Yeah, I understand that the array starts at one, but I only want to display the 3x3 set of values that is in the center of the array. The other two rows are only present to make it easier for me to use the check_neighbors function I created, so that I wouldn't have to alter it or add unnecessary ifs into it for values with less than eight neighbors, but the program still gives me the error. I was wondering more about why I might get the strange output of -858993460. Thanks again for any help.
