1. User Interface: Create a simple text-based user interface where users can input two numbers and select an operation (addition, subtraction, multiplication, or division). 2. Arithmetic Operations: Implement subroutines for each of the selected arithmetic operations. Ensure that the assembly program can perform addition, subtraction, multiplication, and division accurately. 3. Input and Output: Develop code to accept user input for two numbers and the desired operation. Display the result of the operation to the user. 4. Error Handling: Implement basic error handling to deal with scenarios like division by zero or invalid input. Provide clear error messages to the user. 5. Testing: Test the calculator program with various inputs to ensure it produces correct results and handles errors gracefully.
