generating armstrong number to nth number in c not working

I am trying to generate armstrong number to nth number.So,I have written a code for that,but it is not working.Everytime I input a number like 999 or 10000,it return only 0....can anyone please help me to find out what's wrong with this code: 

#include <stdio.h>
#include <math.h>
int main()
{
    double remainder,n=0;
    int number,sum = 0,q,x,count;

    printf("Enter an integer upto which you want to find armstrong numbers:");
    scanf("%d",&number);
    printf("\nFollowing armstrong numbers are found from 1 to %d\n",number);

    for( count = 1 ; count <= number ; count++ )
    {
        q = count;
        x = count;
        for(;x != 0;)
         {
          x =x / 10;
          n = n + 1;
         }
        while(q != 0)
        {
           remainder = q % 10;
           sum = sum +(pow(remainder,n));
           q = q / 10;
        }
        if ( count == sum ){
        printf("%d\n", count);
        }
        sum = 0;
        }

   return 0;
}

You have to initialize n to zero inside the loop for count. And take care of proper rounding of the result of pow by for example adding 0.5 to it.
