C++ - 基本井字棋程序打印空白屏幕

Question

我正在用 C++ 开发一个基本的 Tic Tac Toe 游戏，因为我是初学者，但是这个函数打印出一个困惑的东西，通常要么是空白屏幕，要么是带有奇怪字符的困惑版本。代码:

#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;

}

这似乎有效:

#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;
}

我注意到您的原始代码引用了大小为 9 的数组的 [9]，该数组超出了范围(该数组中的最后一个条目将是 [8])，并且您在对齐框时包含了太多空格，因此值有点倾斜。希望这会有所帮助。
