Hi, I need to iterate thru strings (For various reasons, I can't use string or vector<char> containers). I found that boost::range exactly fits the bill for me. I get all the convenience of an iterator (from as_literal.hpp). I have a piece of code char* char_s = "I am fine"; char *cp; std::size_t sz = strlen(char_s); const char* str_end1 = str_begin( char_s ) + sz; for (cp = str_begin(char_s); cp != str_end(char_s); ++cp) cout << *cp; I have couple of questions: 1. In the loop, boost::range seems to be calling strlen every iteration. This is an overhead. I was wondering if there's a way I can pass in the length myself so that boost::range would use it and avoid calling strlen(). 2. If it's not possible, is there a way for me to use iterators (boost or non-boost) over char strings?
