Multi Thread Programming ?

Huh? What was that? You want me to do your homework?

Try to [google] Visual C++ Express Edition, Wikipedia, and threads.

For starters you should check the Win32 Thread API. If you have seperate data that each thread is operating on you shouldn't run into any issues with 4 threads. If they all have to work on the same data you will run into problems.

CreateThread

At the bottom of that page there is a link to example code showing how to create
threads.

Thanks friends,
I'm sorry.
I don't wish you to solve my Homework!
I wanna only some information about this.

If you want threading to work on multiple operating systems/platforms, you might want to take a look at Boost.Threads.

He did say he was using Visual Studio 6, so I would assume that he only needed threads on windows.

Certainly, but the requirements for his program are not Windows-specific. Besides, Boost.Threads encourages proper use of threads.

Even so he'd probably be far better off using boost threads over the rather ugly WIN API. It never hurts to write your code in a platform independent way plus boost's threading implementation shields you from a lot of the ugly very low-level fiddling you'd have to do if you were to use the raw WIN API.

I ran through a lot of problems with trying to learn and implement my first multithreaded programs. In the end, after struggling to get Boost to work, Boost.Thread is what I wound up using. I think that Boost's thread library offers a much clearner, more abstract way to do threading, allowing you to concentrate on the problem at hand instead of figuring out how to make your specific classes and such work with some other lower-level library. There is also a .msi installer for all of Boost (which would have made the job installing Boost a lot easier for me :P) Just go to http://www.boost-consulting.com/ and follow the download link to get the installer.
