c++ use OOP techiques Implement a shape hierarchy by using inheritance aand poolymorphisim. You must have your super class shape and 2 subclasses two-dimensional shape and three-dimensional shape. Under twodimensional shape, you have other subclasses, circle, square, and triangle. Under the three-dimensional shape you have the sphere, cube, and tetrahedron. Each twoEmployee name taxRate getName calcSalary String pStr String operator = operator << SalariedEm salary calcSalary HourlyEmp hours hourlyRate calcSalary CommEmp sales commRate calcSalary dimensional shape should contain a method getArea to calculate the area of the twodimensional shape. Each three-dimensional shape should have a method getArea and getVolume to calculate the surface area and volume, respectively, of the three-dimensional shape. Create a program that uses an array of shape references to objects of each concrete class in the hierarchy. The program should print a text description of the object to which each array element refers. Also, in the loop that processes all the shapes in the array, determine whether each shape is a two-dimensional shape or a threedimensional shape. If a shape is a two-dimensional shape, display it's area. If a shape is a three-dimensional shape, display its area and volume.
