Students in India typically start their Development exposure through Tubo C/C++, which I must confess is a pretty old and obsolete development tool.

I would rather recommend using atleast GCC fow Windows, or VC/VC++.

In any case, if you need TC/TC++ compiler, you can download it from below. Just unzip the file into any drive on your harddisk. Rememeber, to set the Directories for TC properly available at:
Tools->Options->Directories

Without those settings pointing to correct paths, you would have trouble compiling any program.
