Explanation of Corrections:

1. Program Structure: Ensured the program has a main method that serves as the entry point and used sample data for simplicity.
2. Input Data: Provided sample customer details, membership code, room type, number of rooms, and number of days.
3. Membership Discounts:
   • Added a switch-case statement to set the discount rates based on the membership code.
4. Room Type and Charges:
   • Checked the room type and calculated the bill, discount, and payable amount accordingly.
5. Printing Statements: Corrected the print statements to ensure they display the correct data and improved formatting.

Now, you can compile and run this program to see the output for the given sample data. You can replace the sample data with actual inputs to generate bills for different customers.
