Introduction of C++ Programming Language.

 

C++

What is C++?

·        C++ is a multi-paradigm programming language that supports Object-Oriented Programming (OOP).

·        C++ was developed by Danish computer scientist Bjarne Stroustrup at Bell Labs in 1983.

·        C++ is an extension of C Programming language.

Object-Oriented Approach

The approach of object-oriented is to focus on capturing the structure and behavior of information systems into small modules that combines both data and process. The main aim of Object-Oriented Design (OOD) is to improve the quality and productivity of system analysis and design by making it more usable.

Elements of OOPs.

1.     Objects

2.     Attributes

3.     Behavior

4.     Class

5.     Methods

6.     Message

Let’s begins with a Simple Program

#include<iostream>                           // header file

int main( )                                            //main function

{

  cout<<”HELLO WORLD”;             // output statements

}
