Question

For this problem, do the following:

  1. Analyse and develop the specifications – INPUT and OUTPUT 
  2. Write a solution to the problem – PSEUDOCODE and FLOWCHART 


Create a program to compute for the sum of the first n numbers, where n is a positive integer. The user enters a number and the program displays the sum of numbers from 1 to that number. The program should make sure that the user enters a positive integer before displaying the result.

 

The attached picture is not related to the problem but an example only of what the pseudocode and flowchart will be. 

Find the sum of 5 numbers
Flowchart
Start
Algorithm in simple English
1. Initialize sum = 0 and
count = 0 (PROCESS)
2. Enter n (I/O)
3. Find sum + n and assign it to
sum and then increment
count by 1 (PROCESS)
4. Is count < 5 (DECISION)
if YES go to step 2
else
Print sum (1/0)
sum = 0
count = 0
Enter n
sum = sum +n
count = count + 1
Is
Print sum
count <
NO
5
YES
Stop
