c++ - 如何通过另一个构造函数传递构造函数

Question

我有日期和时间类(class)。我正在使用公共(public)构造函数创建一个类 Onetime，但我不确定如何创建新的内联日期和时间。

schedule[0]= new Onetime("see the dentist", 
  Date(2013, 11, 4), 
  Time(11, 30, 0), 
  Time(12, 30, 0));

class Onetime {
  public: 
    Onetime(  // what should I put here?  )
}

Answer 1

这是标准方法

class Onetime {
    std::string description;
    Date date;
    Time from_time;
    Time to_time;

    Onetime(const std::string& description,
            const Date& date,
            const Time& from_time,
            const Time& to_time)
    : description(description),
      date(date),
      from_time(from_time),
      to_time(to_time)
    {
       ... rest of initialization code, if needed ...
    }
  ...
};
