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。。。点个赞再走吧！
