C++ program to demonstrate Constructor Overloading

//class Shape with dim1 and dim2 as private members
//create two constructors of the class
//one with one argument and the other with two arguments
//object rectangle with two dimensions
//object square with only one dimension
//calculate their area

#include <iostream>
using namespace std;
