If you are interested in learning C++, you need to be aware that C++ has been evolving ever since Bjarne Stroustrup first released it in the late 1970s. A Borland compiler that supports DOS won't implement the more recent developments in the language and any C++ books written when your Borland compiler was current will also be comparatively out-of-date.

akula65 is right. You're going to have to make sure you get a book dated to match the compiler you're using. Or if you're using an old compiler like Borland, try to get a book written for it specifically.

DJGPP (gcc for DOS) even has partial support for C++11. You can only compile 32-bit programs with it, though.

I would've recommended DJGPP, but i've always had trouble using/compiling with it on anything better than Windows 98SE....

I haven't used it for anything serious yet, but so far I've had no problems compiling on DOS with RHIDE (which is a pretty neat IDE, with 132x60 text mode!). I must say the error messages are not very helpful at times but that seems to be a common problem with C++ compilers. And make sure to have coffee and cigarettes ready when compiling on a Pentium 3.

I'm doing some kind of 2D text engine, I tested it on windows 98 and I almost needed to edit nothing from the code, but It doesn't use hardware acess, just the good and old printf xD.
I know It eat alot of resource but the pong was playable 😳 (15 - 14fps pentium 233mmx) vs 800fps on a core i7


I'm doing now some window system to make it more simple to use, making some kind of a fake multitask 😁

It should work on dos if I compile itm since 99% of the code is just c ansi things...
