Hi, I'm making a maze game in DOS and was wondering how I could make it so the player can not go through the wall's. The wall's are just the double line character's printed on the screen.

//These are the Wall's
printf("%c%c%c%c%c%c%c%c%c%c%c",185,186,187,188,20 0,201,202,203,204,205,206);

Thanks,
