Question

用C++编写：求这样一个三位数,该三位数等于其每位数字的阶乘之和

Answer 1

int main()

{

int factor[7] = {1,1,2,6,24,120,720}; //7的阶乘已大于3位

int n = 100;

int result = 0;

for(; n < 1000; n++)

{

result = factor[n % 10] + factor[n / 10] + factor[n / 100];

if (n == result)

{

printf("rnnum:%d",n);

}

}

return 0;

}

大概这样,需要自己调试
