Question

Assuming there is no error in main() complete the class Rectangle and its functions.

int main()

{

     Rectangle rect1(3.4, 5.68);

     Rectangle rect2(2.4, 4.68);

     if (rect1-- != ++rect2) //increment/decrement will add & subtract by 1 of each data members of class

           cout << ”\n Both are not of same size”;

     else

           cout << ”\n Both are of same size”;

     rect1.show(); \\will display values 2.4, 4.68      

     Rectangle rect3 = rect1 + rect2;

     rect3.show(); \\will display values 5.8, 10.36

     system(“pause”);

     return 0;

}
