Well i think this is related to stack and how the data is stored by the OS in stack.

The return value for that function would be undefined. It would vary with different combinations of operating systems and compilers. Yes, it's got to do with how the compiler would manage the stack and what policies it has for otherwise undefined behavior. I got 0 with gcc 3.2, sleep() or no sleep().

the return result was 0. Or if we give a specific return then that value appears in the printf.

Of course, it would.

A quick look for functions and return values through _The_C_Programming_Language_ 2/e by Kernighan and Ritchie should leave no scope for doubts.
