5) What's wrong with this program? Is it that `printf` doesn't

int main() {

You can use toStringz() from std.string to convert D strings to 
null terminated strings when you need to interface with C 
functions. But in this case, writeln() would be the simplest 
solution. It would be only:

writeln(foo());

Instead of:

printf("%s\n", toStringz(foo()));

I'm a newbie in D too, so correct me if there is anything wrong.
