What is metaprogramming in C++?

Lecture 6 - Slide 28 : 40

Metaprogramming in C++ emphasizes compile time computations that yields types or functions

C++ offers compile time functional programming

constexpr in C++11
- Possible compile time calculations
Type functions
- Calculation of types at compile time
- Type returning functions
Support of selection - in between types
- "Compile Time if-else"
Support of iteration
- Via recursion
Other names for metaprogramming
- Two-level programming, generative programming, template metaprogramming

A metaprogram is a compile time computation yielding types or functions to be used at run time (§28.1, 4ed)
