class point
{
public:
friend class tamgiac;
private:

float fxhoanhdo;
public:
float laytungdo();
float layhoanhdo();
void dattungdo(float ftungdo);
void dathoanhdo(float fhoanhdo);
int nhapdiem();
int xuatdiem();
};
Code:
#include "point.h"
#include <iostream>
using namespace std;
float point::laytungdo()
{
return fytungdo;
}
float point::layhoanhdo()
{
return fxhoanhdo;
}
void point::dattungdo(float ftungdo)
{

}
int point::nhapdiem()
{
cout << "Nhap Tung Do:";
cin >> this->fytungdo;
cout << "Nhap Hoanh Do:";
cin >> this->fxhoanhdo;
return 1;
}
int point::xuatdiem()
{
cout << "(" << this->fytungdo << "," << this->fxhoanhdo << ")";
return 1;
}
Code:
