It is possible to efficiently organise and store data using data structures in C, enabling quicker information access, modification, and retrieval. Here is a list of various C data structures that are often used: Linked Lists: Linked lists are made up of nodes, each of which has a pointer to the node after it and data. They enable efficient element insertion and deletion at any place as well as dynamic memory allocation. Last-In-First-Out (LIFO) data structures include stacks.First-In-First-Out (FIFO) data structures are called queues. Trees: Trees are node-based hierarchical data structures. Commonly used variants include binary trees and binary search trees.Graphs: Graphs have nodes (vertices) and edges connecting them. They can be applied to show intricate networks and interactions. To move through them, graph traversal techniques like depth-first search (DFS) and breadth-first search (BFS) are used. Key-value pairs are used to store data in hash tables. Each data structure has its own advantages and use cases, and understanding them is essential for effective programming and problem-solving. They employ a hash function to map keys to a specific index in an array.
