Object Oriented Concepts
Class Basic unit of abstraction in C++ Extension of the concept of structures Provides a technique to bind data and functions together (Encapsulation) . . Data Members Variables declared inside the class Member Functions - Functions declared/defined inside the class Member Functions are also called as Methods .
Class - Implementation of Encapsulation (Access Specifiers) Public Members:- Accessed within and outside the class . . Protected Members:- Accessed within and only by derived classes Private Members:- Accessed only within the class .
Objects Instance of a class in memory Unique, identifiable, self - contained entity that contains . attributes and behaviours If class is viewed as a data type then object can be considered as a variable of class data type.
Constructors . Used for automatic initialization of instance variables during Object creation. Has the same name of the class and do not have return types (not even void) Invoked automatically when an object of its associated class is created
Constructors - Types . Default Constructor Takes no parameters and no return value (NOT even void) Automatically written by C++ if no user-defined constructor is present The programmer can redefine the default constructor.
Copy Constructor Takes only one argument which is of same class type Generally used to copy some selective data members of one object to another Automatically written by the compiler if no user defined copy constructor is present. default copy constructor takes exact copy of one object to another
