Finding Armstrong Number with Function in C.

#include<stdio.h>

#include<math.h>

int armstrong(int n) ///receive the number

{

    double k,fact=1;

    double array[100];

    double pow_sum=0;

    int i=-1,j;

    double number=n;

    ///saving the number by 1 digit

    while(n!=0)

    {

        i++;

        array[i]=n%10;

        n=n/10;

    }

   ///calculate per digit power and add them

    for(j=0;j<=i;j++)

    {

      pow_sum = pow_sum + pow(array[j],i+1);

    }

    /// Compare total factorial value with the main number

    if(pow_sum==number)

    {

        printf("
This is an Armstrong Number
");

    }

    else

    {

        printf("
This is not an Armstrong Number
");

    }

}

int main()

{

    int n;

    printf("Please Enter A Number: ");

    scanf("%d",&n);

    armstrong(n); ///function call

    return 0;
