Please help me to resolve my problem.

How to print a set of character in bold form in "c" or "c++" language.

Neither language can do this. "Bold" is a feature of your output device.

What kind of output device are you using? Is it a console window? (If so, what OS?) Is it a Windows Rich Edit control? Is it something else?

Let us know and we can give you some C++ code to do it, or point you to a tutorial or documentation on how to do it...
