Step 3 Compare number A and B. If A is less than B, print "A is smallest" and go
to Step 5.
Step 4 Compare number A and B. If B is less than A, print "B is smallest" and go
to Step 5.
Step 5 Stop.
FLOWCHARTS
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 Flowcharts
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
(Start/Stop) of the flowchart. It usually contains the words
'Start' or 'Stop'.
It shows a process or action step. This is the
Process
most 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).
Input/ It represents material or information entering or
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.
