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
std::vector (for T other than bool) meets the requirements of Container, AllocatorAwareContainer (since C++11), SequenceContainer, ContiguousContainer (since C++17) and ReversibleContainer. Member functions of std::vector are constexpr: it is possible to create and use std::vector objects in the evaluation of a constant expression.

Vector in C++ STL - GeeksforGeeks
Statement vector<int> v1 = {1, 4, 2, 3, 5} initializes a vector with given values. Statement vector<int> v2(5, 9) creates a vector of size 5 where each element initialized to 9. More ways to declare and initialize vectors are discussed in this article - 8 Ways to Initialize Vector in C++.

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.

16.2 — Introduction to std::vector and list constructors
In the previous lesson 16.1 -- Introduction to containers and arrays, we introduced both containers and arrays.In this lesson, we’ll introduce the array type that we’ll be focused on for the rest of the chapter: std::vector.We’ll also solve one part of the scalability challenge we introduced last lesson.

C++ Tutorial: A Beginner’s Guide to std::vector, Part 1
The vector will store the Ts in a contiguous memory area that it will handle for you, and let you access the individual Ts simply by writing v[0], v[1], and so on, exactly like you would do for a C-style array. Note that for bigger projects it can be tedious to repeatedly write out the explicit type of the vectors.

How does c++ std::vector work? - Stack Overflow
In terms of sizing, there are two values of interest for a std::vector: size, and capacity (accessed via .size() and .capacity())..size() is the number of elements that are contained in the vector, whereas .capacity() is the number of elements that can be added to the vector, before memory will be re-allocated. If you .push_back() an element, size will increase by one, up until you hit the ...
