The Pair class

The first step is to write a non-templated Pair class. The class must have the following methods:

• Pair(): a default constructor that does nothing.
• Pair(int first, int second): a two-argument constructor that creates a pair with the given values.
• first(): an accessor that returns the value of the first member of the pair.
• second(): an accessor that returns the value of the second member of the pair.
• operator==(): overload the equality operator to compare two pairs in a position-independent fashion (i.e., the first and second can match in any order).

It will also need private data members to hold the two values.

As a reminder, here is the syntax for declaring the overloaded "==" operator:

     bool operator== (const Pair& rhs) const;

and the syntax for the function definition:

     bool Pair::operator== (const Pair& rhs) const {
        /* Code here to see if first==first and second==second,
         * OR first==second and second==first
         */
     }

Once you have completed the non-templated version of the Pair class, compile it with lab11.cpp to test it:

      g++ -Wall -ansi lab11.cpp Pair.cpp -o lab11
