I don't think that's possible, although I do know you can change text color somehow in C++... don't really know how, though.

How to get one char without press "Enter" ?

You mean like getch?

You mean like getch?

getch is a non standard function.

As far as getting character without enter is concerned, it cant be achieved in standard C. Try looking at your compiler documentation for more support.
