Question

如题所述

Answer 1

#include <iostream>
using namespace std;
class Coordinate
{
// 友元函数
friend void display(Coordinate &coor);
public:
Coordinate(int x, int y)
{
m_iX = x;
m_iY = y;
}
public:
int m_iX;
int m_iY;
};

void display(Coordinate &coor)
{
cout << "m_iX：" << coor.m_iX << endl;
cout << "m_iY：" << coor.m_iY << endl;
}

int main(void)
{
Coordinate coor(1,2);
display(coor);
return 0;
