Void functions can't return values.

You can, however, write return statements in them at the end to enhance user readability.

@joshi_nitish @Bikram 

even if u want to write a return statemnt for a void function(which is incorrect but lets suppose it compiles successfully ) then also return should be written like return; and not return(m+2);is it valid

---

    z=f(&i);

Is this correct? What does it mean?
