A bulls and cows game.I am still working on this. Trying to add some more functionality.

I know the variable names are quite big. But I think that makes it easier to understand the program without comments.

I am new to C++. So, if you can suggest any improvements, then please do so.

One more thing, from my experience, Indian authors tend to provide knowledge based on TurboC which sucks. So, anyone going for a C++ course, please get a book suggested above, and then be sure to read professional C++ by Solter and Kleper (Wrox international). It rocks.
