C语言取出一个数的每一位

int main()
{
	long t = 123456789;
	int a, b, c, d, e, f, g, h, i;

	a = t % 10;
	b = t / 10  % 10;
	c = t / 100 % 10;
	d = t / 1000 % 10;
	e = t / 10000 % 10;
	f = t / 100000 % 10;
	g = t / 1000000 % 10;
	h = t / 10000000 % 10;
	i = t / 100000000 % 10;

	printf("个位是：%d\n", a);
	printf("十位是：%d\n", b);
	printf("百位是：%d\n", c);
	printf("千位是：%d\n", d);
	printf("万位是：%d\n", e);
	printf("十万位是：%d\n", f);
	printf("百万位是：%d\n", g);
	printf("千万位是：%d\n", h);
	printf("亿位是：%d\n", i);
	getchar();
	return 0;
