c++实现五子棋_c++五子棋

思路：先用用system（“color 70”）改变控制台的背景色为灰白色，前景色为黑色，然后用“■”打印棋盘，然后用SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), a)改变输出颜色分别为白色和黑色，用字符“●”打印黑棋和白棋。
整个棋盘用一个char类型的二维数组保存，空的地方用‘ ’标识，玩家一下棋的地方用‘x’标识，玩家二下棋的地方用‘o’标识（电脑算作玩家一）。
核心代码模块在于胜负判断，如何在char类型的二维数组中找到五星连珠？

主要思路：每落一子判断一次，从这个子向前数四个向后数四个，在这九个子中从头向后查找，看是否有五个子完全相同，若有这胜利
