求水仙花数

#include <iostream>using namespace std;
int main(){ int num = 100; do {    int a = 0;//个位 int b = 0; int c = 0;
 a = num % 10; b = num / 10 % 10; c = num / 100;
 if(a*a*a+b*b*b+c*c*c == num) { cout << num << endl; } num++; } while (num < 1000); system("pause");
 return 0;}

敲桌子

#include <iostream>using namespace std;
int main(){ int n = 100; for (int n = 1; n < 100; n++) { if (n % 7 == 0 || n % 10 == 7 || n / 10 == 7) { cout << "敲桌子"<< endl; } else  { cout << n << endl; } }
 system("pause");
 return 0;}
