Mr. Armstrong
C programming code to check whether a number is an Armstrong
number or not. An Armstrong number is a number which is equal to
the sum of digits raise to the power of the total number of digits
in the number. Some Armstrong numbers are: 0, 1, 2, 3, 153, 370,
407, 1634, 8208, etc.
The algorithm to do this is: First we calculate the number of
digits in our program and then compute the sum of individual digits
raise to the power number of digits. If this sum equals the input
number, then the number is an Armstrong number otherwise not.
Examples:
7 = 7^1
371 = 3^3 + 7^3 + 1^3 (27 + 343 +1)
8208 = 8^4 + 2^4 +0^4 + 8^4 (4096 + 16 + 0 + 4096).
Sample Input:
371
Sample Output:
Total number of digits= 3
3^3= 27
7^3= 343
1^3= 1
Sum= 371
ARMSTRONG NUMBER!
