Read data from file and put into vector

Hi everyone. I'm new to this board and am just starting to learn C++. I'm having difficulties with part of a problem I'm trying to solve. I need to read data from a file, which contains integers representing date and time, and insert the data into a vector.

My data file for appointments are layed out like so, representing month day year hour minute:

05 16 2012 09 00
08 30 2011 10 30

My elementary vector so far looks like this:

vector<Appointment*> fileData;
fileData[0] = new Appointment(read_month_data_from_file, read_day_data_from_file, read_year_data_from_file, read_hour_data_from_file, read_minute_data_from_file);

I've added the read_ parts to represent where the data needs to be transfered into.

Any help would be greatly appreciated. Thanks for the time and help in advance.

Overload the >> Operator for Appointment and get the values like you do with std::cin, only replacing it with the name of your object.

Thanks for the reply manasij. I'm not seeing how that helps solve my problem (I'm new, so I'm most likely not making the connection properly).

So I need to get data from:
ifstream input_data;
input_data.open("appointments.txt");

And put that data into:
vector<Appointment*> fileData;
fileData[0] = new Appointment(read_month_data_from_file, read_day_data_from_file, read_year_data_from_file, read_hour_data_from_file, read_minute_data_from_file);

Do you really need to store Appointment pointers? Why not use a std::vector<Appointment> instead? If you do have a good reason to use pointers, why not use a std::vector<std::shared_ptr<Appointment>> or std::vector<std::unique_ptr<Appointment>> instead?

One problem is that you need to actually create the element in the vector, e.g., by using push_back.

Code:

---

int m, d, y, h, n;
while (input_data >> m >> d >> y >> h >> n)
        fileData.push_back(new Appointment(m, d, y, h, n));
