Quiz question: Who can write ALIGNOF for c++ :-)

christos

#include <stdio.h>

#define ALIGNOF(type)	&(((struct { char c; type t; } *) 0)->t

void
main()
{
	printf("%d\n", ALIGNOF(char));
	printf("%d\n", ALIGNOF(short));
	printf("%d\n", ALIGNOF(int));
	printf("%d\n", ALIGNOF(long));
	printf("%d\n", ALIGNOF(long long));
	printf("%d\n", ALIGNOF(float));
	printf("%d\n", ALIGNOF(double));
}
