Question
Write an LC-3 assembly language program that continually asks users to guess a number between 0 and 9 until they reach the correct number (which is 5). If the user enters any non-digit character, the program should output 'Invalid.'
Expert Solution
Step 1
Algorithm:
- Display a message asking the user to enter a number between 0 and 9.
- Read user input from the console.
- If the user input is a digit between 0 and 9, compare it to the correct number (which is 5).
- If the user input is not a digit between 0 and 9, display a message indicating that the input is invalid and go back to step 1.
- If the user input matches the correct number, display a message congratulating the user and exit the program.
- If the user input does not match the correct number, display a message indicating that the guess was incorrect and go back to step 1.
