#include <stdio.h>



int main()
{
    while(1)
    {
        
             short m = 1;

        scanf("%d",&m);
        
        if(m == 0) break;
    
        printf("m  is  %d\n",m);
        
      }
         getch();
    return 0;
}


当输入 0  时，会报错：Run-Time Check Failure #2 - Stack around the variable 'm' was corrupted.


这是为什么啊？
