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

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 ...

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.

C++ Vector - Online Tutorials Library

Therefore, compared to array, vector consumes more memory in exchange for the ability to manage storage and grow dynamically in an efficient way. Zero sized vectors are also valid. In that case vector.begin() and vector.end() points to same location. But behavior of calling front() or back() is undefined.

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 ...

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.
