What Is Structure in Data Structure With Example?

In the field of computer science, data structure refers to the way data is organized, stored, and accessed in a computer system. It is a fundamental concept that plays a crucial role in solving complex problems efficiently. One of the key components of data structure is a structure.

Understanding Structure

A structure is a user-defined composite data type that allows you to store different types of data under a single name. It enables you to group related variables together, making your code more organized and readable. In simple terms, a structure can be seen as a container that holds multiple variables of different types.

Let’s take an example to understand this better:

struct Employee {
    int id;
    char name[50];
    float salary;

The above code defines a structure called Employee. It consists of three variables: id, name, and salary. The variable id is an integer, name is an array of characters (string), and salary is a floating-point number.

Creating Variables of Structure Type

To use the defined structure, you need to create variables of that type:

struct Employee emp1;
struct Employee emp2;

In the above code snippet, we have created two variables: emp1 and emp2, both of which are of type Employee. These variables can now hold the data related to an employee, such as id, name, and salary.

Accessing Structure Members

You can access the members of a structure using the dot (.) operator. Let’s see an example:

emp1.id = 1;
strcpy(emp1.name, "John Doe");
emp1.salary = 5000.0;

In the above code snippet, we assign values to the members of emp1. The dot operator is used to access each member of the structure and assign a value to it.

Advantages of Using Structures

  • Organization: Structures help in organizing related data together, making it easier for developers to understand and maintain code.
  • Modularity: By grouping variables together, structures promote modularity in programming, allowing you to reuse and manipulate data efficiently.
  • Data Abstraction: Structures provide a way to abstract complex data types and represent them with a single name. This simplifies the overall code complexity.
  • Data Integrity: With structures, you can ensure that related data is always accessed and modified together, maintaining data integrity.


In summary, a structure in data structure is a user-defined composite data type that allows you to group different types of variables under a single name. It provides organization and modularity to your code while promoting data abstraction and integrity. Understanding structures is essential for building efficient and scalable programs that deal with complex data.

I hope this article has helped you gain a better understanding of what structure means in the context of data structures. Happy coding!
