c语言（8.1）
今天学习了水仙花数和组成多位数
#include<stdio.h>
int main()
{int n;scanf_s("%d", &n);int first = 1;for (int f = 1; f < n; f++){first *= 10;}for (int i = first; i < first * 10; i++){int temp = i;int sum = 0;while (temp != 0){int d = temp % 10;//d=3temp /= 10;//i=12//不要直接写成temp/10/*for (int j = 1; j < n; j++){d = d * d;//第一次循环完后，d为9//第二次就是d=9*9了，所以不能这么写}*/int power = 1;for (int j = 0; j < n; j++){//int power = 1;这个得放外面power = power * d; }sum = sum + power;}if(sum==i){printf("%d\n", i);}}return 0;
}#include<stdio.h>
int main()
{int n;scanf_s("%d", &n);for (int i = n; i <= 6; i++){for (int j = n ; j <= 6; j++){for (int k = n; k <= 6; k++){if (i != j && i != k && j != k){printf("%d%d%d ", i, j, k);}}}printf("\n");}return 0;
