Question

What is the difference between polymorphism and inheritance though both are used for reusability of code?

Answer 1

Polymorphism:

• Reusability of code is implemented through functions (or) methods.
• Polymorphism is the ability of a function to respond differently to different message.
• Polymorphism is achieved through overloading. 

Inheritance:

• Reusability of code is implemented through classes. 
• Inheritance is the process of creating derived classes from the base class or classes.
• Inheritance is achieved by various types of inheritances namely single, multiple, multilevel, hybrid and hierarchical inheritances.
