title: C# concert ticket, simple switch, case, and if-else
body: <p>Program Specification: The purpose of this application will be to calculate the cost for concert tickets.
  The individual ticket cost is based on where the tickets are located. Based on the number of tickets
  ordered, a percentage off discount will be applied to the total cost. Finally, if the customer is a preferred
  customer, they will receive $10 off their order</p>
