停留在TicTacToe檢查移動是否有效C++

嗨，我是一個初學者，我正在做一個控制檯tic tac腳趾C++，然後我嘗試在unity3d中完成它，但這是另一個故事，我卡在get_move1（）函數，至於如何檢查數組是否有1或-1，如果它是滿的，並且函數應該說是無效移動，除了2d數組之外，這可以通過任何其他方式完成，我的程序只是掛起沒有錯誤，我還沒有在其他功能上工作，所以他們現在只是空的。謝謝你的幫助。停留在TicTacToe檢查移動是否有效C++

#include <iostream> 

using namespace std; 

//declare global variables 

int board_state[3][3] = { {0,0,0}, //here the 2d array is initialized and set to 0 for empty 
          {0,1,0}, 
          {0,0,0} }; 

char gui_state[3][3];    //2d array to represent the X and O on the board 




//declare functions

void get_move1(); 



int main() 
{ 
    init_board(); 
     get_move1(); 
} 

void init_board() 
{ 
    cout << " 1 | 2 | 3 \n" 
      "  | | \n" 
      " - - - - - - \n" 
      " 4 | 5 | 6 \n"

} 

void get_move1() // In this function player's moves are taken and make sure they are valid if so update arrays 
{ 
    int player1_move; 
    int i; 
    int j; 
    bool invalid_move; 


    cout << "Player 1 enter move" << endl; 
    cin >> player1_move; 

    //need to check if the players's move is valid 

    for (i=0; i < 3; i++)   //if array is 1 or -1 then move is invalid 
    { 
     for(j = 0; j < 3; i++) 
      if (board_state[i][j] == 1 || board_state[i][j] == -1) 
      { 
       invalid_move = true; 
      } 


    } cout << "You entered an invalid move" << endl; 

} 

void get_move2() 
{ 

} 

void game_state() 
{ 

} 

void check_win() 
{ 

}

，所以我決定去一個維數組來保持它的簡單，現在

int board_state[9] = {0,1,0,0,0,0,0,0,0}; //here the 1d array is initialized and set to 0 for empty 

void get_move1() // In this function player's moves are taken and make sure they are valid if so update arrays 
{ 
    int player1_move; 
    int array_index; 
    int player1_fill = 1; 


    cout << "Player 1 enter move" << endl; 
    cin >> player1_move; 

    //need to check if the players's move is valid 

    array_index = player1_move -1; 

    if (board_state[array_index] == 1 || board_state[array_index] == -1) 
    { 
     cout << "Invalid move" << endl; 
    } 

    else board_state[array_index] = player1_fill;

感謝您的幫助球員。

這條線：

for(j = 0; j < 3; i++)

應該是：

invalid_move不正確intialized

此外，如果細胞被標記1.9 ..你需要映射它（我， j）正確並更新數組。您未更新陣列player1_move。爲此，您不需要在for循環在所有

所以我改變了invalid_move = false;是的，一旦移動有效，我還沒有那麼遠，那麼我的下一步就是更新數組 – kodaman

'invalid_move'確實已正確初始化。在C++中，所有的左值都是默認初始化的，默認的ctor，也就是說，標量是零賦值，所以它被聲明爲false。閱讀C++標準的第8.5節。 – moshbear

的for循環後添加以下代碼：

if (invalid_move) 
{ 
    cout << "Invalid move.\n"; 
}

是的，我只是補充說，在我認爲2D陣列只是我的聯盟的方式，我會代表一切在1D陣列 – kodaman

被發現不合適的舉動後的問題，循環不停止，因此invalid_move被覆蓋。

invalid_move=false;//and here 
for (i=0; i < 3&&invalid_move==false; i++) //Watch out here 
    { 
     for(j = 0; j < 3&&invalid_move==false; j++) 
      if (board_state[i][j] == 1 || board_state[i][j] == -1) 
      { 
       invalid_move = true; 
      } 


    } cout << "You entered an invalid move" << endl;
