First C++ program - Hello word print - My CS Tutorial

First C++ program

In this tutorial, we will learn how programs are writte in the C++ language. And how they are compile and run.

You open the software where you write a program as turboC++ and write the code which are as...

We can use other object for this program which are as..

[Write a program that display a message (Hello word) on to the screen.]

#include<iostream.h>

#include<conio.h>

Int main()

 cout<<"\n Hello,welcome to computer zone.";

cout<<"\n My name is Harsh Chauhan.";

cout<<"\n this is my first program of C++ language.";
return (0);
