C++ Overview

     

                                       C language is a general-purpose programming language. It is similar to c language but, the syntax of c and c++ is a little bit different. In C we use printf for display statements and scanf for accepting the input from the user but, in C++ We use cout<< for the printing statements and cin>> for accepting input from the users. So first we see the simple program of C to print Hello World.

A simple program in C++

#include<iostream.h>    //standard I/O Streams

#include<conio.h>  //MSN-DOS compiler

void main()             //execution is started from this line

{                             //starting of program body

cout<<"HELLO WORLD";//to print the text on O/P screen

getch();                   //it holds the O/P screen

}                             //ending of program body

------------------------------------------------------------------------------------------

And save with extension .cpp

for eg.

simple.cpp//simple is the name of the file and .cpp is an extension of the file.

// Is one type of comment e.g.

void main();//Execution is started from this line.There are other functions available in c but, I will teach you in the next blog.......
