Structure of Program

Hello Friends,
Today i am sharing the structure of program with all of you.
/*This Program prints Hello World on screen*/
#include<iostream>
int main (){
cout<<"Hello World";
return 0;
}

• 1. /* This Program....*/

            The symbols /* and */ used for comment.
           This Comments are ignored by compiler and are used to provide useful information about       
           program to humans who use it.

• 2. #include <iostream.h>

   This is a preprocessor command which tells compiler to include iostream.h file.

• 3. using namepace std;

   All the elements of the standard C++ library are declared within what is called a namespace, the namespace with the name std. So in order to access its functionality we declare with this expression that we will be using these entities.

• 4. main ()

C++ programs consist of one or more functions. There must be one and only one function called main.

• 5. {}

braces surround the body of the function,which may have one or more instructions/statements.

• 6. Cout<<

it is a library function that is used to print data on the user screen.

• 7. "Hello World" is a string that will be displayed on user screen.

• 8.return 0; return the value zero to the operating system.

I hope you like it .
Thank You

Introduction To C++

Hello Friends,
Today i am starting with the introduction . C++ is a general purpose,case sensitive,free-form programming language that supports procedural,and object oriented.

Object-Oriented Programming
C++ fully supports object-oriented programming,including the four pillars of object-oriented development:
-Encapsulation
-Data Hiding
-Inheritance
-Polymorphism

Use Of C++
C++ is used by hundreds of thousands of programmers in essentially every application domain.
Anyone who has used either an Apple Macintosh or a PC running Windows has indirectly used C++.
Amazon.com , Facebook , Google , HP , IBM , Microsoft & many more companies uses C++ language
