RE: [Dev-C++] recursion

[Per W. <pw...@ia...>]

Walking a tree - or in this case traversing a directory structure - is a
very simple operation, where there isn't really any practical differences
between recursive or iterative solutions.

You need very little state information to know where to continue with
next step of the algorithm.
