    Hey people,

    Something funny is happening when I write out to file. I was given a specific file format and I'm trying to get my program to generate this file format.

    The file format has three columns and multiple rows depending on how much data you gave. 1 row = 1 sample.

    I've written the code for writing to file, but when I open the file using notepad, "\n" seems not to have been interpreted as a newline, and all that is displayed is a black square where the newline should have been....

    I dont know if the problem is with the way notepad is interpreting the "\n", or if the problem is with my code?

    The file extension is .dat btw

    Thanks,
    Martin

    Hi guys.

    What's happening here is that Windows expects a new line in a text file to be written as CR-LF (carraige return, ascii 13, followed by line feed, ascii 10). In
    C this is "\r\n".

    Unix, amonst other operating systems, expects just the \n.

    Some text editors, like WordPad, or TextPad, but not Notepad, are smart enough to interpret either convention.

    So, depending on who should be using the file you may still be in trouble. Strictly, your file does not contain valid line feed characters for Windows.
