如果第二个参数为0，则返回值为-1.那个-1怎么写出来啊，不会怎么输出-1

Question

#include
using namespace std;
unsigned short int hanshu(unsigned short int x,unsigned short int y) {
if (y==0)
cout<<"-1"< else
return short int (x/y);
}
int main() {
unsigned short int x,y;
cout cin>>x>>y:
cout<<"the result is"<<hanshu(x,y)<<endl;
return 0;
}
要怎么改啊？

Answer 1

unsigned short int 改成 signed short int
因为unsigned short int 取值为0-65535，
signed short int取值为-32,768 到 32,767
