4. Simple Inheritance

Your task is to define two classes:

• Base class: Device
  • A method void printType() that prints:
     

Generic Device

• Derived class: Sensor (inherits publicly from Device)
  • A method void printSensor() that prints:
    Sensor Device

The program will:

1. Create a Sensor object.
2. Call printType() (inherited from base).
3. Call printSensor() (defined in derived).
   
    

Example

Output:

Generic Device
Sensor Device

Why this output?

• The base class method printType() is accessible because of public inheritance.
• The derived class method printSensor() prints its own message.
   

Question Significance

This problem demonstrates how a derived class can reuse base class functionality while adding its own behavior.
