A ContiguousContainer is a Container that stores objects in contiguous memory locations.

Requirements

The type X satisfies ContiguousContainer if

• The type X satisfies Container
• The type X supports LegacyRandomAccessIterators
• The member types X::iterator and X::const_iterator are LegacyContiguousIterators (until C++20)contiguous_iterators (since C++20)

Contiguous containers in the standard library

basic_string	stores and manipulates sequences of characters (class template)
array (C++11)	static contiguous array (class template)
vector	dynamic contiguous array (class template)
