三子棋代碼

這是一個三子棋小游戲的代碼，其實不光可以三子棋，通過改一個數(shù)字還可以生
成五子棋八子棋等等。代碼如下

頭文件

> #define _CRT_SECURE_NO_WARNINGS 1

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

//函數(shù)的聲明
#define ROW 3    //行列數(shù)為幾就是幾子琪
#define COL 3    

void InitBoard(char board[ROW][COL], int row, int col);
void DisplayBoard(char board[ROW][COL], int row, int col);
void PlayerMove(char board[ROW][COL], int row, int col);
void ComputerMove(char board[ROW][COL], int row, int col);

//
//玩家贏-*
//電腦贏-#
//平局---Q
//繼續(xù)---C
//
//判斷游戲輸贏的

游戲界面

    printf("*********************\n");
    printf("***   1. play     ***\n");

    while (1)
    {

        DisplayBoard(board, ROW, COL);//打印棋盤
        //判斷輸贏

        {

//游戲的測試

    int input = 0;
    srand((unsigned int)time(NULL));

    do
    {
        menu();
        printf("請選擇:>");
        scanf("%d", &input);
        switch (input)
        {

這樣一個三子棋的游戲就實現(xiàn)了，寫代碼前一定要先搞清楚游戲邏輯，再一步
一步去寫。
