C :

#include<stdio.h>
int main(){
    int i,j,k;
    int N;
    for(i=1;i<10;i++){
        for(j=0;j<10;j++){
            for(k=0;k<10;k++){
            N=i*100+j*10+k;
            if(N==(i*i*i+j*j*j+k*k*k)){
                printf("%d\n",N);
            }
            }
        }
    }
return 0;
}

C++ :

#include <iostream>

using namespace std;
int main()
{
	int sum;
	int a, b, c;
	for (int i = 100; i<=999; i++)
	{
		sum = 0;

		a = i /100;
		c = i %10;
		b = (i/10) %10;
		sum = a*a*a + b*b*b + c*c*c;
		if (sum == i)
			cout<<i<<endl;

	}

	return 0;
}

Pascal :

var a,b,c,d:integer;begin

for a:=100 to 999 do

begin b:=a mod 10; c:=a mod 100 div 10; d:=a div 100;

if b*b*b+c*c*c+d*d*d=a then

writeln(a);

end;

end.

Java :

public class Main{
  public static void main(String[] args){
  	int x,y,z,N;
    for(N = 100;N < 1000;N++){
    	x = N / 100;
        y = (N / 10) % 10;
        z = N % 10;
      if(N == x*x*x+y*y*y+z*z*z)
        System.out.println(N);
    }
  }
}
