C++ Programming

Learn the basic C++ syntax for smooth learning of the series. We will cover essential content from assembly language to basic C++ syntax, STL, and C++11 in a compressed manner.

The best coding test lecture that helped students pass Naver, Kakao, and Samsung coding tests in just 10 weeks!

This is a 'C++' course for beginners in programming.

This is a game development & algorithm course that focuses on the algorithms and principles of 2D game development from the ground up using Windows API and C++.

You should stop programming by searching for and copying source code from Google. It is important to code freely on your own without relying on other people's code.

If you have studied basic grammar, you naturally want to try making something, right? This is a lecture designed to help beginner C++ programmers become proficient in object-oriented programming by creating simple games. We provide the 'minimum' code needed to start game programming on your own and share object-oriented know-how that cannot be mastered through grammar study alone. Have fun creating and quickly leap to an intermediate level or beyond!

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 is a practical Qt QML and C++ course strengthened by 6 essential, hands-on projects. Build your professional foundation through exercises covering everything from various types of UI development to REST API communication!

You can get started with desktop app development using Qt QML and C++. This course focuses on development targeting the Windows operating system. Development is also possible on macOS using the same methods.

Anyone who is a C/C++ developer can get started. You can quickly learn MFC Windows programming by selecting only the core. We also provide a 1200-page textbook.

C++ programming methods required in the field! It's time to move beyond C-style coding and start coding like a true C++ developer. This course is designed to help you build fundamental programming skills by learning the basic syntax of C++ step-by-step, growing to a level where you can apply them immediately in real-world practice. You can create practical projects using Arduino or develop the programming skills necessary for game development using Unreal Engine. Through this course, you will naturally boost your programming confidence and become comfortable utilizing C++ in practical applications.

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.

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!

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

If you use JS but find it difficult to explain why it works, this course provides the answer. From execution context, closures, and the event loop to Promise concurrency, prototypes, Virtual DOM, memory leaks, and bundle optimization—you won't just read about 18 chapters of advanced JS concepts; you'll learn by seeing them happen right before your eyes with a simulator. Code-based quizzes are provided for every chapter, and you can own it for life for the price of a single chicken dinner.

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.

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