    Compile/ runs on MAC but not on Windows?

    This code works beautifully on my Macbook (where I compiled it and it runs perfectly). However when I run it on a windows machine, it compiles but reads that the process died on "Signal 11"

    We use JGrasp in our class for everything, and I cannot find out why it wont work. I recieved a 52/100 on the assingment because it didn't work for my grader and need help disputing it. Finding out why it didnt run would hopefully be a step as to figuring out why it doesnt work.
    These are the files
    auResults2013.txt
    assign10.c

    Thanks in advance!!!!!!

    Code:

    It seems the formatting of your text is a little messed up. I would fix that first. For example, the spacing in the left column has been replaced by garbage characters. If you're pasting code here you need to just paste plain text without any rich text formatting.

    Just because it worked on one machine does not mean it's correct.

    In your case, you've forgotten to initialize l (bad variable name, by the way, since it looks like a 1) to 0 when reading in the lines. Apparently on the Mac system it happened to be 0 but on the MS system you weren't so lucky. Welcome to the wacky world of programming!

    Also, many of your lines are tooooooooooooooooooooooooooooo long; try to limit them to 80 chars or less.

    There are more unitialised variables than l. Consider what happens when there is no input file, for example.

    Actually, we don't have to imagine it we can just run it
