Compile Time Programming
Compile time programming is a programming paradigm where code execution, computation, or metaprogramming occurs during the compilation phase rather than at runtime. It involves techniques like template metaprogramming, constexpr functions, and macros to perform tasks such as code generation, optimization, and validation before the program runs. This approach can improve performance, reduce runtime errors, and enable advanced code transformations.
Developers should learn compile time programming to write more efficient and safer code, especially in performance-critical applications like game engines, embedded systems, or high-frequency trading. It is essential for implementing compile-time optimizations, generating boilerplate code, and enforcing invariants early in the development process, which helps catch errors before deployment.
