One of the two most common tools in algorithm design is the flowchart.
Flowchart
A flowchart is the graphical representation of an algorithm. It can also be said that it is the detailed representation in graphic form of how the steps must be carried out in the computer to produce results.
This graphic representation occurs when various symbols (indicating different processes on the computer) are related to each other by lines that indicate the order in which the processes must be executed. The symbols used have been standardized by the American Standards Institute (ANSI):
Recommendations for the design of Flowcharts
- Only horizontal and/or vertical flow lines should be used.
- Crossing lines should be avoided using the connectors.
- Connectors should be used only when necessary.
- There should be no flow lines unconnected.
- Symbols should be drawn so that they can be read from top to bottom and from left to right.
- All text written within a symbol must be written clearly, avoiding the use of many words.
