    Kernell32.dll Error

    hey all...this code compiles and runs correctly...all except a Kernell32.dll error that pops up during the run. Anyone see
    a pile of dlls on the stack inappropriately that would cause this?
    (It's one of my early 2d array progs that i did in my 1st class).
    I never was able to debug the error out.
    thanks a bunch, it may teach me something about how to trouble-shoot these and other errors

    no errors

    i don't get any errors.
    the program compiles perfectly AND my output is perfect...
    except when it is writing to the outfile (or even if I cout it to the screen) i get this error:

    http://scuba22.freeyellow.com/1.JPG

    i say OK and the program continues to run and finish...


    this is the data from my infile :
    1 29 38 94 50 67
    37 899 10 119 121 138
    11 15 203 401 222 109
    2 94 55 5 35 21

    what do you think?
    thanks alot

    You have to give it both dimensions when you declare the array.
    int arr2d[krows][kcols]={0};
    Another option is to declare it dynamically.
