/*
Class -> It is a collection of data member and member Functions

Data Member -> Variables(Container to store values/data)
Ex - int a = 10;

Member Functions -> function(Group of code that perform specific task)

void add(int a,int b){
    cout<<a+b<<endl;
}


Object -> Real world Entity/ Copy of class

Encapsulation -> Class is an Example of encapsulation
