C++ indexed set
WebMultisets are containers that store elements following a specific order, and where multiple elements can have equivalent values. In a multiset, the value of an element also identifies it (the value is itself the key, of type T).The value of the elements in a multiset cannot be modified once in the container (the elements are always const), but they can be inserted … Web*Note: All iterators in an unordered_set point to const elements. Whether the const_ member type is the same type as its non-const_ counterpart depends on the particular library implementation, but programs should not rely on them being different to overload functions: const_iterator is more generic, since iterator is always convertible to it. The …
