Rules to Draw Flowcharts
You must follow these basic rules while drawing a flowchart:
The flowchart should be clear, neat and easy to follow.
The direction of flow should be maintained from left to right or top to bottom.
Only one flow line should come out from a process symbol.
The flowchart should have a logical start and end.
Advantages of Flowcharts
Flowcharts provide the following advantages:
It provides a better understanding of a problem.
It facilitates a programmer to analyse the problem in detail.
Let us understand how some simple flowcharts are made.
Example 1: Flowchart to drink a glass of Example 2: Flowchart to calculate
cold water. simple interest.
Start Start
Go to the kitchen
Read P for Principal
r for rate
Take a clean glass
t for time
Take out a water bottle
from the refrigerator Calculate
SI = (P * r * t)/100)
Pour the water into
the glass
Print SI
Drink the water
Fill the bottle and keep it
Stop
back in the refrigerator

PROGRAMMING
A set of problem-solving techniques that represents problems and their solutions
in ways that a computer could also execute is known as Computational thinking.
A computer can only work using step-by-step instructions given by us. Giving these
step-by-step instructions to the computer is called programming.
