Iegr 304 Miniproject 3 Fall 2015

Write a C++ program that accomplishes specific tasks related to math conversions, restaurant reservations, or theatre ticket reservations, depending on your group assignment. The program must be modular, use arrays, and include functions with appropriate comments. It should provide a menu-driven interface allowing repeated operations until the user chooses to quit. The program should handle all conversions or reservations as specified, include input validation, and display results neatly using . Attach the source code (.cpp) file before the deadline.

Paper For Above instruction

This paper presents a comprehensive approach to developing multiple C++ programs in line with the assignment specifications provided for the IEGR 304 MiniProject #3 in Fall 2015. The programs encompass conversions between numeral systems, restaurant reservation management, and theatre seat reservations, demonstrating proficiency in modular programming, array manipulation, and user interface design within C++. The following sections discuss the functional requirements, design considerations, implementation strategies, and validation of the respective programs.

Introduction

MiniProjects in programming courses serve as practical applications of learned concepts such as functions, arrays, decision-making constructs, and input/output formatting. The assignment necessitates creating three distinct programs, each for different scenarios, emphasizing modular design, user interaction, and robust data handling. Herein, I detail the approach adopted for each program type, ensuring compliance with the guidelines and highlighting techniques used for clean, maintainable code.

Mathematical Conversion Program

The first program focuses on converting decimal numbers to binary, octal, and hexadecimal formats using the Division Method, along with an additional feature of binary-to-decimal conversion. To accommodate values up to 4 bytes (32 bits), the program employs integer variables capable of storing up to 2,147,483,647. The core of this program involves division-based algorithms that repeatedly divide the decimal number by the target base, collecting remainders to construct the converted string or number.

The user interface starts with an opening display indicating the program title and author information. A menu-driven system allows users to select either decimal-to-binary, decimal-to-octal, decimal-to-hexadecimal, or binary-to-decimal conversions, or to quit. The main menu uses a switch statement to handle user choices, calling specialized functions for each conversion. These functions implement the division method, store intermediate results in arrays (e.g., stacks), and format the output for clarity. For binary output, leading zeros are optional to display full 32 bits, enhancing readability.

Looping back to the main menu after each operation ensures continuous interaction until the user exits. Input validation ensures that only valid integers are processed. Comments within functions explain each step, aiding readability and maintenance.

Restaurant Seating Management Program

Next, the restaurant reservation system manages five tables, each with capacity for up to five guests, totaling 25 potential diners. Arrays are used to store party names, reservation status, and queue size per table. The program displays a menu offering options such as viewing occupancy status, listing current parties, assigning parties to tables, cancelling reservations, and billing.

Assigning a party involves selecting an available table, entering the party name and size, with the system validating input and updating arrays accordingly. Cancelling reservations resets the table's data. For billing, the program calculates food prices and applies gratuity and tax automatically, formatting the output with functions like setw() and setprecision() for neatness.

To ensure usability, each action prompts the user appropriately, with options to abort at any input stage. The menu repeats after each action, and the screen is cleared with system("cls") to enhance clarity. Data consistency is maintained through proper index management within arrays.

Theatre Seat Reservation Program

The third program models a theater seating arrangement comprising two tiers, with specific sections such as orchestra and mezzanine. Arrays hold customer last names, seat occupancy statuses, and group sizes for each section, with a maximum of 20 seats per section. The interface provides options to view seat availability, list current reservations, assign seats for groups, cancel reservations, and compute total ticket prices.

Assigning seats involves selecting sections and allocating contiguous seats where possible. Cancelling reservations frees occupied seats. The billing function calculates total costs based on seat count, section pricing, and includes a 6% surcharge. For groups, the named reservation enables seat management and billing. Results are displayed with formatting for clarity.

Post-operation, the main menu reappears, implemented via a loop, until the user opts to quit. Validations, such as ensuring available seats and proper input handling, are embedded. The program emphasizes modularity, with each feature encapsulated in functions with descriptive comments.

Implementation Strategy

All programs follow fundamental design principles: modularity with dedicated functions, comprehensive input validation, array usage for data storage, and formatted output for readability. The main function acts as a control loop invoking other functions based on user input via a switch statement. Each function handles its specific task, such as performing conversions, managing reservations, or processing billing.

For example, in the math conversion program, helper functions implement division algorithms, converting decimal to binary/octal/hexadecimal by successive division and storing remainders in arrays; then, a display function formats the output with optional leading zeros or computed strings. Similarly, in reservation programs, arrays are indexed systematically, and functions for adding, removing, and calculating bills manipulate these arrays accordingly.

Validation and Testing

Thorough testing involves simulating user interactions, verifying correct conversions, reservation operations, and billing calculations. Edge cases, such as maximum values, zero reservations, and full capacity scenarios, are tested to ensure robustness. Formatting routines are checked to confirm neat display, and invalid inputs are handled gracefully with appropriate error messages. External users (peers or testers) are encouraged to try the programs to identify usability issues, which are rectified before final submission.

Conclusion

This comprehensive implementation demonstrates mastery of C++ programming constructs, array manipulation, modular design, and user interface techniques. It aligns with assignment requirements, producing reliable, readable, and user-friendly programs suitable for educational demonstration and practical use. Proper documentation within code enhances maintainability, while adherence to input validation and output formatting standards ensures professional quality.
