The Restaurant Menu System is a simple C++ console application that simulates a restaurant ordering system. Users can browse different food categories, select menu items, view their running total, and proceed to checkout. This project was created to practice fundamental C++ programming concepts, including loops, switch statements, conditional logic, and user input/output.

• C++
• Visual Studio Code
• C++ Standard Library (iostream)

• Loops – Used do-while loops to repeatedly display the menus until the user chooses to go back or exit the program.
• Switch Statements – Used nested switch statements to navigate between the main menu and food categories.
• Conditional Statements – Used if statements to determine whether the user wants to proceed to checkout.
• Variables – Used variables to store the user's menu selections, checkout option, and total order cost.
• Boolean Variables – Used a bool variable (menu) to control when the program should continue running or terminate.
• Arithmetic Operators – Used the += operator to continuously update the total cost of the order.
• User Input and Output – Used cin for user input and cout for displaying menus and order details.

• Display the main restaurant menu with food categories.
• Allow the user to choose between Combo Meals, Snacks & Sides, or Exit.
• Display the selected category's menu.
• Let the user add food items to their order.
• Update and display the current total after each item selected.
• Allow the user to return to the main menu.
• Ask whether the user wants to proceed to checkout.
• If the user selects Yes, display the final total and a thank-you message.
• If the user selects No, return to the main menu and continue ordering.
• End the program when the user checks out or selects Exit.

• How to use nested switch statements to create menu-driven programs.
• How to control program flow using do-while loops.
• How to accumulate values using arithmetic operators.
• How to use Boolean variables to manage program execution.
• How to create a simple ordering and checkout system.
• How to organize a console application with multiple menus.

• Allow users to order multiple quantities of each menu item.
• Display an itemized receipt instead of only the total.
• Add drinks and desserts as additional menu categories.
• Validate user input to prevent invalid entries.
• Implement functions to reduce repeated code.
• Add payment processing and calculate change.
• Save order history using file handling.

• Step 1: Open the project in Visual Studio Code or any C++ IDE.
• Step 2: Compile the program using a C++ compiler.
• Step 3: Run the program.
• Step 4: Select a menu category.
• Step 5: Choose the food items you want to order.
• Step 6: Return to the main menu or proceed to checkout.
• Step 7: View your total and complete the order.
