我重载了booking类中的less then运算符。
#include <iostream>
using namespace std;
class Booking{
private:
long bookingID;
public:
Booking(long bookingID) : bookingID(bookingID){}
long getBookingID(){
return bookingID;
}
bool operator<(Booking &b){
return this->bookingID<b.getBookingID();
}
}
int main(){
Booking* b2 = new Booking(11);
Booking* b1 = new Booking(2);
cout << (b1<b2) << endl; // returns 0 (expected 1)
cout << (b2<b1) << endl; // returns 1 (expected 0)
return 0;
}
问题是什么？ 还是我误会了什么？
您正在比较指针，而不是对象。
你的意思是:
Booking b2( 11);
Booking b1( 2);
cout << (b1<b2) << endl; // returns 1, as expected
cout << (b2<b1) << endl; // returns 0, as expected
