编程学习网为您整理以下代码实例，主要实现：C++函数调用运算符()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;
}
// overload function call
distance operator()(int a, int b, int c) {
distance D;
// just put random calculation
D.feet = a + c + 10;
D.inches = b + c + 100 ;
return D;
}
// method to display distance
voID displaydistance() {
cout << "F: " << feet << " I:" << inches << endl;
}
};
int main() {
distance D1(11, 10), D2;
cout << "First distance : ";
D1.displaydistance();
D2 = D1(10, 10, 10); // invoke operator()
cout << "Second distance :";
D2.displaydistance();
return 0;
}
