How it works...

The std::vector class is designed to be the C++ container most similar to and inter-operable with C-like arrays. A vector is a variable-sized sequence of elements, guaranteed to be stored contiguously in memory, which makes the content of a vector easily passable to a C-like function that takes a pointer to an element of an array and, usually, a size. There are many benefits of using a vector instead of C-like arrays and these benefits include:

• No direct memory management is required from the developer, as the container does this internally, allocating memory, reallocating, and releasing.

Note that a vector is intended for storing object instances. If you need to store pointers, do not store raw pointers but smart pointers. Otherwise, ...
