对呀，这样改警告就没啦

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main(void)
{
    int count=0;
    char  key[][100]={"ling","yi","er","san","si","wu","liu","qi","ba","jiu"};
    char num[1000];int a[100];
    scanf("%s",num);
    int index=1;
    int gewei = 0;
    for(int i=0;num[i]!='\0';i++)
    {
        count=count+((int)num[i]-48);
        if(count/index>0)
        {
            gewei++;
            index *=10;
        }
    }
    
    for(int i=gewei;i!=0;--i)
   { a[i]=count%10;
      count= count/10;
      }
      for(int i=1;i<=gewei;++i)
      {  printf("%s ",key[a[i]]);
         
          }printf("%c",8);   
    return 0;
}
