Every time you call strlen(), it works for O(len), so your code works for O(n^2).
And please, format your code. It's really hard to read it.

Doesn't Optimizer change the code to a way you said ? I thought c++ optimizer have such things that can detect unchanged values in loops and doesn't recalculate them every time for conditions.
