DEFINING FLOWCHARTS
A flowchart is a type of graphical diagram that represents an algorithm. It is a set of instructions
that can be followed to perform a specific task, workflow or process. This diagrammatic
representation illustrates a solution model to a given problem. Flowcharts are used in analysing,
designing, documenting or managing a process or program in various fields.
Flowcharts show the sequence of instructions in a single program. They play a vital role in
the field of programming. These are helpful in understanding the logic of complicated and
lengthy problems. Once a flowchart is drawn, it becomes easy to write the program in any
high-level language. Often we see that flowcharts are helpful in explaining the program to
others. Hence, it is correct to say that a flowchart is must for the better understanding of a
complex program.
Symbols used in Flowcharts
Different symbols are used to draw different types of flowcharts. Let us discuss them.
Symbol Name Description
It is used to show the start and stop points of the flowchart.
(Start/Stop)
It usually contains the words 'Start' or 'Stop'.
It shows a process or action step. This is the most common
Process
symbol used in flowcharts.
It indicates a question or branch in the process flow. It is
Decision
used when there are 2 options (Yes/No).
It represents material or information entering or leaving the
Input/Output
system, i.e., input and output.
Flow Line
(Arrow, It shows the direction in which the process flows.
Connector)
It is small and is used as a Connector to show a jump from
Connector
one point in the flowchart to another. Connectors are usually
(Inspection)
labelled in pairs to show matching jump points.
Rules to Draw Flowcharts
You must follow these basic rules while drawing a flowchart:
The flowchart should be clear, neat and easy to follow.
