It provides a better understanding of a problem.
It facilitates a programmer to analyse the problem in detail. Example 2: Flowchart to add
Let us understand how some simple flowcharts are made. first 100 natural numbers.
Example 1: Flowchart to calculate simple interest. Start
Start
Sum = 0
N = 0
Read P for Principal
r for rate
t for time N = N + 1
Sum = Sum + N
Calculate
SI = (P * r * t)/100
Is
Print SI No N >= 100?
Yes
