  • Writing algorithms - Flow diagrams
    • Start / stop
      • The beginning and the end of the algorithm are put in boxes with rounded corners
    • Inputs / outputs
      • Anything that's put in or taken out of the algorithm goes in a parallelogram
    • Processes
      • General instructions, processes and calculations go in rectangles
    • Decisions
      • Decisions, 'yes' or 'no', are put in diamonds
    • Sub-routines
      • They are like sub programs, they reference other flow diagrams
    • Sequence
      • Only one way from start to end
    • Selections
      • There are multiple ways to get from start to stop
    • Iterations
      • It contains a loop that allows you to repeat a task
