1) You forgot to import ``core.stdc.stdio``
2) String literal is of type string (which is an alias to
``immutable(char)[]``).
3) A slice is a pointer + length, and C doesn't understand
slices, so you must explicitly pass in the pointer from the
slice (the compiler would do this for you if you had the
literal in the arguments list instead of the variable).
```d
import core.stdc.stdio;
```
This generates ``` Error: undefined identifier `size_t` ```.
