Using this Code please write code that correctly updates a board of conways game of life by using the func "update" that takes in an int, size, and two boards, one being the old and one being the new. Besides that, everything is pretty straight forawrd. /* * C program for Conway's ``game of life''. * * Command-line arguments specify input file and number of steps. * * Input file contains a representation of an initial board configuration: * N (size of board) and N*N values (each 0 or 1). */ #include  #include  #include  #include  /* * builds 2D array in form of an array of pointers into one big 1D array. * return value is array of pointers, or NULL if there was a problem * (in which case the function prints a suitable error message). */ bool **build2D(long size); /* * frees 2D array, built as in build2D(). */ void free2D(long size, bool **array2D); /* * reads initial board configuration from file. * builds 2D array in form of an array of pointers into one big 1D array. * parameters: * infile is an already-opened file. * (out) *size_p is board size * return value is array of pointers, or NULL if there was a problem * (in which case the function prints a suitable error message). */ bool **read_board(FILE* infile, long *size_p); /* * generates new board configuration from old. */ void update_board(long size, bool **old_board, bool **new_board); /* * prints board. */ void print_board(long size, bool **board); /* * main program */ int main(int argc, char* argv[]) { /* process command-line arguments */ if (argc != 3) { fprintf(stderr, "parameters; infile num_steps "); return EXIT_FAILURE; } FILE* infile = fopen(argv[1], "r"); if (infile == NULL) { fprintf(stderr, "unable to open input file %s ", argv[1]); return EXIT_FAILURE; } char* end_ptr_for_strtol; long steps = strtol(argv[2], &end_ptr_for_strtol, 10); if ((*end_ptr_for_strtol != '\0') || (steps < 0)) { fprintf(stderr, "invalid num_steps "); return EXIT_FAILURE; } /* create board from input file */ long size; bool **board = read_board(infile, &size); if (board == NULL) { fclose(infile); return EXIT_FAILURE; } fclose(infile); /* create second board to use for updates */ bool **new_board = build2D(size); if (new_board == NULL) { free2D(size, board); return EXIT_FAILURE; } /* print initial configuration */ printf("Initial board: "); print_board(size, board); putchar(' '); /* loop to update board and print */ for (long step = 1; step <= steps; ++step) { /* update (results in new_board) */ update_board(size, board, new_board); printf("Board after step %ld: ", step); print_board(size, new_board); putchar(' '); /* swap old and new boards by exchanging pointers(!) */ bool **temp = board; board = new_board; new_board = temp; } /* tidy up and return */ free2D(size, board); free2D(size, new_board); return EXIT_SUCCESS; } /* * functions (described above) */ bool **build2D(long size) { bool *data = malloc(size * size * sizeof(data[0])); if (data == NULL) { fprintf(stderr, "unable to allocate space for board of size %ld ", size); return NULL; } bool **array2D = malloc(size * sizeof(array2D[0])); if (array2D == NULL) { fprintf(stderr, "unable to allocate space for board of size %ld ", size); return NULL; } for (long r = 0; r < size; ++r) { array2D[r] = &data[r*size]; } return array2D; } void free2D(long size, bool **array2D) { bool *data = array2D[0]; free(data); free(array2D); } bool **read_board(FILE* infile, long *size_p) { /* read size from input file */ long size; if ((fscanf(infile, "%ld", &size) != 1) || (size <= 0)) { fprintf(stderr, "invalid size in input file "); return NULL; } *size_p = size; /* build 2D array */ bool **board = build2D(size); if (board == NULL) { return NULL; } /* fill with data from file */ int inchar; for (long i = 0; i < size; ++i) { for (long j = 0; j < size; ++j) { /* get next nonspace character from input file */ while (isspace(inchar = fgetc(infile))) { } if (inchar == '1') { board[i][j] = true; } else if (inchar == '.') { board[i][j] = false; } else { fprintf(stderr, "unable to read values for board "); free2D(size, board); return NULL; } } } /* check for anything else in input file */ while (isspace(inchar = fgetc(infile))) { } if (!feof(infile)) { fprintf(stderr, "unable to read values for board "); free2D(size, board); return NULL; } return board; } void update_board(long size, bool **old_board, bool **new_board) { /* FIXME your code goes here */ } void print_board(long size, bool **board) { for (long i = 0; i < size; ++i) { for (long j = 0; j < size; ++j) { if (board[i][j]) printf("1 "); else printf(".
