Explain what for (char c : str) does? [duplicate]

Question

I am asking since I couldnt immediately find an answer on google, I know the answer is simple.

what does for (char c : str) {} do in a for loop?

Thank you!

Sounds like you could use a good C++ book. It it they will go over the modern changes to C++. — NathanOliver

It iterates the individual characters of str, copying each one to the (local) variable c for use in each iteration of the loop.

Based on assumptions, that's indeed what happens. Which doesn't mean that a whole boat load of other things could happen.
