Array of Vectors in C++ STL

In this article, we will learn about Array of Vectors in C++ STL with C++ code snippets. Before getting started with array of vectors we should know about the arrays and vectors in C++.

Array:-

An array is a collection of elements of the same datatype and these elements are stored in contiguous memory locations.We cannot change the size of array once we have declared it.
