Counting Objects With a Static Base Member

A static data member in a base class is shared across the whole hierarchy, so it can count every object created, including derived ones.

Create a base class Entity with a public static int count; that is incremented in the Entity constructor. Define the static member outside the class as int Entity::count = 0;.

Create a derived class Player (empty body) whose constructor automatically runs the base constructor and bumps the counter.

After the runner creates one Entity and two Players, it prints Entity::count (see Expected Output).

Do NOT write a main function.
