C++ has three data types which we can use to store specific items such as List, SinglyLinkedList, and DoublyLinkedList. std::vector can be used as List , std::forward_list can be used as SinglyLinkedList, and std::list can be used as DoublyLinkedList. They both have fetching, inserting, searching, and removing operations. However, the method names they have are different with our developed data type, and we are going to discuss this in this section. In this section, we are going to discuss std::vector and std::list only, since std::forward_list is similar to std:: list.
A vector, which is like an array, is a container to store a bunch of items contiguously. However, the vector can double its size automatically if we insert a new item when its capacity has been reached. Also, vectors have many member functions that arrays don't have, and provide iterators that act like pointers but aren't.
Don't forget to include the vector header at the beginning...
