So I am working on a Traffic Simulator and I am having a fair bit of trouble with it. I need the menu to display, user chooses the option enters a value for the option and then either it loops with the menu again and they can set other options. Or should I have pop up dialog windows that allow show up immediately starting with menu option 1 and progressing from there. Anyway have a look and see where and what is wrong and what I need to do to fix it, so I can compile it and run it. When compiled it just needs to run from DOS and use ASCII characters for the grid. - is for horizontal lanes, | is for vertical lanes and c is used to represent the cars.
