vector - C++ Users
Aliased as member type vector::value_type. Alloc Type of the allocator object used to define the storage allocation model. By default, the allocator class template is used, which defines the simplest memory allocation model and is value-independent. Aliased as member type vector::allocator_type. Member types

std::vector - cppreference.com
Except for the std::vector<bool> partial specialization, the elements are stored contiguously, which means that elements can be accessed not only through iterators, but also using offsets to regular pointers to elements. This means that a pointer to an element of a vector may be passed to any function that expects a pointer to an element of an array.

std::vector reference | C++ Programming Language
std::vector is a container that encapsulates dynamic size arrays. Memory The elements are stored contiguously, one after another. This means that a pointer to an element of a vector may be passed to any function that expects a pointer to an element of an array.

Vector in C++ STL - GeeksforGeeks
C++ vector is a dynamic array that stores collection of elements same type in contiguous memory. It has the ability to resize itself automatically when an element is inserted or deleted. Create a Vector. Before creating a vector, we must know that a vector is defined as the std::vector class template in the < vector > header file.. C++

c++ - Why can't I make a vector of references? - Stack Overflow
Note however that while reference_wrapper unlike the raw reference type can be "reseated", it still cannot be uninitialized, so it is not default constructible. That means that while one can construct vector<reference_wrapper<int>>{int1, int2, int3}, one still cannot have a vector with with default constructed elements: vector<reference_wrapper<int>>(5).

vector::empty - C++ Reference - cplusplus.com
The example initializes the content of the vector to a sequence of numbers (form 1 to 10). It then pops the elements one by one until it is empty and calculates their sum. Output:

std::vector - C++ - API Reference Document - API参考文档
The storage of the vector is handled automatically, being expanded and contracted as needed. Vectors usually occupy more space than static arrays, because more memory is allocated to handle future growth. This way a vector does not need to reallocate each time an element is inserted, but only when the additional memory is exhausted.

C++ Vectors - W3Schools
C++ Vector. A vector in C++ is like a resizable array. Both vectors and arrays are data structures used to store multiple elements of the same data type. The difference between an array and a vector, is that the size of an array cannot be modified (you cannot add or remove elements from an array). A vector however, can grow or shrink in size as ...

vector - C++ Users
Parameters alloc Allocator object. The container keeps and uses an internal copy of this allocator. Member type allocator_type is the internal allocator type used by the container, defined in vector as an alias of its second template parameter (Alloc). If allocator_type is an instantiation of the default allocator (which has no state), this is not relevant.
