C++ PROGRAM Create a class MyClass with an integer data member ‘secret’. Provide a constructor and display method in the class. Create another class, MyFriendClass and make it a friend of the class MyClass. Provide a function change() in the class MyFriendClass which accepts an object of class MyClass (by reference) and an integer. The change() function should assign the integer passed as an argument to the data member ‘secret’ of the object received as input.   Sample Run : MyClass m(2) ; MyFriendClass mf ; mf.change(m,10) ; m.display() ; //Should print 10

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.
