How does C++ metaprogramming work?

C++ metaprogramming enables developers to write programs that generate code at compile time rather than runtime. This technique leverages C++ templates and its ability to perform operations on types at compile-time. C++ templates are essentially functions that operate on types rather than values, meaning that they can take types as arguments and return types as output. Metaprogramming leverages this capability to create templates which can modify and generate new code at compile time. As a result, C++ metaprograms can automatically generate code templates, simplify code reuse, reduce code size, and improve performance. Metaprogramming is a powerful tool, but can be difficult to learn and use effectively.
