    Help with tables in C++

    Hi,

    How can I create a table of hex numbers and store it in memory so that I could read and write from and to the table easily? Or is it just easier to create a text file and use the I/O commands to read and write? How about just creating an array of hex numbers and going through that?

    I am looking for the simplest way possible because this is part of a bigger project.


    My table contains 4 digit hex numbers (like 123A) in each row and a total of 1024 rows all in one column.


    I am new to C++ programming and would appreciate any help.

    Thanks,

    Ryan

    It's all hex (or binary) at the machine level.
    'base' is just a convenient representation for the user. There is nothing magic about this.

    Code:
    int array[10] = { 1024, 2048 };
    is no different to
    Code:
    int array[10] = { 0x0400, 0x0800 };
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.
