以下是程序代码：


#include<stdio.h>
#include<math.h>
#define COUNT 6542

unsigned int zs[COUNT];                          //用于存放素数

void qzsf();
void fj();

void qzsf ()                                     //求素数，并存放在zs
{
    static unsigned int zs[COUNT];
    int z = -1;
    int i,j;
    double k;
    for(i = 2;i < 65535;i++)
    {
        k = sqrt (i);
        for(j = 2;j <= k;j++)
            if(i%j == 0)
                break;
        if(j>k)
            zs[++z] = i;
    }
}

void fj (unsigned num)                              //用递归输出结果
{
    int i;
    static unsigned int zs[COUNT];
    for(i = 0;zs[i] <= num;i++)
        if(num%zs[i] == 0)
        {
            printf ("%d*",zs[i]);
            fj (num%zs[i]);
        }
        else
        {
            printf ("%d\n",num);
        }
}

main()                                             //调用fj函数，对输入的数分解
{
    unsigned int num;
    printf ("The number:");
    scanf ("%ld",&num);
    fj (num);
}
