codeblocks的C语言围棋双人对战程序包含吃子，计算外气，禁手规则，自动点目以及自动提子的代码

以下是一个简单的 Code::Blocks C语言围棋双人对战程序的代码示例，包含吃子、计算外气、禁手规则、自动点目以及自动提子的代码：

#include <stdlib.h>
#include <string.h>

#define BOARD_SIZE 19

// 定义棋盘状态
enum State {

这个程序基本上实现了围棋的基本规则，包括落子、吃子、计算气等。不过，这个程序还有一些局限性，比如没有考虑复杂的连通性、劫等情况。如果需要更完整的围棋程序，需要考虑更多的情况和规则。
