Why does it only give two answers for any inputs?

Question

#include<stdio.h>
#include<math.h>
int fact(int);
void main()
{
int n,k,x,sum,a,b,i;
printf("enter any numbers:");
scanf("%d%d",&a,&b);
for(i=a;i<=b;i++)
{
sum=0; k=i; n=i;
while(n>0)
{
x=n%10;
sum=sum+fact(x);
n=n/10;
}
if(sum==k)
printf(" %d",sum);
}
}
int fact(int y)
{
if(y==1)
return 1;
else
return (y*fact(y-1));
}
