Computing Total Area of Multiple Shapes Using Polymorphism in C++
Define an abstract base class Shape and five derived classes: Circle, Square, Rectangle, Trapezoid, and Triangle. Use a virtual function to compute the area of each shape, then calculate their total sum. The program must use a base class pointer array, where each element points to an object of a derived class. Use PI = 3.1415926.
Input Format:
...

Understanding Static Types, Dynamic Types, and Polymorphism in C++
Static Type vs Dynamic Type
A static type is the type declared for an object at compile time. Once the compiler processes the declaration, the static type is fixed and never changes.
A dynamic type refers to the actual type of the object that a pointer or reference points to. Since the compiler cannot know the actual runtime type, the dynamic t ...
