It provides a better understanding of a problem. Sum = 0

It facilitates a programmer to analyse the problem in detail.
Let us understand how some simple flowcharts are made. N = 0
Example 1: Flowchart to calculate simple interest.

N = N + 1
Start

Sum = Sum + N
Read P for Principal
r for rate
t for time Is

N > 100?
Calculate No
SI = (P * r * t)/100
Yes

Print SI Print Sum
