Ok, I need to know how to code a couple things in DOS based c++. First, I need to know how to add images and take responses from the keyboard (the up, down, left, right keypad.) Second I need to know how to terminate the program is something is true. And last I could use some help with a simple 2-d overhead engine for a RPG-type game in OOP. Thanks.
