Hi guys. void reverse(string str) { string tmp;

Question

Hi guys. void reverse(string str) { string tmp;

unsigned int l = str.length();
tmp.reserve(l);
for(auto *end = &str[l-1]; *end >= str[0]; --*end) {
tmp += *end;
}
cout << tmp;
}
Is this a good way to reverse a string? Or is there a better way?
Note that I am just doing what I remember from the book(which I've just read(without any good practice) this summer), so I may have written stupid things.
Actually I don't reverse, I know. But this is just a test

Yesterday I was having a trouble with int/uint so I decided to do this.

It would be a good way if it was not undefined behaviour that fails on all architectures ever made by IBM or on any place that doesn't guarantee that char and unsigned char behave the same

But I still prefer string reversed{original.rbegin(), original.rend()}; When I want to go original
