Structure and Union Examples

Are you new to programming and struggling to understand the concepts of structure and union? Don’t worry, in this blog post, we’ll break it down for you and provide some easy-to-understand examples. By the end of this post, you’ll have a solid understanding of how these concepts work and how they can be used in your programs. So let’s dive in!

Structure and Union : An Overview

Structures and unions are two composite data types in C and C++. They allow you to combine multiple variables of different data types into a single entity. Think of them as containers that can hold multiple pieces of data.

Topics Covered

Throughout our learning journey, we have explored the following topics:

  1. Structure
  2. Union

We have created some examples in order to gain a better understanding of these topics.

We suggest you try creating these programs on your own before going through these examples.

If you are a programming newbie, it’s helpful to start by going through each example below to see if you can understand them, and then try writing these programs on your own.


1Demonstrate the use of structures
2Demonstrate the use of unions
3Demonstrate the use of structures with pointers
4Add two complex numbers using structure
5Find the largest and smallest element in an array using structure
6Find the area and perimeter of a rectangle using structure
7Implement a queue using union

In this blog post, we covered the basics of structures and unions in C and C++. We learned that structures allow you to group variables of different data types into a single entity, while unions can hold only one member value at a time. We also provided examples to demonstrate these concepts in action.

Now that you have a good understanding of structures and unions, you can start using them in your own programs. Experiment with different data types and create your own structures and unions. The more you practice, the better you will become at utilizing these powerful data types.

If you want to delve deeper into this topic, we recommend checking out the official documentation of C or C++. There are also plenty of online tutorials and resources available that can help you gain a thorough understanding of structures and unions.

Happy coding!
