编程学习网为您整理以下代码实例，主要实现：C++输入/输出运算符重载，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;
}
frIEnd ostream &operator<<( ostream &output, const distance &D ) {
output << "F : " << D.feet << " I : " << D.inches;
return output;
}
frIEnd istream &operator>>( istream &input, distance &D ) {
input >> D.feet >> D.inches;
return input;
}
};
int main() {
distance D1(11, 10), D2(5, 11), D3;
cout << "Enter the value of object : " << endl;
cin >> D3;
cout << "First distance : " << D1 << endl;
cout << "Second distance :" << D2 << endl;
cout << "Third distance :" << D3 << endl;
return 0;
}
