As per the question integer class has only one member function input..but u have used one more member function in public section..instead of using one more function in public block..why cant we make code the fn input() as...int input()
{ cout<<"enter integer"; cin>>inte;return inte}..and use this func in division as u used the output fn..we dont have condition that the protected memebr doesnt return int.do we?

You *can*, but that doesn't mean you *should*. That's some seriously illegal hackery. It happens to work with usual C compilers but there's nothing that keeps the compiler from breaking it at any time, like by plugging in a garbage collecting allocator that makes the first field of any object an internal-use link item.
As it is not mentioned how many parameter I can take in function calc of class Character, I have used it to take two parameters.
