Your program is full of loops all over, specifically which loop are we talking about

You are incrementing the counter in one loop and printing it in another loop. After the first loop the value of counter will be 50 and you never change it so it stays like that for the rest of the program.

line 80 is the one im talking about sorry this code if for a game of life so it has a lot of loops
