    C++ File I/O Help

    Ok so im working on a project... here are the specs:

    I'm given a data.txt file with the following info:


    0 || person_name || status

    the 0 represents a number between 0-228 (not all the numbers in between)... basically this number is an "Arrival time" (this program is a simulation)..

    The status field is tells what kind of person they are (specificly alumni , etc)

    Basically my question is this... how do I read in data from a outside source? I want to store the numbers into an array, the name into a seperate array, and finally the status in another. (3 arrays)... How do I do that?


    The specific assignment im trying to work on is located here:
    http://www.cs.unt.edu/~roden/courses/3400/homework2.txt
    and the data file is here:
    http://www.cs.unt.edu/~roden/courses/3400/hm2_data.txt


    thank you for your time.

    As one of the views, I feel obliged to defend my choice not to reply. You're problem is both uninteresting and common. That combination is good for being ignored as you can find your answer with a board search. I'm also sure plenty of people will reply to inform you of that.

    char *buf = new char[MAX_LEN];

    ifstream data.open("test".txt);
    data.getline(buf);

    data.close()

    delete buf;

    That is very basic, and some of the syntax might be a bit off. But it will give you something to read into.

    I didn't think you were.

    That wasn't my point. My point was that if you searched the boards before starting a new thread, you would have found your answer.
