Write numbers to surface ? (Corrected)

Hi I´m a beginner at this so this might sound easy, but I can´t figure it out. I would like to write the score in a game with two players. The player info together with the score is stored in a class. To write the score to the surface I need to convert the int to a char* (I think). It works when I DON`T use the class. --- score=10; sprintf(buffer," %d",score); Draw_Text(buffer,120,580,Player1._color,lpDDSPrimary,font); --- How do I make it work using a class ?
