Yes, but I was refering to native (C-style) strings, as in: BOOST_FOREACH(char ch, "hello world")
This is a good opportunity to ask: what does this do?
char const a[] = { 0, 1, 2 };
Or for extra fun, drop the 0.
BOOST_FOREACH( int x, a ) { std::cout << x << std::end; }
The short answer is: it is consistent with how Boost.Range handles it. The longer answer is that it is treated as a null-terminated string. In the first case, the loop immediately terminates and in the second, behavior is undefined -- you read off the end of the array because it is not null-terminated. I think this is OK. If you think this is a problem, you should discuss it with Thorsten. Whatever we decide, FOREACH and Range should be consistent. -- Eric Niebler Boost Consulting www.boost-consulting.com
