C++ Templates: Overload Resolution Using Concepts

Writing robust generic code in C++ requires managing complex template overloads, which can often lead to ambiguity or unexpected behavior. Modern C++ provides powerful tools, Concepts and Constraints, to simplify this process and improve code clarity. By the end of this course, you will understand the template ordering rules and be proficient in applying C++ Concepts to define precise requirements for your template parameters, ensuring the compiler always selects the intended function specialization. What you'll learn: * Understand the existing rules for template overload resolution and partial ordering in C++. * Learn the syntax and application of C++ Concepts to define semantic requirements for template arguments. * Apply constraints using the `requires` clause and constrained auto to improve template function signatures. * Practice ordering multiple template overloads explicitly using constraints to prevent ambiguity and errors. * Configure standard library concepts and simple type traits to validate and restrict template parameters effectively. We begin with the foundational principles of generic programming and template resolution before moving into practical examples of defining and applying custom constraints. The course focuses on reading and analyzing template code to ensure correct ordering and specialization. This course is designed for beginners familiar with basic C++ syntax who want to write modern, robust, and safe generic code. No prior experience with C++ Concepts is required.
