我是 C++ 的初学者，正在通过“Jumping Into C++”工作。我正在学习数组并试图将一个基本的跳棋游戏放在一起，并且我有一段时间让我的初始数组代表棋盘正常工作。特别是，第 10 行显示的值是我没想到的。我希望这些值是：
[10][2][10][2][10][2][10][2][10][2]
相反，它是：
[10][2][10][2][10][ 10 ][10][2][10][ 1 ] （突出显示未按我预期出现的两个值）。
我通过显示几个元素的值来确认第 265 和 288 行的值（标记为“//WTF？”）并得到： Space 6,10 = 0 Space 10,10 = 1
根据我用来设置初始值的“for”语句，我不明白为什么这两个值设置不正确。
感谢任何帮助！
谢谢！
