Maintain the direction of the flow from left to right or top to bottom.

Only one flow line should come out from a process symbol.
Ensure that only one flow line should enter a decision symbol, but two flow lines should leave the

They assist in detecting errors or inefficiencies early in the design or problem-solving stage.
Let us understand how some simple flowcharts are made.

Example 1: Flowchart to calculate simple interest.

Start

Read P for Principal
r for rate
t for time

Calculate
SI = (P * r * t)/100

Print SI
