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.
