[CODE] void dfs(graph g) { printf("whats wrong with me\n"); for (int i = 0;i < g.number_vertices;i++) { g.vertices[i].color = WHITE; g.vertices[i].p = NIL; } time = 0; printf("in dfs\n"); for (int i = 0;i < g.number_vertices;i++) { if (g.vertices[i].color == WHITE) { // dfs_visit(g, i); printf("i: %d\n",i); } } } …

I modified your code somewhat to display the intial/final values of c1/c2....What do you notice? [CODE] #include <stdio.h> int main() { char c1 = 0, c2 = 0; fprintf(stdout, "our initial values c1->%d, c2->%d\n", c1, c2); printf("Enter a character: "); scanf("%c", &c1); printf("Enter another character: "); scanf("%c", &c2); fprintf(stdout, "\nour …

Here's some code to demonstrate what happens when you cast an unsigned long to unsigned char... [CODE] #include <stdio.h> #include <stdlib.h> unsigned long myint = 1234567890; int main(int argc, char**argv) { int i = 0; unsigned char *cptr = (unsigned char*)&myint;/*cast myint to unsigned char*/ for (i = 0; i …

I'm pretty sure you don't have a memory leak...an array out of bounds yes but memory leak no...

Because the compiler padded the structure elements up to whole bytes. one byte for signed int a:3; two bytes for unsigned int b:13; and on byte for unsigned int c:1; Try using the attribute packed like below and you'll get three bytes because again the compiler will pad the end …

Yup...have some suggestions... 1. use read and write instead of fread and fwrite

When you want to left or right shift some bits...or splice some addresses together like below..So when would you need this skill? Hardware programming comes to mind..

You know it took Linus Torvalds years to make the very first 'very simple' Linux kernel. If your interested in this area ckeck out Minix.

You need to post 255 lines of code to ask a question about an array of structures?

You realy should google C functions and C control statements....You'll find the answers in these queries...

Shouldn't this end with a NULL execve(argv[0], argv, envp, NULL); Ooops my mistake.

You said you'd like to write a program - well what do you have so far.

Well if I had to do this, I would investigate binary trees or get the book "The C Programming Language" which has an example of this code...

You should get a table of ascii characters and look up the character equivalent for 10.

Try this: [CODE] int main(int argc, char* argv[]) { printf("%lf\n",(0.99F - 0.90F - 0.09F)); } [/CODE]

I know this is knit picking... [QUOTE] We all know that we can use the name of an array as the pointer to that array, [/QUOTE] The name of an array is a label which is a convenient human readable memory address. Its not a pointer...

Unless its a requirement I won't use fork in this situation...I would use threads..

Which operating system are we talking about here?

Volatile tells the compiler that a variable may be changed in ways not explicitly specified by the program - According to C: The complete Reference. This means the volatile variable may be changed by forces outside of the current process(usually the kernel, hardware or another process) so don't make any …
