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.
