Seven Tips to Get Rid of the Junior Programmer Tag!

Learn C programming fundamentals with 120 examples and 270 illustrations!


Knowing "why" you're using it can help you use it "well"! Understanding the C language from background knowledge is as easy as flowing water!
There are surprisingly many people who learn all the C language grammar but cannot write a single line of code.
Because I only learned how to use grammar without understanding the principles.
This book continuously asks the question, "Why?" and explains the background knowledge of the C language grammar step by step.
Building a foundation of C language concepts in your head based on background knowledge will prevent you from stuttering when you actually pick up the keyboard and start coding.
Additionally, the 270 diagrams and illustrations, created through extensive research by the author and editorial staff, help readers more easily understand why the grammatical elements of the C language were created.


Coding Interview! Start with grammar used in "real-world" situations to get your fingers and mouth moving!
Companies are increasingly using coding interviews when hiring new developers.
However, among the C language grammar, there are many grammars that only appear in grammar books and are not actually used in real-world situations.
If you study everything without understanding its importance, it will only be a waste of time.
This book quickly organizes parts that can be intuitively understood and explains in detail grammar that is frequently used in actual fields.
Additionally, the book includes the author's practical know-how and tips for junior programmers working in the field.
It will also be very useful in interviews.

You're not alone! If you have any questions about coding, ask the author and your peers to learn!
It's really hard for beginners to figure out why their self-made programs aren't working and what they're doing wrong.
But readers of this book are by no means alone.
In the author's online community (cafe.naver.com/tipscommunity), the author and seniors who studied the C language first answer readers' questions.
In particular, if you solve the 'utilization problems' included at the end of each chapter of the second yard and post your answers to the community, you can even receive feedback on your code.


Discover the Do It! series' unique learning design! Suitable for both self-study and textbook use!
Start learning C language on your own with a 31-day completion progress chart and video lectures!
C language is not difficult.
It just feels difficult because of the unfamiliar expressions.
The 31-day progress chart provided in this book helps you study systematically by pointing out difficult and important parts.
Additionally, the author's friendly video lectures, which have taught over 1,000 beginners, are available online for free for life.


120 practice examples + 1-minute review quizzes + practice problems, making it ideal as a textbook for academies or universities!
It can be difficult to understand the C language grammar explanation just by looking at it.
This book stands out for its learning design, which makes it easy to learn difficult C grammar and not forget it.
We provide thorough explanations from Visual Studio installation to development environment setup, allowing you to practice coding examples that help you understand grammar.

In this book, a one-minute quiz is always included right after each important concept or example.
Let's make sure to solve the problems so that we don't forget the concepts we just learned.
Finally, it also includes practice problems at the end of each chapter to review the concepts, making it suitable for use as a textbook in academies or universities.
