Array: An array is a collection of elements stored in contiguous memory locations. It allows for efficient random access to its elements.
For Loop: A for loop is a control flow statement that allows you to repeatedly execute a block of code based on a specified condition. It is commonly used for traversing arrays or other data structures.
Linked List: A linked list is a linear data structure where each element (node) contains both data and a reference to the next node. It provides dynamic memory allocation and efficient insertion/deletion operations.
