与内置数组相比,array是一个种更安全、更容易使用的数组类型。与内置数组类似,array对象的大小是固定的。因此,array不支持添加和删除元素以及改变容器大小的操作。forward_list的设计目标是达到与最好的手写的单向链表数据结构相当的性能。因此,forward_list没有size操作,因为保存或计算其大小就会比手写链表多出额外的开销...
dynamic contiguous array (class template) deque double-ended queue (class template) make_array (library fundamentals TS v2) creates astd::arrayobject whose size and optionally element type are deduced from the arguments (function template)
1)std::vectoris a sequence container that encapsulates dynamic size arrays. 2)std::pmr::vectoris an alias template that uses apolymorphic allocator. The elements are stored contiguously, which means that elements can be accessed not only through iterators, but also using offsets to regular poin...

Fixed-size arrays (also called fixed-length arrays) require that the length of the array be known at the point of instantiation, and that length cannot be changed afterward. C-style arrays and std::array are both fixed-size arrays. Dynamic arrays can be resized at runtime. std::vector ...

If the size of the bitset is known at compile time, std::bitset may be used, which offers a richer set of member functions. In addition, boost::dynamic_bitset exists as an alternative to std::vector<bool>. Since its representation may be optimized, std::vector<bool> does not necessari...
