C++ - 基本井字棋程序打印空白屏幕

Question

我正在C++中使用基本的井字遊戲遊戲，因爲我是初學者，但是這個函數打印出一個亂七八糟的東西，通常是空白屏幕或與奇數字符混淆的版本。 代碼：

#include <iostream> 
#include <string> 

void printboard() 
{ 
    std::string array[9] = {"O","O","O","O","O","O","O","O","O"}; 


    std::cout << " |  | " << std::endl; 
    std::cout << " "; std::cout << array[2]; std::cout << " | ";      std::cout << array[4]; std::cout << " | "; std::cout << array[3]; std::cout << " " << std::endl; 
    std::cout << " |  | " << std::endl; 
    std::cout << "----|-----|----" << std::endl; 
    std::cout << " "; std::cout << array[5]; std::cout << " | ";   std::cout << array[1]; std::cout << " | "; std::cout << array[3]; std::cout << " " << std::endl; 
    std::cout << " |  | " << std::endl; 
    std::cout << "----|-----|----" << std::endl; 
    std::cout << " "; std::cout << array[7]; std::cout << " | ";    std::cout << array[9]; std::cout << " | "; std::cout << array[8]; std::cout << " " << std::endl; 
    std::cout << " |  | " << std::endl; 
    std::cout << " |  | " << std::endl; 

}

這似乎工作：

#include <iostream> 
#include <string> 

void printboard() 
{ 
    std::string array[9] = { "O","O","O","O","O","O","O","O","O" }; 

    std::cout << " |  | " << std::endl; 
    std::cout << " "; std::cout << array[2]; std::cout << " | "; std::cout << array[4]; std::cout << " | "; std::cout << array[3]; std::cout << " " << std::endl; 
    std::cout << " |  | " << std::endl; 
    std::cout << "----|-----|----" << std::endl; 
    std::cout << " |  | " << std::endl; 
    std::cout << " "; std::cout << array[5]; std::cout << " | "; std::cout << array[1]; std::cout << " | "; std::cout << array[3]; std::cout << " " << std::endl; 
    std::cout << " |  | " << std::endl; 
    std::cout << "----|-----|----" << std::endl; 
    std::cout << " |  | " << std::endl; 
    std::cout << " "; std::cout << array[7]; std::cout << " | "; std::cout << array[6]; std::cout << " | "; std::cout << array[8]; std::cout << " " << std::endl; 
    std::cout << " |  | " << std::endl; 
} 

int main() 
{ 
    printboard(); 
    std::system("Pause"); 

    return 0; 
} 

我注意到，你原來的代碼中引用[9]大小9的陣列，這是出界（的該數組中的最後一個條目是[8]），並且在對齊方框時包含了太多的空格，所以這些值有些偏斜。希望這可以幫助。
