用java写高精度比较靠谱。
[java]
package lixiangmao;

import java.math.BigInteger;
import java.util.Scanner;

public class HDU1042{
    public static void main(String[] argc)
    {
        Scanner cin = new Scanner(System.in);
        BigInteger a,n,i;
        while(true)
        {
            a = cin.nextBigInteger();
            n = BigInteger.ONE;
            for(i=BigInteger.ONE; i.compareTo(a) <= 0; i = i.add(BigInteger.ONE))
                n = n.multiply(i);
            System.out.println(n);
        }
    }
}
