The armstrong number is of the form 153= 13 + 53 + 33
The input is : 153 or any other number
output: The number is armstrong or not.
Processing: take 153 as an example, remove 3, 5 and 1 in the reverse order (using % operator) and take the power of 3 and add to the sum variable.
if the total sum and the original number, both are same, then that is the arm strong number.
if else, the number is not an armstrong number
int original_num, check, temp, sum=0;
printf("Enter the number to check for armstrong number");
scanf("%d", &original_num); // Get the original number
while(original_num>0) //run the loop till the number becomes 0
check=original_num%10; //remove the last digit using modulo operator
sum=sum+check*check*check; //the last digit is taken power to 3 and added to sum
original_num=original_num/10; //truncate the last digit and run the loop again
printf("This is an armstrong numbern");
printf("This is not an armstrong number n");
