215: Create a C++ program that uses single inheritance to model a simple shape hierarchy. Implement a base class "Shape" with a virtual function "printArea." Derive classes "Rectangle" and "Triangle" from "Shape" and override the "printArea" function to calculate and display their respective areas.
