You need to remove the previous value before printing the new one. There are several ways to do this

  • clear the screen - this causes flicker. Don't do it
  • print spaces in the background colour where the old value is - better
  • print the old value in the background colour - best

Whatever method you use, only write to the screen when a value changes
