When you create a contact group, you are not creating subfolders for contacts, but rather another way to reference ____________________ at one time.

When you have multiple functions with the same name this is called ____________?

What will be an ideal response?

Consider the class definition:

``` class IntPair{ int first; int second;public: IntPair(int firstValue, int secondValue);// prefix operator++ here // postfix operator ++ here int getFirst( ) const; int getSecond( ) const; ``` a) Give declarations for prefix and postfix versions of operator++ b) Give definitions for prefix and postfix versions of operator++
