Exercise 2

Q1. Find the sum of the numbers in each set.

You are given hundred numbers divided in ten sets in the following order.

Set 1: 1-10

Set 2: 11-20

Set 3: 21-30

…

Set 10: 91-100

You have to draw a flowchart that will print the sum of each set.

Solution

To solve this problem we have to apply the concept of loop which was covered in exercise-1.

Algorithm in simple English

1. Initialize count = 1 and i = 1 (PROCESS)
2. Check if i is less than or equal to 10 (DECISION)
   if YES then perform step 3
   else STOP
3. Set sum = 0 and j = 1 (PROCESS)
4. Check if j is less than or equal to 10 (DECISION)
   if YES then perform step 5
   else perform step 9
5. Add count to sum
   sum = sum + count (PROCESS)
6. Increment count by 1
   count = count + 1 (PROCESS)
7. Increment j by 1
   j = j + 1 (PROCESS)
8. Go to Step 4
9. Print sum (I/O)
10. Increment i by 1
    i = i + 1 (PROCESS)
11. Go to Step 2
