Linked List C/C++ Programs

The Linked Lists are linear data structures where the data is not stored at contiguous memory locations so we can only access the elements of the linked list in a sequential manner. Linked Lists are used to overcome the shortcoming of arrays in operations such as deletion, insertion, etc.

In this article, we will discuss some of the common practice problems on linked lists in C/C++.
