hello all!

i need help regarding my C programming homework of the Conway's game of life.

i have to make a C program that will read a textfile containing a 25x25 matrix of 'X' or 'blank space' and will print its content. This will serve as the initial generation and will be the basis of the calculations for the next 2 generations. Then I have to save the calculated next generations into another textfile using the same program.

Rules of the Game

The next generation of organisms is determined according to the follow-

ing criteria:

• Birth – An organism will be born in each empty location that has

exactly three neighbors.

• Death – An organism with four or more organisms as neighbors will

die from overcrowding. And organism with fewer than two neighbors

will die from loneliness.

• Survival – An organism with two or three neighbors will survive to the

next generation.

this is the code i have done so far and it isn't working yet, i posted the code together with the error displayed by the compiler..

please please do help me. :(
