strchr

Question:
Where can I see the source code to the function strchr?

Answer:
If you purchase a compiler such as the professional edition of VC++, the source code for all run-time library functions is included.

However, this routine is rather trivial. You could implement it like this:

char *mystrchar(char *string, int c)
{
   char *p;

   for (p = string; *p != '\0'; p++) {
      if (*p == c)
         return p;
   }
   return NULL;  // Char not found
}
