D ships with libc so everything in there is available

```C
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<ctype.h>
#include<math.h>
```


In d the equivalent imports:

```D
import core.stdc.stdio;
import core.stdc.string;
import core.stdc.stdlib;
import core.stdc.ctype;
import core.stdc.math;
```
