Question

Which of the STL containers store the elements contiguously in adjacent memory locations)?
(A) std::vector
(B) std::list
(C) std::map
(D) std::set​

Answer 1

Explanation:

The STL standard associative containers (set, multiset, map, multimap) allow access to elements using a key:

For set and multiset element is its own key.

For map and multimap elements are of type pair<const Key, T>. ...

set and map contain at most one element for each key.
