[font=helvetica, arial, verdana,]My homework is to make a c program for game of life. I have made my code already, the problem is when i'm running the code the compiler doesn't display any error, but my code still doesn't work well. I have to print in the screen an initial generation coming from a textfile, from that initial generation, I have to calculate the next generation using the rules of the game. After calculating the next generation I should save it from another textfile.[/font]

[font=helvetica, arial, verdana,]Rules of the game: [/font]

[font=helvetica, arial, verdana,]1. An organism will survive if it has exactly 2 or 3 neighbors.[/font]

[font=helvetica, arial, verdana,]2. An organism will die if it has less than 2 or more than 3 neighbors.[/font]

[font=helvetica, arial, verdana,]3. An organism will be born if it has exactly 3 neighbors.[/font]

[font=helvetica, arial, verdana,]I think I applied the rules of the game well, however I have no idea why my code still can not calculate the next generation.[/font]

[font=helvetica, arial, verdana,]I hope you guys could help me.. Thanks a lot!! by the way my board is a 25x25 matrix of the character 'X' and 'blank space'. 'X' corresponds to a living organism.[/font]

here is my code:
