I am reaing from a file, and when i read, it takes it line by line, and prints it what i want exactly is i want an array of char holding all the chars in the file and print it once, this is the code i have if(strcmp(str[0],"@")==0) { FILE *filecomand; //char fname[40]; char line[100]; ...
how do you divide two integers and get a decimal answer? in xcode.. the only thing i could was find http://www.gnu.org/s/libc/manual/html_node/Integer-Division.html this method will not allow me to have a decimal answer... ...
Hello folks, This one is probably very simple, but I can't seem to get it working. I have this very simple snippet of code: #include <stdio.h> #include <string.h> int main(void) { char buf[100]; char *p = buf; strcpy(p, "Test string"); printf("%s\n", *p); } Which causes a segmentation fault when I run it. GDB outputs: ...

From man gets: Never use gets(). Because it is impossible to tell without knowing the data in advance how many characters gets() will read, and because gets() will continue to store characters past the end of the buffer, it is extremely dangerous to use. It has been used to break computer security. Use fg...
So in my game I need to simulate the physics in a hardware independent manner. I'm going to use a fixed time-step simulation, but I need to be able to calculate how much time is passing between calls. I tried this and got nowhere: #include <time.h> double time_elapsed; clock_t last_clocks = clock(); while (true) { time_elapsed = ( (...
Hi! I want the following code to print 11, but prints 12, except in the last case, where it prints 10. x=5; x1=x+(x=6); printf("%d\n",x1); x=5; x1=(x=x)+(x=6); printf("%d\n",x1); x=5; x1=(x+0)+(x=6); printf("%d\n",x1); x=5; x1=(x=5)+(x=6); printf("%d\n",x1); x=5; x1=(x=6)+x; printf("%d\n",x1); x=5; x1=(x=6)+(x=x); printf("%d...
i have an array of type char char *arg[100] this array its reading the data from somewhere, when that when i print arg[0], it prints the value "help", and when i print the arg[1], it prints the value "exit".. as an example what i want exactly is to change the arg[0] from "help" to anything else, like "man" how i can do that??? than...

I'm trying to write depth first search in C. In the search instead of maintaing a set of all the reachable nodes I instead have to mark the isVisited field in Vertex as a 1 for visited. Here's my data structs and my algo attempt. struct Vertex { char label; int isVisited; int numNeighbors; struct Vertex** neighbors; }; ...
I have a C# prototype that is heavily data parallel, and I've had extremely successful order of magnitude speed ups using the Parallel.For construct in .NETv4. Now I need to write the program in native code, and I'm wondering what my options are. I would prefer something somewhat portable across various operating systems and compilers, b...

Hi folks, I am experimenting with variable argument lists and seeing some strange results...

I'm in the middle of porting David Blei's original C implementation of Latent Dirichlet Allocation to Haskell, and I'm trying to decide whether to leave some of the low-level stuff in C.

Hello, gcc 4.4.4 c89 I will be adding to this list. So I am looking to NULL terminate it.

I was thinking in this case arrays and pointers where the same? struct company_p...
