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

#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？

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

unsigned short int hanshu(unsigned short int x, unsigned short int y) {
if (y == 0) return -1;
else return short int(x / y);
}

if(0==y)
return -1;

#include
using namespace std;
short int hanshu( unsigned short int x,unsigned short int y) {
if(0==y)
return -1;
else
return int(x/y);
};
int main() {
unsigned short int x,y;
cout<<"enter two numbers"< cin>>x>>y;
cout<<"the result is"<<hanshu(x,y)<<endl;
return 0;
}
