Depends, if you mean using the Win32 API, then it's easily possible. AFAIK it's not possible to set the font size on the console through just using C++ code.

Use some graphics library.

>Use some graphics library.
There's not much point in recommending that, we first need to know some details before simply telling him to use a graphics library. If he's using the Win32 API, he can simply use CreateFont and use the returned object with the window HDC.

If he plans on doing this with a console window, then there's problems.

I am working on UNIX, and using CC to compile the code.

Wouldn't it be terminal dependent? something to do with termcap settings? (Just guessing, its been 15 or so years since I worked with *nix).

Then, i believe you can't use graphics library. Only for console applications.

its so easy!!!!

Ok smartass if its so easy then prey tell us the answer.

It's the I-know-the-answer-but-I-won't-tell syndrome.
It generally happens to people who suffer from I-don't-know-the-answer

Don't be too hard on him...
