Inheritance is a major contributing topic in C++ OOPS .

Answer 1

that is you can add more sub classes... You can now add yourself as a class easily)

Where do we use this

Consider your family. You need create a class for your dad, mom, brother. Eat(), work(), sleep() are the functions which will be same for all of the three classes. 

Without inheritance.
If we create these classes avoiding inheritance then we have to write all of these functions in each of three classes.
1.Here in your code there is duplication of three functions.
2.Chances of errors are more. Imagine you forgot an 'e' for brother. 😂

To avoid these we use INHERITANCE
NOW....

Create a super class family and write these three functions in it and inherit the rest of the classes from the family class, then we can simply avoid the duplication of data and increase re-usability(that is you can add more Subcl
