Polymorphism comes from the Greek for many shapes. So far, you have a basic form of polymorphism. If you use a base class pointer to an object, then you can access the base class behavior, and if you have a derived class pointer, you get the derived class behavior. This is not as trivial as it appears because the derived class can implement its own version of the base class methods, so you can have a different implementation of that behavior.
You can have more than one class derived from a base class:
class base { /*members*/ };
class derived1 : public base { /*members*/ };
class derived2 : public base { /*members*/ };
class derived3 : public base { /*members*/ };
Since C++ is strongly typed, it means that a pointer to one derived class cannot be used to point to another derived class. So you cannot use a derived1* pointer to access an...
