Template metaprogramming

Template metaprogramming is a programming technique primarily used in C++ that allows developers to write code that generates other code at compile time. Instead of specifying exact types, programmers can define templates that work with any type, enabling flexible and reusable code. This approach allows for optimizations and complex functionalities without sacrificing performance. Essentially, it lets programmers create algorithms and data structures that can adapt based on the types they are given, leading to more efficient and maintainable software.
