#include <iostream>
using namespace std;




class Armstrong{
	int startnumber;
	int endnumber;
public:


	Armstrong(int sn , int en){
		startnumber = sn;
		endnumber = en;       
	}
	void findArmstrongNumbers(){
		for(int number = startnumber; number <= endnumber; number++){
			int sum = 0;
			int temp = number;
			while(temp > 0)  {    
				int d = temp%10;    
				sum += d*d*d;    
				temp /= 10;    
			}
			if(number == sum) {
				cout<<number<<"\n";
			}   
				
		}
	}
};
int main(){
	
	int startnumber;
	int endnumber;


	cout<<"Input start number: ";
	cin>>startnumber;
	cout<<"Input end number: ";
	cin>>endnumber;
	Armstrong armstrongChecker(startnumber, endnumber);
	armstrongChecker.findArmstrongNumbers();


	system("pause");
	return 0;
