C++ Architecture: Build a Modular Physics Engine

As C++ projects grow, managing code across multiple files becomes a major challenge. Understanding how to structure headers, prevent duplicate definitions, and organize code logically is essential for any aspiring software developer. This written course guides you through building a structured, multi-file physics engine from the ground up, helping you transition from writing single-file programs to designing clean, modular software. What you'll learn: - Understand how compiler translation units work and how to split code into header and source files. - Apply include guards and modern directives to prevent duplicate definition errors during compilation. - Organize code logically using namespaces to avoid naming collisions in complex projects. - Implement core physics engine math, including vectors and basic force calculations, across separate compilation units. - Manage dependencies between different components of a simulation engine without circular reference issues. - Practice building and compiling multi-file C++ projects using modern compiler flags. You will start with foundational concepts of compilation, linking, and header management before incrementally writing the components of your physics simulation. Each section introduces a key architectural pattern, followed by written code walkthroughs and conceptual exercises. This course is designed for beginner C++ programmers who want to move beyond basic syntax and learn how professional software is structured, with no prior experience in multi-file projects required.
