hey, i am trying to run this program, but it's not letting me. Would you
help me, please!
Thank you!!!

//This program reads in a customer's name and time *

//they were in a parking garage. It then calculates*

//and prints out the average payment of all the *

//people, the payment each person owes, and the *

//change each person gets back. It also calculates*

//and prints out anyone that is under the average *

//payment. *
