im supposed to build a simple traffic control program.. i'm done but i kno its full of errors it runs but not the results i want.. can someone please help me implement some pointers or string manipulation into the code.. i'm having problems with that.. the code is completely commented, so you may get an idea of the results desired

i've done a course on data structures last semester. got a b-.. i took your advice and and got it back down to a one dimensional and it wors pretty fine now.. thanks alot kbw..
i'd just love to use a few pointers in there to.. i try to make the array a string pointer but its an error.. seems i have a bit more research to do but thanks alot..
