#include<iostream>
using namespace std;

class Clock{
public:
Clock(int newH, int newM, int newS);
void setTime(int newH, int newM, int newS);
void showTime();
private:
int hour, minute, second;
};

Clock::Clock(int newH, int newM, int newS){
hour = newH;
minute = newM;
second = newS;
}

int main()
{
Clock c(0,0,0);
c.showTime();
c.setTime(8,30,30);
system("pause");

源代码是这个

Answer 1

你的这两个函数的实现呢
void setTime(int newH, int newM, int newS);
void showTime();
