Declaration and Initialization of a Vector A vector is defined as the std::vector class template in the <vector> header file
- 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 needed To use a vector, you have to include the

1)std::vector is a sequence container that encapsulates dynamic size arrays 2)std::pmr::vector is an alias template that uses a polymorphic allocator

C++ Vector Declaration Once we include the header file, here's how we can declare a vector in C++: std::vector<T> vector_name; The type parameter <T> specifies the type of the vector It can be any primitive data type such as int, char, float, etc For example, vector<int> num; Here, num is the name of the vector Notice that we have not specified the size of the vector during the declaration
- vector - C++ Users
Instead, vector containers may allocate some extra storage to accommodate for possible growth, and thus the container may have an actual capacity greater than the storage strictly needed to contain its elements (i e , its size)
- 16. 2 — Introduction to std::vector and list constructors
Introduction to std::vector 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

- Vector of Vectors in C++ STL with Examples - GeeksforGeeks
In C++, a vector of Vectors is a two-dimensional vector with a variable number of rows, where each row is a vector Each index of a vector stores a vector that can be traversed and accessed using iterators It is similar to an Array of Vectors but with dynamic properties Syntax:
