0); break; default: printf("\nWrong option chosen!\n"); break; } } return 0; } storage.h: #ifndef DATABASEIO_H_ #define DATABASEIO_H_ //typedefs typedef char *string; /* * main struct with key, value, * and pointer to next struct * Also typedefs Node and NodePtr */ typedef struct Node { string key; string value; struct Node *next; } Node, *NodePtr; //Function Prototypes void AddNode(Node node); void DeleteNode(Node node); Node GetNode(string key); void PrintAllNodes(); #endif /* DATABASEIO_H_ */ I am using Eclipse CDT, and when I enter 1, then I enter a key. Then the console says . I used gdb and got this error: Program received signal SIGSEGV, Segmentation fault. 0x00177024 in _IO_vfscanf () from /lib/tls/i686/cmov/libc.so.6 Any ideas why?

  • Iterate through main function in C?

    - by Mohit Deshpande
    Here is my main function: int main(int argc, char **argv) { LoadFile(); Node *temp; char *key; switch (GetUserInput()) { case 1: temp = malloc(sizeof(Node)); printf("\nEnter the key of the new node: "); scanf("%s", temp->key); printf("\nEnter the value of the new node: "); scanf("%s", temp->value); AddNode(temp); free(temp); break; case 2: key = malloc(sizeof(char *)); printf("Enter the key of the node you want to delete: "); scanf("%s", key); DeleteNode(key); free(key); break; case 3: PrintAll(); break; case 4: SaveFile(); break; case 5: return 0; break; default: printf("\nWrong choice!\n"); break; } return 0; } The only problem with it is that after any case statement breaks, the program just exits out. I understand why, but I don't know how to fix it. I want the program to repeat itself each time even after the case statements. Would I just say: main(argc, argv); before every break statement?

  • Flex ItemRenderer/Editor ComboBox Issue...Puhleezz Help

    - by Mohit
    Hi EveryOne Beginner in Flex ...Even worse with item renderers... Have managed to add a Combobox to a datagrid using a itemEditor... I want to change the options in a combo box depending on the value selected by the user on a previous combo.. In the combo box i want to display a certain value (Model Name ) but for quering a table i'll pass the corresponding code of the model :(... sounds simple enough ..unfortunately not able to implement it I have found this problem on this site but the solution seems an overkill for my "small" problem..was hoping if anyone could guide me towards a more simpler solution... My xml comes as <item><mstValue>CH1</mstValue><mstRemarks>CARRIER</mstRemarks></item> <item><mstValue>CH2</mstValue><mstRemarks>TRANS</mstRemarks></item> <item><mstValue>CH3</mstValue><mstRemarks>YORK</mstRemarks></item> Now i have been able to show the values in a combo .if user selects CARRIER i want to pass CH1(dont know how to do it with itemeditors)...and then fetch values corresponding to CH1 from a table (second part of the problem)...in the sample below i used this.parentDocument.modelComboChanged(this.selectedItem) to pass the selected value ...instedd i need to pass the code for it which comes from the xml...Pls help this making me go crazy.... <mx:DataGrid id="chillerGrid" dataProvider="{chillerGridDp}" editable="true" itemRollOver="{ComponentUtil.setTooltip(event,this)}" itemRollOut="ComponentUtil.resetTooltip(event)" width="70%" height="160"> <mx:columns> <mx:DataGridColumn id="test" headerText="Model" dataField="model" editorDataField="value" editable="true" backgroundColor="#f4f2bd" width="100" > <mx:itemEditor> <mx:Component> <mx:ComboBox creationComplete="{if(text=='')selectedIndex=0;if(data &amp;&amp; data.contactType!=undefined)text=data.contactType.text();}" change="{if(text == ''){selectedIndex=0;if(data &amp;&amp; data.contactType!=undefined)text=data.contactType.text();};this.parentDocument.modelComboChanged(this.selectedItem)}" dataProvider="{this.parentDocument.arrColl1}" text="mstRemarks" labelField="mstRemarks" editable = "false" > <!--<mx:dataProvider > <mx:String></mx:String> <mx:String>Model1</mx:String> <mx:String>Model2</mx:String> <mx:String>Model3</mx:String> <mx:String>Model4</mx:String> <mx:String>Model5</mx:String> </mx:dataProvider>--> </mx:ComboBox> <!--<components:ComboBoxIn dataProvider="{this.parentDocument.arrColl1}" labelField="mstRemarks" /> --> </mx:Component> </mx:itemEditor> </mx:DataGridColumn> <mx:DataGridColumn headerText="Make" dataField="make" editorDataField="value" editable="true" backgroundColor="#f4f2bd" width="100" > <mx:itemEditor> <mx:Component> <mx:ComboBox creationComplete="{if(text=='')selectedIndex=0;if(data &amp;&amp; data.contactType!=undefined)text=data.contactType.text();}" change="{if(text == ''){selectedIndex=0;if(data &amp;&amp; data.contactType!=undefined)text=data.contactType.text();} }" labelField="@label" editable = "false" > <mx:dataProvider> <mx:String></mx:String> <mx:String>Carrier</mx:String> <mx:String>York</mx:String> <mx:String>Trane</mx:String> </mx:dataProvider> </mx:ComboBox> </mx:Component> </mx:itemEditor> </mx:DataGridColumn> <mx:DataGridColumn headerText="Chillers" dataField="chillers" width="200" editable="true"> <mx:itemEditor> <mx:Component> <mx:TextInput maxChars="49" /> </mx:Component> </mx:itemEditor> </mx:DataGridColumn> </mx:columns> </mx:DataGrid>

  • Imitate database in C

    - by Mohit Deshpande
    I am fairly new to C. (I have good knowledge of C# [Visual Studio] and Java [Eclipse]) I want to make a program that stores information. My first instinct was to use a database like SQL Server. But I don't think that it is compatible with C. So now I have two options: Create a struct (also typedef) containing the data types. Find a way to integrate SQLite through a C header file Which option do you think is best? Or do you have another option? I am kind of leaning toward making a struct with a typedef, but could be pursuaded to change my mind.

  • Arrow operator (->) usage in C

    - by Mohit Deshpande
    I am currently learning C by reading a good beginner's book called "Teach Yourself C in 21 Days" (I have already learned Java and C# so I am moving at a much faster pace). I was reading the chapter on pointers and the - (arrow) operator came up without explanation. I think that it is used to call members and functions (like the equivalent of the . (dot) operator, but for pointers instead of members). But I am not entirely sure. Could I please get an explanation and a code sample?

  • The concept of an Intent in Android?

    - by Mohit Deshpande
    I don't really understand the use and concept of an Intent. I DO understand that an activity are one visual interface and one endeavour that the user can partake in. I THINK an intent is used to launch and communicate between different activities. If so, then how would you accomplish that? A code sample would be helpful.
