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:

  1. Display a message asking the user to enter a number between 0 and 9.
  2. Read user input from the console.
  3. If the user input is a digit between 0 and 9, compare it to the correct number (which is 5).
  4. 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.
  5. If the user input matches the correct number, display a message congratulating the user and exit the program.
  6. 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.
