I figure I can use the class and friend feature to pass to my game map the updated locations for my characters but I am having trouble with it. I figure from reading the book if I return the user and pc x/y coord back to the game map it can then draw them through every iteration but so far it's not been successful. Ideas or thoughts?

Thanks I also fixed a few other compiling errors but now when I run it I get my instructions then goes right away to tell me I have crashed :( No map drawings and I don't get to move and I crash. :(

you were supposed to remove void and ints in the last do-while loop..
James Turnham (29)
I changed a few things including removing the void and ints from the do while loop but it's not even drawing the map for me. This is the part that I am not understanding at all. I am pretty sure that I am supposed to return values for the functions so the program knows how to draw them but I can't figure out how.
