Answer 1

It's because of classes that you utilize all your features of an object oriented programing.
1.Encapsulation
2.Data Hiding
3.Polymorphism
4.Abstraction
5.Inheritance

All these features allow us to make an efficient, programmer friendly code that is easily readable and understandable. You need this when you're working with a company or making a project on real data and the code is to be applied for commercial purposes.
