I have copied the Folder containing C++ into C drive of my computer which is working with Windows Xp.But when I Double clicks on TC.EXE file, it is not working.I am having NVIDIA chipset isthat a problem

This is a pretty vague question.

Do you mean a folder containing C++ source code, and how it is not working? You can't open the source to view it, or you can execute the program?

If it's the first problem, install Geany (http://www.geany.org/), a simple light-weight text editor. I use it for everything.

If it's the second problem, you need a C++ compiler on your machine to generate an executable image, plus you may also need to reference a library specific for Windows in order for your program to compile. If you don't have a compiler installed, I recommend this: MinGW (http://www.mingw.org/).

And what is TC.exe?

Run your Turbo c++ setup again may e it's virus.My TC running accurately
