    Put into an array

    I have a database which has quite a few entries which looks like this:

    module 1¦version 1¦description 1¦command 1
    module 2¦version 2¦description 2¦command 2

    I used the ¦ character to split the different sections.

    What I am unable to do is read from this database and take everything up until the first ¦ char and put that in an array. Then ignore the ¦ char and take everything up until the next ¦ char and put it into another array and so forth.

    Any ideas how to do this or am I going about this in the wrong way?

    A database or a file?

    If it's a file, then you can read a line and tokenize it using strtok().

    You could also use istream.get() to read one character at a time, and then just ignore the '|'.

    The long way around the horn.
    Code:
    int ch;
    
    while((ch = ifstream_var.peek()) != EOF)
    {
         if(ch == '|')
             take an action
          
         ifstream_var.your_get_method
    }
    I haven't used a compiler in ages, so please be gentle as I try to reacclimate myself. :P

    Kay I'm real confused. I've never worked with reading something from a file before.

    It's the same as reading from cin except you have to open the stream yourself.
    My best code is written with the delete key.
