We are required to remember that once a class is declared, a class becomes a so we can use the class name as the type for the pointer

valid data type.

Explanation:

When we create a class it becomes a valid data type that we can use in our program.The class data type can be used as a pointer.One such example that we use most often is the Linked List Nodes.First we create a class name Node and then create a pointer of type Node which points top another Node.

There are other examples also such as:-

Binary tree Nodes,Binary search tree Nodes etc.
