Tic Tac Toe陣列錯誤字符

-2

截圖說明了這一切，我使用的字符已正確放入數組中。但是，其他一些隨機字符也會插入到數組中。我很困惑！Tic Tac Toe陣列錯誤字符

main.cpp中：

#include "Players.h" 
#include "GameLayout.h" 
#include "Game.h"

#include <string> 

using namespace std; 

int main() 
{ 
    char gameBoard [3][3]; 
    cout << "**** Welcome to Leviathan's first TicTacToe Game! ****\n\n"; 
    Players playersObject; 
    playersObject.getPlayersNames(); 
    playersObject.printPlayersNames(); 
    GameLayout gameObject; 
    gameObject.printLayout(); 
    Game gamestartObject; 
    gamestartObject.gameStart(gameBoard); 
}

請調試它，然後自己刪除所有的代碼，並把僅有[MCVE]因此獲得** **明確爲讀者_where_和_what_是錯誤 –

@ FirstStep對不起，我會在下次試試！ – Leviathan

本地函數中的非靜態變量，像例如gameBoard，未初始化。您需要明確初始化它，否則其內容將爲不確定並且讀取它的值將導致未定義的行爲。

你可以簡單地做它像

char gameBoard [3][3] = { ' ' };
