vector - C++ Users
Vectors are sequence containers representing arrays that can change in size. Just like arrays, vectors use contiguous storage locations for their elements, which means that their elements can also be accessed using offsets on regular pointers to its elements, and just as efficiently as in arrays.

Vector in C++ STL - GeeksforGeeks
Vector in C++ can be traversed using indexes in a loop. The indexes start from 0 and go up to vector size - 1. To iterate through this range, we can use a loop and determine the size of the vector using the vector size ()method. We can also use a range-based loop for simple traversal.

How does c++ std::vector work? - Stack Overflow
std::vector is a collection class in the Standard Template Library. Putting objects into a vector, taking them out, or the vector performing a resize when an item is added to a full vector all require that the class of the object support an assignment operator, a copy constructor, and move semantics.

16.2 — Introduction to std::vector and list constructors
std::vector is one of the container classes in the C++ standard containers library that implements an array. std::vector is defined in the <vector> header as a class template, with a template type parameter that defines the type of the elements. Thus, std::vector<int> declares a std::vector whose elements are of type int.

std::vector<T,Allocator>::vector - cppreference.com
Constructs a new vector from a variety of data sources, optionally using a user supplied allocator alloc. 1) The default constructor since C++11. Constructs an empty vector with a default-constructed allocator. If Allocator is not DefaultConstructible, the behavior is undefined. 2) The default constructor until C++11.
