源程序:
#include <iostream>
using namespace std;
class point
{
private:
	float x;
public:
	void f(float a)
	{
		x = a;
	}
	void f()
	{
		x = 0;
	}
	friend float max(point &a,point &b);
};
float max(point &a, point &b)
{
	return (a.x > b.x) ? a.x : b.x;
}
int main()
{
	point a, b;
	a.f(2.2);
	b.f(3.3);
	cout << max(a, b) << endl;
	system("pause");
	return 1;
}
运行结果:
