I need help refactoring this code. I need to take the parts that are all under main and make separate functions. PLEASE use call-by-reference when possible! Here is a list of the different functions: menu, type of flight, route, wind speed, and final display. After refactored I need to add a random number generator using srand and have it be displayed as the flight ID: this number must be five digits long from 00001-99999. All of the leading zeros must be printed. Thanks
