C++ I can't update a vector from within a function

I think there's something basic I'm missing here but I have a vector of a structure I made called 'Event' called eventTable that I'm trying to access from within a function. I'm getting this error: "Invalid arguments ' Candidates are: void push_back(const Event &)" Any suggestions?

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

vector<Event> eventTable;

void createEvent(Event::TYPE type, double time){
    Event newEvent(Event::TYPE type, double time);
    eventTable.push_back(newEvent);
}

Do not include the types. You want to construct an object, not declare a function. This constructs an object:

Event newEvent(type, time);

Event newEvent(Event::TYPE type, double time);

This is not to create an object of Event class. The vector eventTable stores objects of Event, however, you are not providing objects of Event in your current way. You were declaring a function.

Try:

Event newEvent(type, time);
