Question

This system tracks car traffic violation tickets, the data in this system include: car plate number, tickcl number, violation type, fine, status (paid or unpaid). The following table shows examples of such records Assume the system will be used by employees in the traffic department When the system runs, the program starts by loading the traffic violoations data from a fixed file. Then the system displays the following menu: Add a new ticket. Delete a ticket (only unpaid tickets can be deleted) Pay a ticket. Display all violation tickets. Search for tickets by car plate no. Display all tickets that are not paid yet. Exit.
