如何從文本文件中獲取值並將其輸入到二維數組中？ C++

Question

輸入：

Text File Values: 1 1 A 2 2 B 3 3 C 0 0 X 

輸出：

3 TILES on Scrabble Board 

ROW COL LETTER 
=== === ====== 
1 1 A 
2 2 B 
3 3 C 
=== === ====== 


4 x 4 SCRABBLE BOARD 


     1 2 3 4 
     + - - - - + 
row1=> | A  | 
row2=> | B  | 
row3=> |  C | 
row4=> |   | 
     + - - - - + 
     1 2 3 4 

（1）存儲所有板字符到陣列

char Board[9][9]; // Capacity is 9x9 = 81. 

RULE：板單元格可以包含至多一個值; 顯示錯誤時的消息： - 所述細胞已包含標記 - 該標記不是一個字母 - 行超出範圍[1，boardsize] - 鞍部在該範圍之外[1，boardsize]

ERROR: REJECTED CELL <row> <col> <symbol> CELL MARKED 
ERROR: REJECTED CELL <row> <col> <symbol> NOT A LETTER 
ERROR: REJECTED CELL <row> <col> <symbol> BAD ROW 
ERROR: REJECTED CELL <row> <col> <symbol> BAD COL 

（2）讀取輸入文件後，顯示電路板陣列。 （僅圖示）

（3）顯示在scrable板的話：

HORIZONTAL: xxxx yyyyyyy zzzzz 3 WORDS 
VERTICAL: aaa bbb ccc ddd 4 WORDS 
7 SCRABBLE WORDS 

問題：如何輸入文件的值例如：11.一種成char板[9] [9]？我想11代表ROW和COL和符號A要與1 1

實例相關聯：

Board[1][1] = A 
Board[2][2] = B 

新代碼：

int main() 
{ 
    //-------------------------------------------- -------------------------- 
    // Declare variables 
    //---------------------------------------------------------------------- 
    char filename[80]; 
    int boardsize, row, col; 
    char symbol; 
    char Board[9][9]; 
    ifstream inF; 

    //-| ---------------------------------------------------------------------- 
    //-| Print the copyright notice declaring authorship. 
    //-| ---------------------------------------------------------------------- 
    cout << endl << "(c) 2017, twilson" << endl << endl; 


    //-| ---------------------------------------------------------------------- 
    //-| 1. Get file name and open file. 
    //-| ---------------------------------------------------------------------- 
    cout << "Enter name of input file: "; 
    cin >> filename; 
    cout << endl; 

    inF.open(filename); 
    if (inF.fail()) 
    { 
     cout << "FATAL ERROR: Can not open file " << "'" << filename << "'" << endl; 
     exit(1); 
    } 

    //-| ---------------------------------------------------------------------- 
    //-| 2. Get board size. 
    //-| ---------------------------------------------------------------------- 
    cout << "Enter board size [1-9]: "; 
    cin >> boardsize; 
    cout << endl; 

    //-| ---------------------------------------------------------------------- 
    //-3. Read in file values and output ROW, COL, and LETTER on scrabble board. 
    //-| ---------------------------------------------------------------------- 
    int T = 0; 
    int nextLine = 0; 
    int Tiles = 0; 


    // Read in file and count each tile 

    int a = 0; 
    while(inF >> row >> col >> symbol) 
    { 
     if(row > 0 && col > 0) 
     { 
      if(row == row && col == col) 
      { 
       cout << "REJECTED CELL " << row << " " << col << " " 
        << symbol << " CELL MARKED" << endl; 
      } 
      else if(!isalpha(symbol)) 
      { 
       cout << "REJECTED CELL " << row << " " << col << " " 
        << symbol << " NOT A LETTER" << endl; 
      } 
      else if(row > boardsize) 
      { 
       cout << "REJECTED CELL " << row << " " << col << " " 
        << symbol << " BAD ROW" << endl; 
      } 
      else if(col > boardsize) 
      { 
       cout << "REJECTED CELL " << row << " " << col << " " 
        << symbol << " BAD COL" << endl; 
      } 

      else 
       Tiles++; 
     } 

     } 

Answer 1

項目2和3中，你之間以初始化您的電路板（讓您可以稍後或檢查的地方標記爲不

for (int i = 0; i < boardsize; i++) 
     for (int j = 0; j < boardsize; j++) 
      Board[i][j] = ' '; 

while循環應該像THI S（實際打印錯誤刪除 - 僅confditions左）

while (inF >> row >> col >> symbol) 
    { 
     if(row == 0 && col == 0 && symbol == 'X'){ 
      //end condition? - not clear from your explanation 
      break; 
     } 
     if (row < 1 || row > boardsize) 
     { 
      // BAD ROW error 
     } 
     else if (col <1 || col > boardsize) 
     { 
      // BAD COL error 
     } 
     else if (!isalpha(symbol)) { 
      //NOT A LETTER error 
     } 
     else if (Board[row - 1][col - 1] != ' ') //This check requires the Board to be properly initialized 
     { 
      //CELL MARKED error 
     } 
     else { 
      //All is good 
      Board[row - 1][col - 1] = symbol; 
      Tiles++; 
     } 
    }
