Me still learning C++ and traversing a file path string and adding each subdirectory to a vector so I can pop them off later and move back up to the root one dir at a time.

I am still figuring out why it's crashing. Been two days. I think half my code is just print statements now, all saying "here", "here now", "now running blahblah()"

This shit can make you feel so stupid sometimes. Because this has been a solved problem for half a century. Coding is definitely an exercise in tolerance for failure and frustration.

iterators are invalidated when you push/pop a vector

I'm just using "[n]" to access each element and ".size()" to make sure I don't go over. Solved it now, was an off-by-one mistake deep in some other function I didn't catch. I was trying to access an element in the vector that didn't exist yet.

I have been playing with STL's built in iterators, but still in the process of learning how to use them. Thanks for the heads up though!
