📋 Features

✅ Supported Integer Operations

• + Addition
• - Subtraction
• * Multiplication
• / Division (with zero division error handling)
• ^ Exponentiation (limit: exponent ≤ 15)
• % Modulus (with zero division error handling)
• ! Factorial (limit: ≤ 12, no negatives allowed)

✅ Supported Floating Point Operations

• + Addition
• - Subtraction
• * Multiplication
• / Division (with zero division error handling)

🔁 Other Functionalities

• m → Go back to the Number Type Menu
• q → Quit the calculator gracefully with a message

🧩 Enhanced User Experience (UX)

To improve the clarity and structure of the UI, a separator line (-----------------------------------------------------------) is used throughout the interface. This separator:

• Clearly distinguishes between input sections, results, and menus
• Creates a clean and organized view
• Makes it easier for users to follow the flow of operations

💡 Sample Usage Flow

Welcome to MIPS-Based Calculator

-----------------------------------------------------------

On which of the following do you want to perform operations.
i [Integers]
f [Floating Numbers]

User input → i

Enter Operator for performing corresponding operation for integers:

+ [Addition]
- [Subtraction]
...
q [Quit]

User input → +

Enter the first argument.
10
Enter the second argument.
20
The sum is 30
