Question

C++ TrainStation Program

Create a function called searchForSchedules that will:

- prompt a user to enter a scheduleId

- search for arrival and departure times of trains based on a trains ID number

Create a function called editSchedules that will:

- allow the user to edit the fields for a given schedule that is in the linked list.

- the program must prompt the user to enter the scheduleId as the key to find the schedule to edit. Print a message if the schedule is not found in the linked list.

- for simplicity, the program may re-prompt the user to re-enter all of the fields associated with the given schedule; however, it must reuse the scheduleId value
