Hi Anuj Khare
every time value of variable 'm' is always 0

#include<iostream>
using namespace std ;

int main(){
int s,m;

for(int i=0;i<500;i++)
{
int sum=0;
cout<<m; //0
while(m>0) /*(0>0) giving false so not going inside while loop*/
{
s=i%10;
sum+=s*s*s;
m/=10;

}

if(sum==i){

/* for first iteration of for loop value of i is 0 so going inside if block and printing 0 as sum=0 */

cout<<"armstrong number :"<<i<<endl;

}

}

return 0;
}

To fix it
inside the for loop add m=i
and inside the while loop do
s=m%10 instead of s=i%10 as if we use latter it will change the value of i and is needed at the end to compare with variable 'sum'.
