p49 求m与n之间的水仙花数

#include<stdio.h>
int main()
{
	int m, n;
	int a, b,sum,i,tmp;
	scanf("%d%d",&m,&n);
	for ( i=m; i <= n; i++)
	{
		tmp = i;
		sum = 0;
		do
		{
			a = tmp / 10;
			b = tmp % 10;
			tmp = tmp / 10;
			sum = sum + b*b*b;
		} while (a!=0);
		if (sum == i)
		{
			printf("%d\n",i);
		}
	}
	return 0;
