This book is designed to help anyone learn the C language without any prior knowledge.
It also helped me a lot in organizing C language concepts.
The projects that were carried out in each chapter were interesting, so I was able to follow along with enjoyment until the end.
I highly recommend this book as an introductory book to the C language.
_Yoonran

It provides detailed explanations of unfamiliar terms or terms you know but don't know the meaning of.
The examples are from everyday life, so even beginners can easily approach them.
I think programming requires a lot of practice, and I liked that there were a lot of examples and projects.
I highly recommend this book to anyone who is new to or looking to review the C language! _Lee Seong-hee

Each chapter consists of concepts, examples, and projects, so I learned the concepts, read detailed explanations, and created projects based on what I learned. This helped me remember the content for a long time and identify areas where I was lacking.
I was at a loss when it came to studying the C language, but this book helped me learn it without any problems.
_Kwon Hyung-seung

As a non-major, this book is simply a blessing! It not only explains concepts I've learned in various places in an easy-to-understand manner, but also provides practical exercises for each chapter to help you master the concepts. It's packed with valuable information.
There is no better book to learn the C language in a fun and proper way.
_Kim Chan-jin

Introductory books on the C language either omit explanations or do not describe in detail the parts I was curious about.
However, this book seems to have been well-written, capturing in detail the content that readers might be curious about.
Since the projects are organized by chapter, I was able to study the advanced course without any problems.
As a computer engineering student, I highly recommend this book.
_Kwon Oh-hui

Unlike other books, this one covers even the smallest details, such as how to create files or how to write code, making it very easy to study.
I also liked the fact that the 1-minute quiz included many elements that encouraged readers to think and solve the problem, which helped them grow on their own.
And what helped me the most was doing a project at the end of each chapter to practice the concepts and grammar.
_Hwang Eul-seon

I had never learned coding before, so I was worried that it would be too difficult.
However, as I studied along with the contents of the book, I was able to answer almost all of the 1-minute quizzes correctly, and I felt a sense of accomplishment when the results came out accurately.
_Kim Ye-won

Each chapter introduces a project to be created, explains the concepts needed for the functions required for the project, takes a simple 1-minute quiz to check what you've learned, and finally, at the end, a project step where you can create the project introduced at the beginning, making it easy and fun to study the C language.
I studied every day without even realizing how much time had passed.
_Kim Young-heon

I once lost interest in learning the C language at school and gave up.
I became interested again, and by chance I came across this book.
It started to become fun as the principles and applications that I didn't know at the time were explained in an easy and clear way, and the knowledge gradually became organized in my head.
If you follow this book slowly, you will find yourself easily writing multiple lines of code and will naturally become interested in programming.
_Go Min-ji

The strength of this book is that it explains everything in great detail, starting from the basics.
Even if you are new to the C language, you can take on the challenge without any burden, and the difficulty level increases as you progress from the basics to the project part, so you can study up to advanced learning all at once.
