An example of string is the italian word "più". Here I can visually count 3 chars: p, i and ù. But if I use "più".size() the result is 4
std::string ppp = "più"; size_t sss = ppp.size(); here sss is 4. L. On Mar 21, 2013, at 9:48 AM, Luther Baker <lutherba...@gmail.com> wrote: > I don't think your example makes sense.
