PROGRAM 50

Object

Write a program to read the marks of 5 subjects of 3 students. Find the total and percentage of each student and print it.

Algorithm

1. Declare integer variables a, b, c, d, e, t and i.
2. Declare float variable p.
3. Set i = 1.
4. Repeat WHILE i <= 3
   • Read marks of five subjects a, b, c, d and e.
   • t = a + b + c + d + e.
   • p = (t/500)*100
   • Write total marks t and percentage p.
     • i++.
   • [End of WHILE loop.]
5. Exit.
