C++ Program to Print Armstrong Number Between 1 to n using While Loop
Write C++ Program to Print Armstrong Number Between 1 to n using While Loop
// CPP Program to Print Armstrong Number Between 1 to n using While Loop #include <iostream> #include <stdbool.h> #include <math.h> using namespace std; bool isArmstrong(int n) { int temp = n,ans = 0, rem; int digits = ceil(log10(n)); while(n != 0) { int remainder = n % 10; ans = ans + (remainder * remainder * remainder); n = n / 10; } if(temp == ans) { return true; } return false; } int main() { int n; cout << "Enter the number :--> "; cin >> n; int i = 1 ; cout << "Armstrong numbers between 1 to " << n << " :--> "; while(i < n) { if(isArmstrong(i)) { cout << i << " "; } i++; } return 0; }
Output:
Enter the number :--> 1000
Armstrong numbers between 1 to 1000 :--> 1 153 370 371 407
