课程设计报告-三子连珠

课程设计报告-------三子连珠理学院应用物理系912113090111 郝小龙课题要求：1.将程序改写成类。

2.将棋盘扩充成4*4。

3.统计输赢结果并打印输出。

进一步改进程序：将if else if 语句改为for 语句程序的源代码：/*第2题TICTACTOE游戏--源代码及关键源代码注解如下：*/#include <iostream.h>#include <stdlib.h>void PrintBoard(); // game boardvoid PrintInfo(); // some info about the rules of the game is printedvoid PrintStats(int, int, int);
