C++ Concepts: Template Constraints Explained

In C++, the role of concepts is to define a generic constraint to restrict the type range of template parameters. By using concepts, type checking of template parameters can be performed at compile time to ensure that template functions or classes can accept types that meet specific requirements when instantiated. This helps to prevent type errors at compile time, improving the reliability and maintainability of the code. Concepts also make the code more readable and understandable as they allow for clear specification of the requirements for template parameters.
