A data structure provides a way of organizing and storing data in a computer. Different types of data require different way of storage and representation. For example, you will need an array to store a unique-id for students of your college, you want that id to be updated automatically when a new student is added. This is what data structure provides. It provides a way to store and access different types of data. Array, Linked List, Stack, Queue, Tree, Graph etc are different data structures that stores the data in a particular way so that we can access and use the data efficiently. In this course, we will learn in detail what a data structure is, which are the different types of data structures, what operations they support and how we can create them using C++.
