编写函数，参数为两个 unsigned short int

#include <iostream.h> 
  
short int Divider(unsigned short int a, unsigned short int b) 
{ 
if (b == 0)  
return -1;  
else 
return a/b; 
} 
  
typedef unsigned short int USHORT;  
typedef unsigned long int ULONG;  
int main() 
{ 
USHORT one, two;
short int answer;
cout << "Enter two numbers.\n Number one:";  
cin >> one; 
cout << "Number two: ";  
cin >> two; 
answer = Divider(one, two);  
if (answer > -1) 
cout << "Answer: " << answer;  
else 
cout << "Error, can't divide by zero!"; 
return 0;
}
