The ones who are crazy enough to think they can change the world are the ones who do.- Steve Jobs

When an n-digit number is equal to the sum of the n^{th} powers of its digit, then it is said to be an Armstrong Number.

- 1
^{1}= 1 , then**1**is an armstrong number. - 1
^{3}+ 5^{3}+ 3^{3}= 153, then**153**is an armstrong number. - 1
^{4}+ 6^{4}+ 3^{4}+ 4^{4}= 1634, then**1634**is an armstrong number. - 2
^{2}+ 5^{2}= 29, then**25**is not an armstrong number. - 1
^{3}+ 2^{3}+ 3^{3}= 36, then**123**is not an armstrong number. - 1
^{4}+ 1^{4}+ 1^{4}+ 1^{4}= 4, then**4**is an armstrong number.

Okay, Its time for challenging your mathematic friend to find whether the given number is an armstrong or not. As the race starts, you, the programmer will start writting a C program to find the given number is armstrong or not, but your mathematic friend will wins the race for first question by simply doing a mathematic calculations with paper and pen. But to find whether the given series of numbers is armstrong or not, Definitely you wins. Here is a C program to find whether a given number is armstrong or not to help you.

c-armstrong-number.c

#include <stdio.h> int main() { int a, b, c, z; printf("Enter a number : "); scanf("%d",&a); b = a; z = 0; while(a > 0) { c = a % 10; z = z + (c * c *c); a = a / 10; } if(z == b) printf("\n%d is an armstrong number", b); else printf("\n%d is not an armstrong number", b); return 0; }

Enter a number : 153 153 is an armstrong number
