void find_peterson_num ( int num )
{
int sum;
int fact, i;
int temp = num;

do
{
for ( i = 1, fact = 1; i <= (temp % 10); i++)
{
fact *= i;
}

sum += fact;
temp /= 10;

} while ( temp > 0);

if ( sum == temp )
{
printf ( "%d is Perterson number of %d\n", num, sum );
}

printf ( "%d is NOT Perterson number of %d\n", num, sum );
}
