Warnings
Member function templates are used in all containers provided by the Standard Template Library. An
example of this feature is the constructor for multiset<Key, Compare, Allocator>, which takes two
templated iterators:
template <class InputIterator>
multiset (InputIterator, InputIterator,
const Compare& = Compare(),
const Allocator& = Allocator());
multiset also has an insert function of this type. These functions, when not restricted by compiler
limitations, allow you to use any type of input iterator as arguments. For compilers that do not
support this feature, we provide substitute functions that allow you to use an iterator obtained from
