Program with C++

To write a program with C++ (the most powerful programming language), you will need only a compiler and knowledge of how to use it. There are three popular free compilers available, each of which with their own negative attributes, first is GNU C++, it is very difficult to install, and can only compile console (text based) programs, second is Dev C++, I recommend this for beginners since it has full windows functionality and is very easy to install, it is effective and easy to use, I just don’t prefer it, because of its Windows 95 like theme. My personal favorite is MS Visual C++ Express Edition, however it is difficult to install and the programs made with it aren’t easily transferred to other systems, esp. other operating systems. I recommend downloading and installing Dev C++, I have used it with no viruses or other problems; however I am not responsible for damage caused by any program or tutorial on this site, use at your own risk. This tutorial will be made and tested with Dev C++ that can be downloaded from this site.

Download Dev C++ - Run and Install, just keep clicking next

To get started, go to –File –New –Project –Click Console App & Name Your Project –OK –Save

On the left-hand white box double-click Project, then main, delete the text and type this:

#include <iostream>

using namespace std;

int main()

{

    cout <<"Game Over!\n\n";

    system("PAUSE");

    return 0;

}

Go to –Execute –Compile & Run

Now You Have A Very Simple Program That Says “GAME OVER!”!!!

And Now For The Explanation

#include <iostream> - really don’t know, just that certain include files such as “iostream” allow your program to do certain things. Use “iostream” for input/output, “math” for calculations.

using namespace std; - tells the compiler what include library to use, in this case std (standard).

int main() – a function, used to organize the program, everything between the brackets is the “main” function

{

    cout <<"Game Over!\n\n"; - send the text “Game Over!” to the screen “\n” is like pressing the ENTER button

    system("PAUSE"); - remove this and see what happens, your program will run, but you will never see it because it will close before you see the text, basically this tells “system”(Your Program) to PAUSE and wait for input.

    return 0; - tells the computer that the function “main” ran successfully, look at “int” in front of main(), this is a variable, now that variable is equal to 0, when main equals 0 the computer knows that the program ran successfully.

}

Now, if you like programming and being a nerd you can experiment with this code, also if you understand this then you will recognize the source code of any major application, Windows’ OS, any Xbox Game, PS2/3 Game, you name it, everything is written in either C, C++, C#. However, internet source code is what you see on MySpace, it is either Java or HTML. C++ is much more complex, faster, and more powerful. More advanced code and tutorials to come. If you have any problems or comments, I’d be glad to hear from you on myspace or e-mail.
