C++ 在结构构造函数中设置枚举字段时遇到问题

Question

我试图在结构构造函数中设置一个枚举，但我无法完全正确地获得语法。有什么建议吗？这就是我所拥有的，但我不断收到错误。

struct Event{
    enum eventType { Arrival, CPUburstCompletion, IOcompletion, TimerExpired }enumField;
    double time; // Defined as time units since the start of the simulation

    Event(eventType e, double theTime): enumField(e), time(theTime){}
};

Answer 1

也许……

struct Event {
  enum TYPE {
    Arrival,
    CPUBurstCompletion,
    IOCompletion,
    TimerExpired
  };
  double time;  
  TYPE type;  
  Event(Event::TYPE type, double time)
      : type(type),
        time(time) { }
};

int main() {
  Event e(Event::Arrival, 1.0);
  return 0;
}
