This website offers a comprehensive guide to learning Modern C++. The guide is intended for self-study and covers all the fundamental concepts of the language. The chapters are designed to be studied in a linear fashion, as later chapters build upon material presented earlier. The website also includes regular posts that cover topics not covered in the course. The course materials are freely available and can be downloaded or accessed on GitHub. The website also provides coding assignments for each chapter. Surprisingly, the last update was in 2023, indicating that the content is up-to-date.
