GOT SECOND CLASS

Explaining Example -

In the above example:

  • If WS-MARKS-PERCENT is greater than 60, it displays "GOT FIRST CLASS".
  • If WS-MARKS-PERCENT is greater than 50 but not more than 60, it displays "GOT SECOND CLASS". So it displays "GOT SECOND CLASS".
  • If WS-MARKS-PERCENT is greater than 35 but not more than 50, it displays "GOT THIRD CLASS".
  • If WS-MARKS-PERCENT is 35 or less, it displays "FAILED".
