为什么这个程序只能进行一半，请会的指教。
#include<stdio.h>#include<math.h>
int main()
{
int num,indiv,ten,hundred,thousand,tenthousand,place;
printf("请输入一个整数（0-99999）：");
scanf("%d",&num);
if(num>9999) place=5;
else if(num>999) place=4;
else if(num>99) place=3;
else if(num>9) place=2;
else place=1;
printf("位数是%d\n",place);
printf("每位数位的数字是:");
tenthousand=num/10000;
thousand=(int)(num-tenthousand*10000)/1000;
hundred=(int)(num-tenthousand*10000-thousand*1000)/100;

switch(place)
