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.

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++ 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 ...

C++ std::vector Interface Overview & Guidelines | hacking C++
vector is a so-called regular type (it behaves like int ). deep copying: copying creates a new vector object and copies all contained objects; deep assignment: all contained objects are copied from source to assignment target; deep comparison: comparing two vectors compares the contained objects; deep ownership: destroying a vector destroys all contained objects

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 ...

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.

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.

C++ Vectors – std::vector - Containers Library - MYCPLUS
This C++ program demonstrates how to access and traverse elements in a vector using various access functions.It initializes a vector ints with values from 1 to 10 and then uses four different access methods to retrieve specific elements:. at(): Safely accesses an element at a specific index, in this case, the element at index 4. front(): Returns the first element of the vector.
