I can't tell you the difference between those specific versions but most of what you do in Turbo C will be the same in C/C++. The big difference is that a lot of non-c-standard things will be gone, such as the clrscr method and things like that.
I would suggest getting GCC installed. If you're on Linux, it's available as a package. If you're on windows you need to get a special download. I use MinGW (http://www.mingw.org/)
Not sure what questions you might have but feel free to ask them. If I can't answer them, I can hopefully point you in the right direction.
