Object Oriented Programming OOP

Necessity is the mother of need .These little words lead to invent the programming methodology which is called OOP .The programmers found that to make large programs ,It is very hard by using the old ways of programming
So ,As in our life , every one of us is an object ,which has its own characteristics "properties", and has its own functions and roles in life "methods", the OOP depends on this methodology
Every object has its own properties which describes itself , and also has its own methods which describes his way of working inside the whole program
