Armstrong Numbers Between Two Integers

Armstrong Numbers Between Two Integers

In case of an Armstrong number of 3 digits, the sum of cubes of each digits is equal to the number itself.

For example: 407 = 4*4*4 + 0*0*0 + 7*7*7  // 407 is an Armstrong number.

#include <stdio.h>
#include <math.h>

int main()
{
    int low, high, j, temp1, temp2, remainder, n = 0, result = 0;

    printf("Enter two numbers(intervals): ");
    scanf("%d %d", &low, &high);
    printf("Armstrong numbers between %d an %d are: ", low, high);

    for(j = low + 1; j < high; ++j)
    {
        temp2 = j;
        temp1 = j;

        // 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;
        }

        // checks if number j is equal to the sum of nth power of its digits
        if (result == j) {
            printf("%d ", j);
        }

        // resetting the values to check Armstrong number for next iteration
        n = 0;
        result = 0;

    }
    return 0;
}

C++ Programming Finds Length of Strings - To find the length of the string in 'C++', ask to enter the string and then Find the Length the that string using function "strlen()" of string.h library and display the length value of a string
