## Introduction

I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.

#include <iostream> #include <math.h> using namespace std; int main() { int lower, higher, i, temp1, temp2, remainder, n = 0, result = 0; //Reading two numbers from user cout<<"Enter two numbers: "; cin>>lower; cin>>higher; cout<<"Armstrong numbers between "<< lower << " and "<<higher << " are: "; for(i = lower + 1; i < higher; ++i) { temp2 = i; temp1 = i; // number of digits calculation while (temp1 != 0) { temp1 /= 10; ++n; } // result contains sum of nth power of its digits while (temp2 != 0) { remainder = temp2 % 10; result += pow(remainder, n); temp2 /= 10; } // checking if number i is equal to the sum of nth power of its digits if (result == i) { cout<<i<<endl; } // resetting the values to check Armstrong number for next iteration n = 0; result = 0; } return 0; }
