random number generator and function
I know my code is very messy and there are alot of errors right now but i have about 3 more functions to create but im not quite sure about how to go about these. I am still learning C so any guidance would be great
//Create random number generator for the number of moves
//Create random number generator for the which vehile to move.
//Create a fuctnion that writes to the txt file
