Write the flowchart for the programming problem described below and then develop pseudocode to implement the solution. The program simulates a restaurant ordering system where customers can purchase multiple items—Yum Yum Burger, Grease Yum Fries, and Soda Yum—each with specified prices. The system should allow the user to select any quantity of these items in a single order and enable multiple orders with the option to terminate the process. The program calculates the total cost of the items, applies a 6% sales tax, and displays a receipt summarizing the total purchase. The flow should incorporate decision-making and repetition structures to handle multiple items and orders efficiently.

The goal of this programming task is to create a system that accurately processes customer orders at a restaurant, considering multiple items, quantities, and multiple transactions. To achieve this, the program must utilize decision-making structures such as if-else statements and loops to allow customers to add various items to their order, decide when to finalize a single order, and choose whether to start a new transaction. The core challenge involves looping through order entries, capturing quantities, calculating subtotal costs, and applying taxes, then displaying the total amount in a receipt format.

The flowchart begins with a start node, then proceeds to initialize all relevant variables, including flags for controlling the order processes (e.g., endOrder and endProgram flags), accumulators for each menu item (totalBurger, totalFry, totalSoda), overall total, tax, and subtotal. The outer loop governs whether the program continues to process new orders, prompting the user to begin a new transaction or terminate the program. Inside this, an inner loop manages the order placement process, where the user is continuously prompted to select menu items until they decide to conclude their current order.

Within this inner loop, the system displays menu options and prompts the user for a selection. Using decision structures, the system determines which item the user wants to purchase. The system then calls the appropriate procedure to get the quantity and update the total cost for that item. After each addition, the user is asked whether to end the current order or continue adding more items. If the user opts to end the order, the system calculates the total cost, including sales tax, and displays a receipt with the total amount. The procedure for calculating totals involves summing item costs, computing the 6% sales tax, and adding it to the subtotal.

Once the receipt is printed, the program asks whether the user wishes to start a new order or end the program entirely. When the user chooses to end the program, the process terminates; otherwise, the system resets variables and begins a new transaction cycle. The pseudocode structure emphasizes modular design, with procedures handling specific tasks such as getting item quantities, resetting variables, and calculating totals. This structure facilitates readability, maintainability, and scalability of the code, especially when adding new menu items or adjusting prices.
