char* pointers between C and D

[ryuukk_]

Here is the way to do it with `writefln` (i think)


```D
import std;
import core.stdc.string;

void main()
{
     const(char)[] ch = "Hello World!";
     const(char)[] ch2 = "abc";
     const(char)* p;

     p = &ch[0];
     p++;
	
     auto str = p[0 .. strlen(p)];
     writefln("%s", str);
}
```

Note that i removed your `.dup` it is unecessary, string literals 
needs `const(char)`

After looking at the doc, `writefln` needs a slice, so we just do 
that and pass it
