It doesnt but 21.3.2 does say they conform to sequence containers
which unfortunantley arent all arrays either.
Then also doesnt this apply to using &mixed[0] and
&mixed[mixed.length()]
Doesn't WHAT apply? The overloaded operator[] returns a reference.
You can take the address of it to get the address of the referred
object.
Why can't you simply use 'transform'?
Because I was trying to find out how useful facets are. Would be nice
for a simple tolower/toupper functions in the stl that just worked on
strings :-)
Point is moot now though - its an old compiler and doesn support
locale's anyway
std::transform(mixed.begin(), mixed.end(), mixed.begin(),
tolower);
? Just curious. You can of course write your own 'tolower' that
would use your specific facet, can't you?
I was looking for something already in the STL so that it would be
more efficent than anything I could write.
You're essentially spending your precious time trying to find some
elusive solution (which may or may not exist) for the sake of some
performance problem you may or may not even have. Does that pretty
much sum up what you're trying to do here?
