Flowcharts

A flowchart is a diagram that represents a set of instructions. Flowcharts normally use standard symbols to represent the different types of instructions. These symbols are used to construct the flowchart and show the step-by-step solution to the problem.

Common flowchart symbols

The symbols in a flowchart are 'Start/Stop', 'Process', 'Decision', 'Input or Output', 'Connector' and 'Direction of flow'.
