How to Write the Hello World Program in CPP

Step-by-Step Guide

1. 1

   Step 1: Get a CPP compiler.

   If you're using Windows OS, I'd suggest you to get the latest Microsoft Visual CPP.
   
   If you're running a linux distribution or Mac OS, get Code::
   Blocks or Bloodshed Dev CPP.
   
   You can obviously get them on windows too and use whichever you feel most comfortable with.

   Step 2: Open a new project file

   This means your "Hello World!" application would be running on the console and not your operating system. , Ignore this step if your compiler is not a Microsoft Visual CPP. , This statement declares that the terms we are going to use to write the program are included in the CPP library known as "iostream". , from your console.
   
   Type "int main ()" . ,, First statement in this program is
   - using namespace std;. , The last statement ends with "endl" and semi-colon.
   
   Now go to the next line and type cout << "Hello World!" endl
3. 3

   Step 3: and choose "console application" on your compiler.

   , While complicated programs would include numerous functions, this is the simplest program possible and your first program ever so it just contains the main function. ,,

5. 5

   Step 5: then first enter the following on the first line - #Insert "stdafx.h".

7. 7

   Step 7: otherwise this would be the first line)

8. 8

   Step 8: enter #include <iostream> .

9. 9
