Apart from what lh_mouse says about C++, in C if your function is declared to return an int and there is no return statement the returned value is undefined (not to be confused with undefined behavior, which only happens on this case if you *use* the value returned by that function.) So you can omit the return at the end of `main' on your toy C program unless you plan to use the process' exit value. ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
