    Date data type?

    Hi,

    I was wondering how I can store a date in my program.

    Basically the program will work like this:

    Code:
    cout << "Enter the date of the appointment";
    cin >> ????
    I would like to store the date the user enters using some type of 'date datatype'.

    I have found how to get the current date from the host system, but I'm wanting to store future dates.

    Hope someone can advise me on how to accomplish this simply.

    Many thanks!

    I would probably use a structure or class, so then you can have different variables such as month, day, and year and they would be contained in a sort of "data type" that you defined.

    There is no built-in date type.
    What you would need to do is use the C struct tm or your own struct/class and overload operator >>.
    Otherwise, you can input into a string and parse it. But that is pretty much what you would have to do inside operator >> anyway.

    Alternatively, there is boost. They have date classes. I do not know if they have operator >>, but you could always look. Boost is usually great.

    Yep, Boost.DateTime has input/output operations. I'm not sure how flexible the parsing code is, though.
