After studying the operating principles of computers, C language syntax, and application methods through Hong Jeong-mo's 'C Programming: Learning by Doing,' this course will naturally bridge you to the subject of Data Structures from a programming perspective. It will serve as both C language practice and a way to instill the core concepts of data structures into your mind.

If C++ could be learned easily, would there be any reason not to learn it? This course provides kind and detailed explanations to help beginners who dream of a career as a successful programmer but currently feel anxious day by day. If you want to move beyond being a beginner and step onto the path toward becoming an intermediate or even advanced programmer, this will be your best stepping stone. I am rooting for your dreams!

Learn the core systems required for Unity game development. We reveal the secrets of AAA game developers. Quickly implement your own gameplay on top of a stable, pre-established design and system.

These mock technical interview questions were created by Jushin Game Academy, which has produced numerous game client developers over the past 10 years, based on their diverse experiences. We will support your employment as a game client developer.

You can systematically learn stock trading automation using Python and the Interactive Brokers API, which holds the top spot in global market share.

This course is for those who are preparing for an algorithm test using the C/C++ programming language. The purpose of this course is to develop problem-solving skills using algorithms and data structures.

Even if you know nothing about coding, you can create your own scheduling app in just 4 weeks. Simply tell the AI, "Make an app like this," and paste the code you receive into Swift Playgrounds. Over 12 sessions—3 times a week, 30 minutes a day—you will complete a real app featuring adding/deleting/editing schedules, categories and notifications, filters and search, and even a calendar view. Don't worry if you run into errors; just ask the AI, and it will fix them for you. Start the challenge now to learn how to collaborate with AI, rather than just studying coding!

I had previously created a simple engine structure with DX11, and now this is a course where the functionality implementations of the engine transitioning to DX12 are implemented in earnest. From the standpoint of having developed my own engine for a long time, I have made efforts to make it easy to approach so that many people can develop their own engines. Stop struggling with GPT, Google, and searching for materials anymore.

This course is for those who want to prepare for coding tests in the form of real mock exams. Each mock exam consists of 5 questions. It would be good to take my course, "Algorithm Problem Solving for IT Employment".

This course goes beyond simple grammar explanations and focuses on developing C++ programming skills that can be applied immediately in the field. Throughout my teaching, I have directly addressed common challenges faced by many learners—such as struggling to understand the STL or feeling confused by file handling and exception handling concepts. Based on this experience, I provide step-by-step explanations to ensure even complex concepts are understood easily and clearly. Furthermore, this course is not just about delivering theory; it is structured around: 👉 "Why this concept is necessary" 👉 "How it is used in actual code" 👉 "How it is applied in professional practice"

In this course, you will learn Kotlin syntax, how to safely convert Java projects to Kotlin, and how to code in a Kotlin-like manner. Learn Kotlin based on practical code and use it yourself to enjoy its advantages.

This is a practical Qt QML and C++ course built on 6 invaluable projects. Build your fundamental skills for real-world work through practice that covers various UI development and REST API communication!

You can learn the basics of React. You can organize HTML, JavaScript, DOM, Event, Object, Module, OOP, etc. related to React.

Java Programming Based on Object-Oriented Concepts for Computer Science Majors

Modern C++ Programming based on Object-Oriented Concepts for Computer Science Majors

When learning Swift, the iOS programming language, it can be confusing when multiple concepts appear all at once. That's why I created this course with the principle that "when understanding a new concept, only previously learned concepts should be used." So this course is meticulously designed with a sequential structure between concepts, where only one new concept appears at each stage, and no other unfamiliar concepts appear at all. One concept per minute, 180 concepts total. From the basics of variables and constants to understanding memory structure from a CS perspective, and even the latest syntax for asynchronous processing. In 3 hours, you'll learn 180 core concepts in the designed order.

This is an introductory Java course designed so that even those starting programming for the first time can follow along. You will systematically learn everything from JDK 21 environment configuration to variables, data types, control flow statements, arrays, strings, and the core concepts of Object-Oriented Programming (OOP) such as classes, inheritance, polymorphism, and exception handling. Rather than simply listing syntax, we explain "why it works this way" to help you build a solid foundation.

This course goes beyond simple kit assembly; it is a process of building the open-source project Otto DIY from scratch. We have included everything from the secrets of component selection and hardware operating principles to Arduino coding (functions, variables, loops), and even the troubleshooting know-how for voltage drops, which beginners find most challenging. Don't just stop at theory—develop the skills of a 'true robot maker' by completing your own smartphone-controlled robot!

Scala allows you to write much more concise and robust code quickly, while still leveraging the experience you have gained as a Java developer. This course is designed for Java developers to quickly understand the overall look of Scala based on their existing Java knowledge. If you are an existing Java developer, you can learn Scala very easily.

Through the 25 patterns of OODP, you will learn various ways to design software in an object-oriented manner.

Learn various design principles needed to write object-oriented code, focusing on working code.

Easily learn data structures and algorithms, which were difficult to learn with C++, in easy steps. Unlike typical lectures, this course combines data structures and algorithms, allowing you to learn them simultaneously while considering their interrelationships.
