Concepts (C++)

In C++, "concepts" are a way to specify requirements for template types, improving code clarity and safety. Think of concepts as criteria—like ensuring a tool fits specific screws. For example, if a function is meant to work with numbers, a concept can enforce that the input type is indeed a number. This helps catch errors at compile time rather than during program execution, leading to more robust and understandable code. Concepts enhance template programming by making code easier to read and maintain while providing better error messages when type mismatches occur.
