DO NOT use ideone for unix specific system calls. Granted that it is an
online compiler but it is best to test unix specific system calls on unix
itself..
Ok, so here goes.
A few basics that need to be told before hand..
*fork() system call creates a child process, and returns its process id to
the parent.
The child process is an exact replica of the parent process.
*
So, for example in this snippet of code,
int color = fork ();
color will have the child process' PID in the parent and 0 in the child.
so here is a line by line analysis of what happens
