3. Introduction
 A flowchart is a type of diagram that represents
a workflow or process.
 A flowchart can also be defined as a diagrammatic
representation of an algorithm, a step-by-step
approach to solving a task.
 It can be used to represent how programs work.
 Flow charts are used in analyzing ,designing,
documenting or managing a process or program in
various fields.

4. Advantages
 Better Communication
 Effective Analysis
 Proper Documentation
 Efficient Coding
 Proper Debugging
 Systematic Testing
 Efficient Program Maintenance

5. Symbols of Flow Chart

6. Terminator/Terminal
Represented as circles , ovals or
rounded rectangles, usually
containing the word “Start” or “End”,
or another phrase signalling the start
or end of a process , such as “submit
inquiry” or “receive product”.
Start /
End

7. Arrow
• Showing “flow of control”.
• An arrow coming from one
symbol and ending at another
symbol represents that control
passes to the symbol the arrow
points to .
• The line for the arrow can be solid
or dashed.
• The meaning of the arrow with
dashed line may differ from one
flowchart to another and can be
defined in the legend

8. Input/output
 Represented as
a parallelogram.
 Represents material or
information entering or
leaving the system, such as
customer order (input) or a
product (output).
Input/output

9. Process
• Represented as rectangles.
• Use it to represent an event
which is controlled within
the process.
• Typically this will be a step
or action which is taken.
• In most flowcharts this will be the
most frequently used symbol.
Processing

10. Decision
 Different decisions emerge
from different points of the
diamond.
 It is a decision and
branching Point.
Decision

11. Connector
 In flowcharts, this symbol is
typically small and is used as a
Connector to show a jump from one
point in the process flow to another.
Connectors are usually labeled with
capital letters (A, B, AA) to show
matching jump points. They are
handy for avoiding flow lines that
cross other shapes and flow lines.
They are also handy for jumping to
and from a sub-processes defined in
a separate area than the main
flowchart.

12. Annotation
 Indicates additional
information regarding a
step in a process.

13. Program Flowchart
 shows the sequence of
instructions in a program
or subroutine. These
instructions are followed to
procedure the needed
output
