The Shapes

There are 4 basic flowchart shapes:

1. The Terminator - This shape is used to start or stop the flowchart
2. The Decision - This shape is used to allow the user to make a decision (e.g. do you like pancakes? Yes or No)
3. Input/output - This shape is used to either allow the user to input something (e.g. a value) or display something to the user (e.g. an image)
4. Process - This is used to tell the computer to do something (e.g. a sum)
