The arrows represent flow lines which show the direction of
flow of the process.
FLOW LINES
The on page connectors allow the flowchart to be drawn
neatly, without intersecting lines. They are used in pairs – one
ON PAGE denoting the end of a step and the other the continuation. The
CONNECTOR pairs are represented by an alphabet written inside the circle.
The off page connectors are used to join symbols on another
OFF PAGE page. These connectors are also used in pairs.
CONNECTORS
Let us demonstrate all the three methods with the following simple examples.
Problem 1: Accept temperature in Centigrade and convert it to Fahrenheit.
Algorithm:
Step 1: Start.
Step 2: Accept temperature in Centigrade and store it in C.
Step 3: Calculate Fahrenheit temperature F as 9 * C / 5 + 32.
Step 4: Display F.
Step 5: Stop.
Pseudocode:
Begin
Read C
F 9 * C / 5 + 32
Output F
End
Flowchart:
Start
Accept C
F = 9 * C / 5 + 32
Display F
Stop
