C语言:写一个判断水仙花数的函数，在主函数中输入一个3位的整数，输出其是否是水仙花数的信息。

#include
int isflower(int x) //是 返回1，不是返回0.
{
if(x<100 || x>999) //不是三位数
{
printf("Input error");
return 0;
}
int a,b,c;
a = x%10; // 个位上的数
b =x/10%10; //十位上的数
c = x/100; //百位上的数
if(a*a*a + b*b*b + c*c*c == x)
{
return 1;
}
return 0;

int main()
{
int n;
scanf("%d",&n);
if(isflower(n))
{
printf("yes");
}
else
{
printf("no");
}
return 0;
}
