I am learning cpp, and know there are several functions to plot at the screen with. What is the most common one, which I can find in turbo c++? How do I use it?

Please send me an easy-understood example to my mail too:

Actually not true.  Standard C++ contains no features at all for dealing with graphics.  In fact standard C++ does not even assume that there progam is running on a computer with a monitor.  Standard C/C++ only assumes that there is a text based output device, this coudl be a screen, but it could be a text file, a teletype, a punch card hole punch etc.  so it has no support for graphics.

If you want to have graphics you have to use non-standard (non-portable) procedures.   Turbo C++ may provide provide procedures like this, I don't know, but they are not really part of C++.

Well, thanks! But do you know if there are any more "common" used functions - which follows the most compilors?

Do you know how to use any of them?

Do you have a tiny library for me, with a "plot" function as explained?

If you could mail me one with an example of how to use it I'll give you the 100 points and accept it as an answer!

Nope.  This is because this must vary increadibly from one OS to another and from one computer design to another.  I have don graphics work on 3 platforms and there was NO similarity what-so-ever.

Turbo-C might very well have procedures for performing grphics, but I asure you you won't be able to port them to other OSs or ciompilers without significant changes.

If you can't find any functions that are with Turbo-C you can use the DOS video services, but this is a lot of work and requires a little knowledge of assembly.

If you want to use graphics, Allegro is an OK library. It's portable from what I understand, and can be found on

OK, hope it'll work.

Following the TC++ comes some libraries, and the putpixel function is there. I managed to use it and am satisfied actually. Thanks anyway!
