Rules to Draw Flowcharts Start
You must follow these basic rules while drawing a flowchart:
Maintain the direction of the flow from left to right or top to Read P for Principal
bottom.
r for rate
Only one flow line should come out from a process box. t for time
Only one flow line should enter a decision box, but two flow
lines should leave the decision box.
Calculate
Ensure that the flowchart has a logical start and end.
SI = (P * r * t)/100
Look at the flowchart to calculate simple interest.

to improve efficiency. They helped companies visualise
workflows and identify bottlenecks or unnecessary steps,
making it easier to streamline their operations.
SOLVING PROBLEMS USING ALGORITHMS AND
FLOWCHARTS
Some examples are given below to solve the problems using algorithms and flowcharts:
Example 1: Write an algorithm and draw a flowchart to check whether a given number is
even or odd.
Algorithm: Flowchart:
Step 1 Start. Start
Step 2 Read Number.
Step 3 Check If Number % 2 == 0 Then Read a Number
print "Number is even."
Else Is
Yes
print "Number is odd." Number%2==0? Print Number is even
Step 4 Stop.
No
Print Number is odd
