Sub Topic Algorithms and Flowcharts

Summary Discussing flow chart symbols, and describing flowcharts using a

few examples



Flowcharts

A flowchart is the combination of geometric symbols connected with arrows that represent

steps in a process.

Flowchart Symbols

Note: All symbols are not necessary to have a complete flowchart.
