我想请教一下如何将数组指针从一个头文件传递到另一个头文件。
我有一个用于井字游戏的头文件，包含了井字游戏的实现，另一个头文件将包含我的AI及其方法。
我想知道是否可以在这两个头文件之间传递游戏的走法，这样AI可以做出智能的走法，并将结果返回到井字游戏的头文件中进行验证/更新游戏棋盘（或者我在AI中再做一次验证）。一旦我有了这个想法，我就会开始将井字游戏的方法分离到它们自己的类中。
我已经包含了我的主程序、井字游戏和AI的代码。如果有任何批评，请告诉我 😊
主程序

#include <iostream> #include <iomanip> #include <string> using namespace std; class TicTacToeAI { private: TicTacToe board; int col =0; int row =0; int arr [3][3] = {0}; public: void CreateArr(int *Arr, int arrLength); void play(); void getXmove(); void getOMove(); void getXmove(char player, row&, col&); void GetoMove(char playr , row&, col&); }; void TicTacToeAI::CreateArr(int *Arr,int arrLength) { }回答：
最常见的方法可能是控制反转（Inversion of Control）。
下面的代码展示了通过依赖注入实现的控制反转（Inversion of Control by Dependency Injection）。
因此，井字游戏可以通过类成员指针访问AI。
#include<iostream>class TicTacToeAI{ };class TicTacToe{ private: const TicTacToeAI* m_AI; public: TicTacToe( const TicTacToeAI* ai ) : m_AI( ai ){ // 注入指针到井字游戏 }};int main(){ TicTacToeAI Test; TicTacToe run( &Test ); run.Play();}
