In C++ programming language

Create the header file Shape.h.

In the header file define the interface Shape that has A double constant method named Perimeter() that takes no parameters.

A double constant method named Area() that takes no parameters.

And the class Square that publicly inherits Shape and has components Private double field named side.

Public overloaded constructor that takes one double parameter. It assigns the parameter to side if the parameter is positive; otherwise, it assigns 1 to side.

Public copy constructor.

Public assignment operator.

Public empty destructor.

Public set method for side. It assigns the parameter to side only if the parameter is positive; otherwise, it does nothing.

Public overridden Perimeter() method. It returns the perimeter of the square.

Public overridden Area() method. It returns the area of the square.

Public string constant method named ToString() that takes no parameters. It returns a string of side enclosed in parentheses.
