Check if a number is Armstrong

सबसे पहले ऊपर दिए गए numbers को check कर लेते हैं कि ये number Armstrong हैं या नहीं। तो जैसा कि अभी आपने ऊपर पढ़ा कि अगर number , इसमें present हर digit के cubes के total के बराबर होना चाहिए।

11 = 1
21 = 2

इसी तरह से 153 , हालाँकि इसमें 3 digit हैं इसीलिए हर digit पर 3 की घात होगी।

13 = 1
55 = 125
33 = 27
Total : 1 + 125 + 27 = 153

इस article में C language में हम Armstrong number check करने के लिए एक program बनाएंगे।

C program to check if a number is Armstrong

#include <stdio.h> #include <math.h> int main() { int num, originalNum, remainder, n = 0, result = 0; printf("Enter an integer: "); scanf("%d", &num); originalNum = num; // store the number of digits of num in n for (; originalNum != 0; ++n) { originalNum /= 10; } // reset originalNum to num originalNum = num; while (originalNum != 0) { remainder = originalNum % 10; result += pow(remainder, n); originalNum /= 10; } if (result == num) printf("%d is an Armstrong number.", num); else printf("%d is not an Armstrong number.", num); }
