User declares required variables for this operation. User uses a temp variable that will use to store the value for temporary time period. Declaring while condition while (num>0) user ask to cub=num%10, num=num/10, sum=sum+ (cub*cub*cub).

Then a if-else condition if(temp==sum) then the number is Armstrong else it will not. And after creating all instance in the end display result on the screen as output.
