要么太难看不懂，要么太简单降低智商？ 那么这个题解就很适合你
#include <iostream> using namespace std; int main() { int m, n, cnt = 0; cin >> m >> n; for(int i = m; i <= n; i++) { if(i < 100 || i > 999) continue; int a = i / 100; int b = i / 10 % 10; int c = i % 10; if(a*a*a + b*b*b + c*c*c == i) { cout << i << " "; cnt++; } } if(cnt == 0) { cout << "No Answer."; } else { cout << endl << cnt; } return 0; } -

水题。 AC代码：
#include<iostream> #include<math.h> using namespace std; int m,n; bool check(int x){//自定义函数 int s=0,y=x; while(y!=0){ s+=pow(y%10,3);//求每个数位上的数的立方 y/=10;//删除当前数位 } if(s==x)return true;//是水仙花数 else return false;//不是水仙花数 } int main(){ int sum; cin>>m>>n; for(int i=m;i<=n;i++){ if(check(i)){//引用自定义函数 cout<<i<<" "; sum++; } } if(sum>0)cout<<endl<<sum;//有水仙花数 else cout<<"No Answer.";//没有水仙花数 return 0; }无注释纯净版：
#include<iostream> #include<math.h> using namespace std; int m,n; bool check(int x){ int s=0,y=x; while(y!=0){ s+=pow(y%10,3); y/=10; } if(s==x)return true; else return false; } int main(){ int sum; cin>>m>>n; for(int i=m;i<=n;i++){ if(check(i)){ cout<<i<<" "; sum++; } } if(sum>0)cout<<endl<<sum; else cout<<"No Answer."; return 0; }可能或许大概稍微写得难了一点点。。。
