PROGRAM 64

Object

Write a program to print all even numbers from 1 to 50 with their running total.

Algorithm

1. Declare integer variables i and tot.
2. Set tot = 0.
3. Set i = 2.
4. DO
   • tot = tot + i.
   • Write i and tot.
   • i = i + 2.
   • WHILE i<=50.
   • [End of DO-WHILE loop.]
5. Exit.
