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.

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"

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

This is a project-oriented course where you will build a "ToDo List" app using React and TypeScript with a professional touch. Beyond simply learning syntax, you will gain practical experience in using TypeScript by completing a real-world service—from component structure design and state management to type application, feature implementation, local storage integration, and deployment.

This course is a video lecture that systematically covers the core modern JavaScript syntax essential for learning React.js and Vue.js frontend development. It is structured to help you develop efficient coding skills through ES6+ syntax, latest features, and practical examples that can be directly applied to work and learning.

The first class in the curriculum, "Anyone Can Learn Python", is an introductory programming course for those with no programming/coding experience. Based on my experience with numerous classes taught to non-majors, this class focuses on the "story" and "principles" from the structure of a computer to how programs work and the role of programming languages in this process, allowing beginners to approach the unfamiliar concept of programming more familiarly. In addition, by adopting the Python language, which has recently been growing at an incredible rate, the barrier to entry for programming has been lowered even further, and when explaining the grammatical elements of the language, the focus is on "Why" and "How" rather than "What", so that it is not a simple grammar memorization class, but rather on real-world examples and practical applications. Based on the incorrect learning methods that beginners often use, it also covers tips on how you should view and learn programming in the future, and based on the trial and error I experienced while struggling and wasting time while teaching programming on my own in the past and the inner strength I gained from conducting offline classes for many years, it focuses on what beginners find difficult and how to convey it, so it will be of great help to those who are hesitant about getting started with Python.

We will develop a web app that collects data using concurrent/parallel programming in Python, loads it into MongoDB, analyzes it, and visualizes the collected data using FastAPI, a modern web framework. In the process, you will learn and understand Python concurrent/parallel programming using coroutines, multi-threading, and multi-processing, and understand how to use them to improve Python's performance. We will help you apply Python concurrent/parallel codes directly to your work. We will not only teach you how to develop and end, but also how to deploy and operate an actual app on the AWS cloud.

🎯 Course Summary This is an introductory course designed to build a **solid foundation in C++** before diving into Unreal Engine. While this course does not involve direct hands-on practice with Unreal Engine, it covers the core concepts of C++—such as variables, memory, pointers, references, classes, object-oriented programming, inheritance, polymorphism, dynamic allocation, and smart pointers—step-by-step to ensure you have a firm grasp when you eventually learn Unreal C++. The focus is not just on memorizing syntax, but on understanding **why these rules exist, how the code actually operates, and where to look when problems arise.** The course proceeds in the following direction: 1. **Programming Fundamentals and Basic C++ Syntax** Solidify basic syntax including variables, data types, operators, conditional statements, loops, and functions. 2. **Understanding Memory and Objects** Learn about pointers, references, arrays, dynamic allocation, object creation and destruction, and copying and moving. 3. **Fundamentals of Object-Oriented Programming** Cover concepts of classes, encapsulation, constructors and destructors, inheritance, polymorphism, and virtual functions. 4. **Building Practical C++ Strength** Prepare the foundation for future Unreal C++ learning through basic STL containers, iterators, algorithms, and smart pointers. Through this process, learners will go beyond simply following C++ syntax and develop the fundamental ability to understand the principles of how code works and make independent judgments. --- ## 💡 One-Line Summary An introductory course to solidify the basics and operating principles of C++ before learning Unreal Engine, ensuring a natural transition to Unreal C++ studies. --- ## 📌 Pre-course Notice This is not a practical Unreal Engine course, but a **C++ introductory course** required before learning Unreal. Basic experience in creating and managing files and folders in a Windows environment will be helpful for your learning.
