Question

我在完成这项任务时遇到了麻烦。我应该创建minesweeper-ish数组。它读入一个文件：

第一行是板数（100），第二行是板上炸弹的数量。 2个整数线分别是炸弹位置的行和列。

我的问题是它只能打开一块板子而我的第二个问题是如何将9切换到板子中的*？

谢谢你！

int main() {

    FILE *fp;

    fp = fopen("mine.txt","r");

    int numberBoards = 0;
    int numberMines  = 0;
    int col;
    int row;
    int currentBoard = 0;

    // first row is going to be the number of boards
    fscanf(fp,"%d",&numberBoards);

    while ( fscanf(fp,"%d",&numberMines) > 0 ) {
            int i,j;
            // start board with all zeros
            int board[BOARD_SIZE][BOARD_SIZE] = { {0} };

            currentBoard++;
            printf("Board #%d:\n",currentBoard);

            //Read in the mines and set them
            for (i=0; i<numberMines; i++) {
                    fscanf(fp,"%d %d",&col,&row);
                    board[col-1][row-1] = BOMB;
            }

                                    //Square to the left
                                    if (j > 0 && board[i][j-1] != BOMB) {
                                            board[i][j-1]++;
                                    }
                                    //Square to the right
                                    if (j < 0 && board [i][j+1] !=BOMB){
                                            board [i][j+1]++;
                                    }

                                    //Square to the top
                                    if (i > 0 && board [i-1][j] !=BOMB) {
                                            board [i-1][j]++;
                                    }

                                    //Square to the bottom
                                    if ( i < 0 && board [i+1][j] !=BOMB){
                                            board [i+1][j]++;
                                    }


                    }



            }

            //Print out the minesweeper board
            for (i=0; i<BOARD_SIZE; i++) {
                    for (j=0; j<BOARD_SIZE; j++) {
                            printf("%d ",board[i][j]);
                    }
                    printf("\n");
            }
            printf("\n");
    }
    //Close the file.
    fclose(fp);

    return 0;
}
}

Answer 1

fclose和return不应该在while循环中 - 这就是为什么它只创建一个主板。

Answer 2

我不明白你关于打印多个电路板的问题。要打印*而不是9：

if ( board[i][j] == 9 ) printf("* ");
else printf("%d ",board[i][j]);

从文件中读取以创建阵列扫雷代码
