编程学习网为您整理以下代码实例，主要实现：C++一元运算符重载，希望可以帮到各位朋友。
#include <iostream>
using namespace std;
class distance {
private:
int feet; // 0 to infinite
int inches; // 0 to 12
public:
// required constructors
distance() {
feet = 0;
inches = 0;
}
distance(int f, int i) {
feet = f;
inches = i;
}
// method to display distance
voID displaydistance() {
cout << "F: " << feet << " I:" << inches <<endl;
}
// overloaded minus (-) operator
distance operator- () {
feet = -feet;
inches = -inches;
return distance(feet, inches);
}
};
int main() {
distance D1(11, 10), D2(-5, 11);
-D1; // apply negation
D1.displaydistance(); // display D1
-D2; // apply negation
D2.displaydistance(); // display D2
return 0;
}
