# Generics/Metaprogramming in C

Exploring different ideas for implementing generics in C.

[01_no_metaprogramming](./01_no_metaprogramming) is the result of the code if implemented manually.

[02_macros](./02_macros) is an implementation that uses simple macros to define 2D and 3D vectors for different data types.

[03_xmacros](./03_xmacros) is an implementation that relies on X macros to allow for defining any N-dimensional vector for different data types. In this case, only 2D and 3D vectors were defined, but it can be easily expanded to other dimensions.

## General assessment of the different techniques
