Rewriting if elses into switch statement, i have wrote this code with if elses and need to rewrite as switch

I am working on the following piece of code for the following assignment, but i am having the hardest time to re write as a switch statement, please help me re write properly.

The ABC Community Hospital needs a program to compute and print the billing statement for each of its patient. The following table shows the fees for the various services:

The ABC Community Hospital

Room Charges per Day: Private $550.0 Semi-private $350.0 Ward $105.00

Telephone $4.50

Television $7.50

Medication $275.00

Write a class called Hospital that accepts the following indicators: • The patient’s name (First name and last name) • An integer representing the number of days the patient is in the hospital. • A single character representing the type of room the patient chooses. Room type (P/p= private, S/s means semi-private, and W/w means ward)

As part of the billing, note the following: • If a patient chooses private room, then the cost for medication is twice what is shown on the billing chart; if the patient chooses semi-private, then the cost for medication is what is shown on the billing chart; and if the patient chooses ward, then the billing cost is half what is shown on the billing chart. • A patient who chooses private room pays for television service and telephone service; a patient who chooses semi-private room pays for television service, and a patient who chooses the ward gets television and telephone services free.
