CPP Program To Implement Inheritance |
|
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.

SAMPLE INPUT AND OUTPUT:
House has 5 bedrooms
School has 180 classrooms
It area is 25000
