c++中显示函数不接受3个参数怎么办

Question

Answer 1

我试了下，这个没问题呀：

#include <iostream>

using namespace std;

class Clock
{
private:
    int Hour, Minute, Second;

public:
    void setTime(int, int, int);
    void showTime();
};

void Clock::setTime(int H, int M, int S)
{
    Hour = H;
    Minute = M;
    Second = S;
}

void Clock::showTime()
{
    cout << Hour << ":" << Minute << ":" << Second << endl;
}

int main()
{
    Clock clock;
    clock.setTime(12, 00, 00);
    clock.showTime();
    return 0;
}
