How to represent a recursive function with a flowchart?

Question

I need to represent a recursive function in a flowchart. My problem is that I don’t know how to indicate that a function can call itself on several elements at a time (for example, for a function that scans charts). Anyone have any suggestion?

Answer 1

In a flowchart, you usually don’t add a few calls for things like loops, you just indicate that the code can repeat until the condition is met. Thus, for a recursive function, this would be similar: the base case is an ordinary step, and the recursive step coincides with the loop. See this for an example.
