 |
|
In std::string there is find_first_of and find_first_not_of.
But in <algorithm> there is only first_first_of.
Why isn't there find_first_not_of in <algorithm> ?
It's a trivial code change from the implementation of find_first_of.

I would guess because you can supply a predicate to the find_first_of
algorithm that inverts the test, while string's find_first_of doesn't
have this functionality.

Because it was a different subgroup that thought up member functions
for template class string from the group that developed the Standard
Template Library. And there was very little effort at homogenizing the
Standard C++ library along the way.
