Using C#

Create a C# application using an array that prompts a user to enter an appointment to reserve the slot. There are morning appointments or afternoon appointments (the user will input either "morning" or "afternoon"). There should be only 3 morning slots and 3 afternoon slots available for the user to reserve. If there isn't a slot available, show a message that tells the user that the appointment isn't available. Some test cases (shown below) should be run in one execution.

Test cases:
