Alogarithm steps:

Step 1: Create the base class building. It has the blue print structure of the buildings.

Step 2: Create the derived class house from building class. It extends the buildings properties and also it has its own properties.

Step 3: Create the derived class school from building. School as have its unique properties.

Step 4: Give the definition to base and derived class methods.

Step 5:  Create the object for the derived classes school and house .

Step 6: Call the member function through the objects. Now derived classes object can call the base class methods also.

Step 7: Compile and run.
