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. By function Overloading. Operator Overloading. 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 o...

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()  . #include<iostream> using namespace std; class factors {   public:   void display(int u)   {     int num = u;      int i=2,j,fact;            while(num!=0)         {                    if (num%i==0)             {               cout << i;             ...

Beginning with C++

-
What is C++ C++ is an object oriented programming language. It was developed by Bjarne Stroustrup at AT & T Bell Laboratories. C++ is a superset of C . The most important facility that C++ adds on to C are classes, inheritance, function overloading, and the operator overloading. These features enables creating of abstract data types, inherit properties from existing data types  and support polymorphism, thereby making C++ a truly Object Oriented Language. The Object Oriented feature in C++ allow programmers to build large programs with clarity extensibility and ease of maintenance, incorporating the spirit of efficiency of C. The addition of new features has transformed C from a language that currently facilitates top-down , structured design, to one that provides bottom-up, object-oriented design.   Applications of C++ C++ is a versatile language for handling very large programs. It is suitable for virtually any programming task including development of e...
