我收到一个错误,说我无法访问私人成员x和y.如何编写方法getX()和getY()以便它们可以看到x和y?谢谢.
#include <iostream>
#include <string>
using namespace std;
class Point {
public:
Point(int x, int y);
Point();
int getX();
int getY();
private:
int x, y;
};
int Point::getX() {
return x;
}
int Point::getY() {
return y;
}
void main () {
Point p(5,5);
Point g;
cout << p.x << endl;
cout << g.y;
string s;
cin >> s;
}

嗯,你已经有书面getX和getY,你只需要使用它们:
cout << p.getX() << endl;
cout << g.getY();

请注意,因为getX()并且getY()不修改您的类,它们应该是const:
class Point {
public:
// ...
int getX() const;
int getY() const;
// ...
};
// ...
int Point::getX() const {
return x;
}
int Point::getY() const {
return y;
}
// ...
