It is mostly environment dependant. If you will do the same program on TC(Turbo C) it will give you the answer as:
/*
5
5
7
9 - 8 - 8

In C programming your variable declaration should be exactly after at starting of your block(i.e after {(opening curly brace)). just alter the sequence :- put clrscr() after variable declaration.. It will run perfectly....Leave a comment:

When return 0 will be encountered function returns to O.S. with value as 0. So the exit(10) will never be executed.Leave a comment:

Why to use return type for string function as char*?
If we are using strcpy() for copying the string. As we are passing pointers to it It will copy the string & no need to return the string .This function will finely work with return type as void then why Ritchie has used it as char* strcpy()?
