Program to dispaly armstrong number between 1 to 500

#include<iostream.h>
int main()
{
int sum,n,temp,rem;
cout<<"The Armstrong number between the range 1 to 500 are : \n"; 
for(int x=1;x<=500;x++)
{
n=x;
sum=0;
temp=n;
do
{
rem=n%10;
n=n/10;
sum=sum+rem*rem*rem;
}while(n!=0);
if(sum==temp)
cout<<x<<"\t";
}
cout<<"\t";
return 0;
}

Output:

 The Armstrong number between the range 1 to 500 are :
1        153         370       371        407

C++ Program to check whether number is Armstrong number

#include<iostream.h>
int main()
{
      int sum,temp,rem,n;
     cout<<"Enter the number \n";
     cin>>n;
     cout<<" Entered number is \t";
     cout<<n;
     cout<<"\n";
     sum=0; 
     temp=n;
      do
        {
                rem=n%10;
                n=n/10;
                sum=sum+rem*rem*rem;
           }while(n!=0);
     if(sum==temp)
            cout<<"This is Armstrong number.\n";
   else
           cout<<"This is not Armstrong number.\n";
return 0;
}

Output:-
