Object Oriented Paradigm

Object Oriented Paradigm
Object Oriented Paradigm also called oop is a model for writing computer programs.

Features of OOP
  • Abstraction.
  • Encapsulation.
  • Polymorphism.
  • Inheritance.


Abstraction

Using the essential feature of a programming language  and hiding the complexity is known as abstraction.

Encapsulation
Wrapping of data members & the member function within the class is known as Encapsulation.
It is based on the concept of data hiding & data hiding says that we can't access the private element of class without the help of member function of that class.

Polymorphism
Ability to assume several forms is known as polymorphism and we can achieve polymorphism in C++ by 3 ways.
  1. By function Overloading.
  2. Operator Overloading.
  3. Virtual Function.

Inheritance
It is taken from the real world where the parent class is known as base class and the child class is known as derived class.
It says that child class can access all property of their parent class but parent class can't access the property of child class.

Types of Inheritance
  1. Single inheritance.
  2. Multiple inheritance.
  3. Hierarchical inheritance.
  4. Multi level inheritance.
  5. Hybrid inheritance.

Note: Use new compiler (Code blocks or Dev C++)  to run these C++ programs. Old  Turbo C compiler does not supports some new features of C++. If you want to run these programs on old Turbo C++ compiler use  <iostream.h>  instead of  <iostream>  , do not use (  using namespace std;  ) , use {  getch();  } to hold run-time screen , use  void main()  instead of  int main()  . 1 1 2 1 1 2 3 2 1 1 2 3 4 3 2 1 #include<iostream> using namespace std; class xyz {   public:    void display()     {      int  i, j, k, l, x=3;             for(i=1; i<=4; i++)       {        for(j=0; j<=x; j++)          cout <<" ";                  for(k=1; k<=...
