PROGRAM 28

Object

Write a program that inputs the grade of a student and prints a message accordingly.

Algorithm

1. Declare character variable grade.
2. Read grade (and consider it as switch variable).
3. IF switch variable = ‘A’
   • Write “An Excellent Achievement!”
   • IF switch variable = ‘B’
     • Write “Good! Keep it up.”
   • IF switch variable = ‘C’
     • Write “Fair! You still need to concentrate.”
   • IF switch variable = ‘D’
     • Write “Poor Grade! Better work hard.”
   • ELSE
     • Write “Sorry, you have failed.”
4. Exit.
