c语言代码实现三子棋，可直接使用或参考的代码

本篇用c语言实现了简单的三子棋。

代码演示：

#define _CRT_SECURE_NO_WARNINGS 1

#include
#include
#include
#include

#define row 3
#define col 3

//定义棋盘静态全局变量
static char chess_board[row][col];

//初始化棋盘
void InitGame() {
	for (int i = 0;i < row;++i) {
		for (int j = 0;j < col;++j) {
			chess_board[i][j] = ' ';
		}
	}
}

//显示棋盘
void ShowChessBoard() {
	for (int i = 0;i < row;++i) {
		printf(" %c | %c | %c n", chess_board[i][0],
			chess_board[i][1],
			chess_board[i][2]);
		if (i != 2) {
			printf("--- --- ---n");
		}
	}
}

//玩家下棋
void PlayerMove() {
	int m = 0;
	int n = 0;
	while (1) {
		printf("请输入你要落子的坐标(格式为 坐标一+空格+坐标二)：");
		scanf("%d %d", &m, &n);
		if (m < 0 || m>2 || n < 0 || n>2) {
			printf("输入的坐标只能在0~2之间！n");
		}
		else if (chess_board[m][n] != ' ') {
			printf("该处已有棋子！请重新选择。n");
		}
		else {
			chess_board[m][n] = 'O';
			break;
		}
	}
}

//电脑下棋
void ComputerMove() {
	int m = 0;
	int n = 0;
	while (1) {
		srand(time(0));
		m = rand() % 3;
		n = rand() % 3;//随机生成0~2的数字
		if (chess_board[m][n] == ' ') {

			break;
		}
	}
}

//判断棋盘是否满
bool IsFullChessBoard() {

//检查结果

	InitGame();

	}

	//判断输赢

	if (r == 'O') {

	}
	else if (r == '*') {
		printf("不可能，不可能，你居然会输给它!!!n");
	}
	else {

	}
}

int main() {

	int select = 1;
	while (select) {
