What Is Data Structure in C Types?

A data structure is a way of organizing and storing data in a computer’s memory. It allows efficient access, manipulation, and organization of data. In the C programming language, there are several types of data structures that can be used to represent different types of data.


An array is a collection of elements of the same type stored in contiguous memory locations. It provides efficient random access to its elements using an index. In C, arrays are declared using square brackets [] and can store fixed-size sequences of elements.


A structure is a user-defined data type that allows you to group together variables of different types under one name. It enables you to create complex data structures by combining primitive data types. Structures are declared using the struct keyword in C.

Linked Lists

A linked list is a dynamic data structure that consists of nodes linked together via pointers. Each node contains a value and a pointer to the next node in the list. Linked lists provide efficient insertion and deletion at any position but have slower random access compared to arrays.


A stack is an abstract data type that follows the Last-In-First-Out (LIFO) principle. It allows insertion and deletion operations only at one end, called the top of the stack. Stacks can be implemented using arrays or linked lists depending on the requirements.


A queue is an abstract data type that follows the First-In-First-Out (FIFO) principle. It allows insertion at one end (rear) and deletion from the other end (front). Queues can also be implemented using arrays or linked lists.


A tree is a hierarchical data structure that consists of nodes connected by edges. Each node can have zero or more child nodes. Trees are used to represent hierarchical relationships between elements and are widely used in applications such as file systems and search algorithms.


A graph is a non-linear data structure that consists of vertices (nodes) and edges (connections between nodes). Graphs are used to represent relationships between objects and are extensively used in network analysis, social networks, and routing algorithms.


C provides various types of data structures that cater to different needs. Understanding these data structures is essential for efficient programming in C. Arrays, structures, linked lists, stacks, queues, trees, and graphs provide different ways to store and manipulate data depending on the requirements of your program.
