I/O Design for Restaurant Bill Splitting Program

Create an I/O design for the following problem statement. Hint: There should be a total of 7 variables. The output should have 6 variables – the overall bill, tip, and total and then the split amount for all three of these for each member of the party.

Problem Statement: Imagine that you and a number of friends go to a luxury restaurant, and when you ask for the bill you want to split the amount and the tip (15 percent) between all. Your program should print the amount of the bill, the tip, the total cost, and the amount each person has to pay. It should also print how much of what each person pays is for the bill and for the tip.

To design the I/O for the given problem statement, we will define the input and output variables clearly. The program will take the necessary inputs and then compute the required outputs based on those inputs.

Input Variables

1. bill_amount: The total amount of the bill (float).
2. number_of_people: The number of people in the party (integer).

Output Variables

1. tip_amount: The calculated tip amount (float).
2. total_amount: The total amount including the bill and the tip (float).
3. split_bill_per_person: The amount each person pays for the bill (float).
4. split_tip_per_person: The amount each person pays for the tip (float).
5. split_total_per_person: The total amount each person pays (float).
6. formatted_output: A formatted string that summarizes the bill, tip, total, and individual contributions (string).

I/O Design

Input

• Prompt the user to enter the total bill amount.
• Prompt the user to enter the number of people in the party.

Output

• Print the total bill amount.
• Print the calculated tip amount (15% of the bill).
• Print the total amount (bill + tip).
• Print how much each person pays for the bill.
• Print how much each person pays for the tip.
• Print the total amount each person pays.
• Print a summary of the contributions.

Example I/O Flow

Input

Enter the total bill amount: 200.00
Enter the number of people in the party: 4

Output

Total Bill Amount: $200.00
Tip Amount (15%): $30.00
Total Amount (Bill + Tip): $230.00
Each person pays for the bill: $50.00
Each person pays for the tip: $7.50
Each person pays total: $57.50

Summary:
- Total Bill: $200.00
- Total Tip: $30.00
- Total Amount: $230.00
- Amount per person for the bill: $50.00
- Amount per person for the tip: $7.50
- Total amount per person: $57.50

Implementation Notes

• Ensure to handle edge cases, such as when the number of people is zero or negative.
• Format the output to two decimal places for currency representation.
• Consider using functions to encapsulate the logic for calculating the tip, total, and splits for better readability and maintainability.
