CASE labels can be ranges

Level 2: Types. IGCSE CASE matches one value. 9618 adds inclusive ranges, which is how grade boundaries are written.

Read an integer mark from 0 to 100. Output the grade:

  • 80 TO 100 → A
  • 60 TO 79 → B
  • 40 TO 59 → C
  • anything else → U

80 TO 100 includes both ends.
