Refresh image in command line (C++)

I want to make a game (something like theses) in C++ (Visual C++). Now a graphic game needs to refresh its picture quite often. How do I do that in command line? The only way I know is to print around 20 blank lines. This method is unefficient and quite "laggy". What I need is something fast and efficient and that cause no memory problem because the game will process a lot of data (like mouvements, scores, coins...).

Thanks.
