0

My program takes numbers from a .txt file then puts it in, so that an array has a "bacteria" in it. The "bacteria" will die if it has 4 or more, or if it has 1 or less. It will live with 2-3 neighbors. If an empty cell has three neighbors, then a "bacteria" will grow and live there. I must go through five "days" of dying and growing.

I do this by moving this from one array to the next.

For some reason, I get the wrong answer for the "days"

The array is 20x20, ignoring the 0 lines.

I've tried moving it to multiple arrays and different ways, but 4 hours in, it either was worse or horrible T.T
