Teach yourself C++ Lesson 1 hello world in detail

Today we are going to take a traditional approach to programming and start with what is typically the simplest program to perform in computer programming. The Hello World program has been used since 1972, when it first appeared in Tutorial Introduction to the Language B. It's purpose is to check that a new compiler setup is working correctly, and as a way to teach new users the simplest syntax and program structure needed to get a useful result from your program. C++ was first invented in 1983 at Bell Labs as an enhancement to the already existing C language. C itself was developed between 1969 and 1973. As you've begun to realise both these languages have long histories and are still in active use today remaining among the worlds most popular programming languages.

This tutorial, is going to be split into three sections, the first section, is where we type in the source code, to get a feel for it.

The second part is going to deal with the specific commands of that source code so you get a picture of what is going on.

The third part is going to deal with the inevitable jargon used throughout this tutorial. These will include words like compiler, preprocessor, header files, etc.

I don't know if it's my computer, but every time I try using Visual Studio, it won't debug and I use codeblocks and the program comes out as a Trojan. What gives?

[dcforemanuk]

it is a false positive or your pc in infected with something, contact your anti-virus provider.

I use Microsoft Visual Studio with my DarkGDK tutorials, and there's several advantages with code::blocks.

1) Windows, Linux, and Mac users can use code::blocks

2) Code::blocks is completely free and open source

3) I may get into OpenGL and multi-platform coding in the future.

4) I like code::blocks!

5) I always try to support quality open source software.

No you don't. I have used visual studio to write this code successfully without using #include stdafx.h. I did it today actually using Visual studio 2012. However the console window closes very quickly so one must add "cin.get();" before return 0. The causes the window to stay up and makes you press enter to close the window

[MasterJkpatrick]

When you use visual studio you must also put in

#include "stdafx.h"

before the iostream

I'm sure you get these all the time, but I felt like I had to send it. Your video tutorials are great, and I have seen that when people comment with questions you answer them. You both try to explain everything in depth in the videos, and help people through problems in comments. That is absolutely admirable. I am going to post links to your videos just for the simple fact that it seems that you really are out to help people and I really respect that. Take care, and good luck!

It's an old school technology called mono. This means it will only play through a single speaker. As there's only one person talking stereo isn't really needed. At the time my equipment was set to record mono, so mono is what you've got. My later tutorials receive upgraded audio equipment and these play in stereo.
