好复杂…有没有人要尝试一下啊～

#include<stdio.h>
#include<math.h>
int main()
{
    int a,b,c,d;
    int count = 1;
    printf("请输入一个不多于5位的正整数：");
    scanf("%d",&a);
    c = a;
    printf("逆序：\n");
    while(c / 10 != 0)
    {
        count++;
 
        b = c % 10;
        printf("%d\n",b);
        c = c / 10;    
    }    
    b = c % 10;
    printf("%d\n",b);
    printf("位数是：%d\n",count);
    printf("顺序：\n");
    while(a % 10 != 0)
    {
        d = a / (int)pow(10,(count-1));
        printf("%d\n",d);
        a = a % (int)pow(10,count-1);
        count--;
    }
    return 0;
}
