时钟类的完整程序

#include <iostream>
using namespace std;
class clock
{
public:
    void settime(int newh = 0, int newm = 0, int news = 0);
    void showtime();
private:
    int hour, minute, second;
};
void clock::settime(int newh, int newm, int news)
{
    hour = newh;
    minute = newm;
    second = news;
}

void clock::showtime()
{
    cout << hour << " " << minute << " " << second;
}
int main()
{
    clock c1;
    clock c2;//定义两个时钟对象c1和c2
    c1.settime();//未定义时间，则输出默认值
    c1.showtime();
    cout << endl;
    c2.settime(8, 30, 30);
    c2.showtime();
}
