Hello Experts, I have to write a program in C which, given the name of a day, returns all of the dates in this month that the day will be on. For example, if the input is "Sunday" the output should be: 5,12,19,26 (which are the days Sunday will be on this month.) Does any one have any idea how to do this? I have tried a lot. Please he...
I am surprised why this works? short main [] ={}; This is the only content in the file. It compiles correctly on gcc. But when i run it prints segmentation fault. When i rename main, compiler gives errors. Can anyone explain me what is going on here. ...
I am considering using a FAT file system for an embedded data logging application. The logger will only create one file to which it continually appends 40 bytes of data every minute. After a couple years of use this would be over one million write cycles. MY QUESTION IS: Does a FAT system change the File Allocation Table every time a fil...
Hello I have a bizarre problem with sprintf. Here's my code: void draw_number(int number,int height,int xpos,int ypos){ char string_buffer[5]; //5000 is the maximum score, hence 4 characters plus null character equals 5 printf("Number - %i\n",number); sprintf(string_buffer,"%i",number); //Get string printf("String - %s\n...
I have a "pointer" which keeps incrementing and I need to return the "head" of the pointer finally. I am in a dilemma to use either "pointer[0]" or have another variable called "head" and initialize it and return at the end. The former I feel makes the code looks soiled and later costs little memory. Any clean suggestion? ...
Hello Expert, I am able to get the current date but the output is like 9/1/2010,but my requirement is to get the current day like"Wednesday" not in form of integer value like 1.

Im writing a project in Objective-C but I'm relying quite much on plain old C since there's OpenGL involved. I have a data blob that I read to memory from a file in the following way: NSString *path = [[NSBundle mainBundle] pathForResource:@"iPadTest" ofType:@""]; NSFileHandle *file = [NSFileHandle fileHandleForReadingAtPath:path]; dat...
Guys I'm a novice. I have learnt C and Assembly(IA32) on Linux and I will also be learning a few more languages this year. I want to make my fundamentals strong and for that I need some tips from you guys as in, where will I find programs for practice? so that I solve them and get more and more experience.

Source code for matrix multiplication using pointer, dynamic memory allocation and then store them(all the three Matrix) in a file. ...
I have a function which creates an array of pointers. The function which allocates the memory returns the new memory pointer through a parameter passed to the function. The simplest code which can reproduce the problem is as follows: void foo (void** new_mem, size_t bytes) { *new_mem = malloc(bytes); } int main (void) { int**...
Hi, I'm currently working on an FTP client written in C, and it's working pretty good. I was successful in writing a function that connects to an FTP server and logs in with a username or password, but I'm having a problem with returning errors. I have setup a struct FTPError {}; with 3 fields: int An error code int An FTP error domain...
I wrote a Python extension in C, and my python program uses that extension. In order for it to work, I would have to install the extension on the user's system before my program can run. Is there a way to bypass that installation step and somehow just have the extension in my python package? The only compiled part obviously is the extens...
This was a contest Q: There are N numbers a[0],a[1]..a[N - 1]. Initally all are 0. You have to perform two types of operations : Increase the numbers between indices A and B by 1. This is represented by the command "0 A B" Answer how many numbers between indices A and B are divisible by 3. This is represented by the command "1 A B"....

So in Open CV we have such easy way of getting to some camera device and its data: #include "cv.h" #include "highgui.h" #include <stdio.h> // A Simple Camera Capture Framework int main() { CvCapture* capture = cvCaptureFromCAM( CV_CAP_ANY ); if( !capture ) { fprintf( stderr, "ERROR: capture is NULL \n" ); getchar(); re...
This is not a homework, it's more of a challenge from our prof but I'll be tagging it as one nonetheless. The problem is to create a typing game that has 3 levels with matching difficulty, different time limits (in seconds) and scores. Now I don't have any problems with the program itself, what I'm having problem is implementing the tim...

Has anyone had any experience in teaching programming in C to undergraduate students, who can be presumed never to have seen an editor before in their lives? I might soon face that predicament, and was thinking of basing myself on the K&R "The C Programming Language" book. Has anyone had a similar experience? What are your ideas/recomme...
