# C23META

## Experiments with c23's preprocessor

Implements numeric computation and collections using only the C Preprocessor.

```c

#include "numbers/numbers.h"

#include "collections/list/list.h"

#define FACTORIAL(N)\

  LIST_FOLDL(U128H_MUL,\

    LIST_MAP(U128H_FROM_U32H,\

      LIST_RANGE(U32H_1, N)), U128H_1)

#define S(X) STRING(U128H_PRINT(X))

int main(void) {

  printf("%s\n", S(FACTORIAL(U32H_1)));

  printf("%s\n", S(FACTORIAL(U32H_5)));

  printf("%s\n", S(FACTORIAL(U32H_10)));

  printf("%s\n", S(FACTORIAL(U32H_15)));

  printf("%s\n", S(FACTORIAL(U32H_20)));

  printf("%s\n", S(FACTORIAL(U32H_30)));

}

```

```
