Question

I am trying to make a flowchart of my program (yes I know it is the wrong order to do it:) )
and I made a desicion symbol to represent the actionsheet I display in the iPhone application. It prompts the user “Yes, No, Cancel”, so it is three options. However on all the templates/tutorials I have seen they only use “Yes” and “No” over the arrows which lead out from the desicion symbol. So could I use “Cancel” as well? If not how could I have done it otherwise?

Answer 1

You can do whatever you want with it, as long as it simplifies the meaning for your program. Decision making isn’t restricted to ‘yes’ and ‘no’.

Most of the time, flow charts are used to explain program logic to non-programmers. Your goal is to get them to understand what you program. We often use visual tools for this. You want to put all relevant information on there. If the cancel button is important to your program, put it on there. In my opinion there is no strict rule about what a flowchart should look like. Over time some basic form of flowchart has grown but you can add or remove whatever you want if it allows you to make more comprehensible charts.
