Question

Armstrong numbers are numbers that are equal to the sum of their digits raised to power of the number of digits in them. The number 153, for example, 1^3 + 5^3 + 3^3. Thus it is an Armstrong number. Write a program to display all three digit Armstrong numbers.

Answer 1

C program to display all three digit Armstrong numbers:

# include < stdio.h > # include < math.h > main () { int n, t, onesdigit, tensdigit, hunsdigit: print f ('' The three digit Armstrong numbers are: \n ''): n = 100: while (n < = 999) { onesdigit = n - ((n/10) * 10): tensdigit = (n/10) - ((n/100) * 10): hunsdigit = (n/100) - ((n/1000) * 10): t = pow (onesdigit, 3) + pow (tensdigit, 3) + pow (hunsdigit, 3): if (t = n) { print f (''ln % d'', t): } n + + } }
