c语言计算1997的阶乘

以下是C语言计算1997的阶乘的代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX 10000

int main()
{
    int a[MAX], i, j, n, temp, m = 1;
    memset(a, 0, sizeof(a));
    a[0] = 1;
    for (i = 1; i <= 1997; i++)
    {
        temp = 0;
        for (j = 0; j < m; j++)
        {
            n = a[j] * i + temp;
            a[j] = n % 10;
            temp = n / 10;
        }
        while (temp > 0)
        {
            a[m] = temp % 10;
            temp = temp / 10;
            m++;
        }
    }
    printf("1997! = ");
    for (i = m - 1; i >= 0; i--)
    {
        printf("%d", a[i]);
    }
    printf("\n");
    return 0;
}
