Answer 1

#include "stdio.h"
void main()
{
int a;
int num = 0;
scanf("%d",&a);
while (a!=0)
{
printf("%d\n",a%10);
num++;
a/=10;
}
printf("共有%d位数字\n",num);
return;
}

Answer 2

根据题目要求，我给你写了一个完整的程序给你参考。
源代码如下（vc++ 6.0下编译通过）：
#include <stdio.h>

#define MAX_NUM 4

int main(void)
{
int i = 0;
int num = 0;
int num_count = 0;
int a[MAX_NUM] = { 0 };

printf("please input a number(0-9999): \n");
scanf("%d", &num);

while (num % 10)
{
a[num_count++] = num % 10;
num /= 10;
}

printf("num_count: %d\n", num_count);

printf("sequence: \n");
for (i = num_count - 1; i >= 0; i--)
{
printf("%d ", a[i]);
}
printf("\n");

printf("inverted sequence: \n");
for (i = 0; i < num_count; i++)
{
printf("%d ", a[i]);
}
printf("\n");

return 0;
}

希望对你有帮助。
