Well I'm currently working on a Stacks program using the vector class. The program operates for a parking lot business whereby it enters license plate numbers of income cars into the stack, while that is done, a ticket number (Id) is provided.
The situation is when a customer wants to cash out, the ticket Id is provided and the program removes license plates stored at the top of the stack until the id matches for that corresponding license plate and stored in a new stack. I stumble on the issue of removing the license plate number checking out and restoring back the other elements into the original stack with its corresponding Id number. Can anyone help me?
