C Template Metaprogramming | Concepts

To handle "base cases" (the exit condition for recursion).

In standard C++, a function takes values and returns a value. In TMP, a takes types or constants and "returns" a new type or constant. C Template Metaprogramming Concepts

Modern C++ (C++14/17/20) has shifted much of the "heavy lifting" from pure template syntax to constexpr and consteval functions. These allow you to write logic that looks like normal C++ but is guaranteed to run at compile time, significantly reducing the complexity of traditional template syntax. Why Use It? To handle "base cases" (the exit condition for recursion)

C++ (TMP) is essentially a "program within a program." It allows you to execute logic during compilation rather than at runtime, using the compiler as an interpreter to generate optimized code. 1. The Core Mechanism: Functional Programming Modern C++ (C++14/17/20) has shifted much of the

TMP is a purely sub-language. Because the compiler cannot "change" a value once it is defined during a build, you don't use loops or variables. Instead, you use: Recursion: To mimic loops.

The primary goal of TMP is . By moving logic to the compilation phase, the final executable is smaller and faster because the work has already been done by the compiler before the user ever runs the program.
