What is Armstrong number?

Sum of a number’s digits raised to the power total number of digits is armstrong number.

Armstrong numbers example: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 153, 370, 371, 407, 1634 etc


3 = 3^1 = 3

153 = 1^3 + 5^3 + 3^3 = 153

Non-Armstrong numbers:

156 = 1^3 + 5^3 + 6^3 . This value is equal to 342. So, 156 is not an armstrong number.

Let see the below C Program:




void main()


int number, a, b, c, sum=0, count=0;

printf(“\n Enter the number”);















printf(“\n sum=%d”,sum);


printf(“\n The number is Armstrong”);


printf(“\n The number is not Armstrong”);
