FLOWCHART
A flowchart is a type of graphical diagram that represents an algorithm. Flowcharts are used
in analysing, designing, documenting or managing a process or program in various fields.
Hence, it is correct to say that a flowchart is must for the better understanding of a
complex program.
Symbols used in Flowchart
Different symbols are used to draw different types of flowcharts. Let us discuss them.
Name Symbol Description
It is used to show the start and stop points of the
(Start/Stop) flowchart. It usually contains the words 'Start' or
'Stop'.
It shows a process or action step. This is the most
Process
common symbol used in flowcharts.
It indicates a question or branch in the process
Decision
flow. It is used when there are 2 options (Yes/No).
It represents material or information entering or
Input/Output
leaving the system, i.e., input and output.
Flow Line
(Arrow, It shows the direction in which the process flows.
Connector)
It is used as a Connector to show a jump from one
Connector point in the flowchart to another. Connectors are
(Inspection) usually labelled in pairs to show matching jump
points.
Rules to Draw Flowchart
You must follow these basic rules while drawing a flowchart:
The flowchart should be clear, neat and easy to follow.
Maintain the direction of the flow from left to right or top to bottom.
