Flowcharts

One way of representing algorithms is to use flow charts, also called flow diagrams. They are a useful way of planning how a computer program might work, and show others your thinking.

A flow chart shows the key points in an algorithm:

• the start and end
• the order in which the sequences of instructions are performed
• the points where inputs and outputs occur
• the points where decisions are made about what to do next

A sequence of many instructions that does not involve any of these key points may be represented as a single rectangular box.
