Since space for a trailing null is required, the minimum "capacity" is currently 1.
The maximum value for "size()" is then "capacity()-1". That seems a little wierd. Should the trailing null be counted in "capacity?"
This is a good point. At the moment fixed_string< n >::capacity() == n. It would therefore make sense that this be changed so that either:
[1] fixed_string< n >::capacity() == n - 1 -- this would seem counter-intuitive, as fixed_string< 1 > would not be able to store any characters!
Same goes for char[1], if you assume the string is NUL-terminated.
[2] change CharT str[ n ] to CharT str[ n + 1 ] -- i.e. add an extra character for the trailing null. This would make more sense, as it is similar to: char * str = new char[ s.length() + 1 ];
I personally but a vote for solution 2, but what do other people think?
I vote for #1, because it makes the char[] -> fixed_string<n> transition easier. meeroh -- If this message helped you, consider buying an item from my wish list: <http://web.meeroh.org/wishlist>
