Vector in C++

A vector is a collection of objects stored in contiguous memory locations. It functions as a dynamic array where elements can be inserted or deleted at any point in the collection. This dynamic nature allows for fast access time when searching for or manipulating specific elements of the vector. 

To use Vectors in C++, the “vector” header must be included in your program to access its related functions and methods. Once included, you can create and initialize a vector like any other standard container. Memory allocation occurs automatically as elements of the vector are added or removed throughout its lifetime.
