Objects how do they help to solve problems?

Question

How can one understand objects better

Answer 1

Assume you are developing an application about student. In your program you should use many vars to store many necessary information about students , scores , courses and others. They are absolutely independent and you should control them yourself. In oop paradigm you store all of one student's data in it's object and you use that object to retrieve all of necessary information about that student without a lot of vars
