学习C语言，开发三子棋小游戏

开发三子棋小游戏是学习C语言的绝佳入门项目。这款小游戏不仅能锻炼编程基础，还能激发逻辑思维能力。以下是从头到尾的开发过程和心得体会。

1.1 创建头文件

首先，建立一个头文件game.h，用以声明游戏所需的函数接口。文件内容如下：

#define ROW 3#define COL 3#include 
   
    #include 
    
     #include 
     
      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);// 定义游戏状态// 玩家赢 '*'，电脑赢 '#’，平局 'Q'，游戏继续 'C’char IsWin(char board[ROW][COL], int row, int col);

1.2 创建C源文件

接下来，编写C源文件game.c，实现上述接口的功能。文件内容如下：

#include "game.h"#include 
   
    #include 
    
     void DisplayBoard(char board[ROW][COL], int row, int col) {    int i = 0;    for (i = 0; i < row; i++) {        // 打印一行的数据        int j = 0;        for (j = 0; j < col; j++) {            printf(" %c ", board[i][j]);            if (j < col - 1) {                printf("|");            }        }        printf("\n");        // 打印分割行        if (i < row - 1) {            for (j = 0; j < col; j++) {                printf("---");                if (j < col - 1) {                    printf("|");                }            }            printf("\n");        }    }}void PlayerMove(char board[ROW][COL], int row, int col) {    int x = 0, y = 0;    printf("Player play chess\n");    while (1) {        scanf("%d%d", &x, &y);        if (x >= 1 && x <= row && y >= 1 && y <= col) {            if (board[x - 1][y - 1] == ' ') {                board[x - 1][y - 1] = '*';                break;            } else {                printf("The coordinate is occupied!\n");            }        } else {            printf("Coordinate do not match, please re-enter!\n");        }    }}void ComputerMove(char board[ROW][COL], int row, int col) {    int x = 0, y = 0;    printf("Computer play chess\n");    while (1) {        x = rand() % row;        y = rand() % col;        if (board[x - 1][y - 1] == ' ') {            board[x - 1][y - 1] = '#';            break;        }    }}int IsFull(char board[ROW][COL], int row, int col) {    int i = 0, j = 0;    for (i = 0; i < row; i++) {        for (j = 0; j < col; j++) {            if (board[i][j] == ' ') {                return 0;            }        }    }    return 1;}char IsWin(char board[ROW][COL], int row, int col) {    // 判断横三行    for (int i = 0; i < row; i++) {        if (board[i][0] == board[i][1] && board[i][1] == board[i][2] &&            board[i][0] == board[i][2] && board[i][1] != ' ') {            return board[i][1];        }    }    // 判断竖三列    for (int i = 0; i < col; i++) {        if (board[0][i] == board[1][i] && board[1][i] == board[2][i] &&            board[0][i] == board[2][i] && board[1][i] != ' ') {            return board[1][i];        }    }    // 判断对角线    if (board[0][0] == board[1][1] && board[1][1] == board[2][2] &&        board[0][0] == board[2][2] && board[1][1] != ' ') {        return board[1][1];    }    // 判断平局    if (IsFull(board, row, col)) {        return 'Q';    }    return 'C';}

1.3 测试文件

编写测试文件test.c，用于运行游戏的主程序。文件内容如下：

#include "game.h"#include 
   
    #include 
    
     #include 
     
      void menu() {    printf("-------------TIC-TAC-TOC GAME--------------\n");    printf("-------1.Play Game------------0.Sign out-------\n");    printf("-------------------------------------------\n");}void game() {    char ret = 'C';    char board[ROW][COL] = {0};    InitBoard(board, ROW, COL);    DisplayBoard(board, ROW, COL);    while (1) {        PlayerMove(board, ROW, COL);        DisplayBoard(board, ROW, COL);        ret = IsWin(board, ROW, COL);        if (ret != 'C') {            break;        }        ComputerMove(board, ROW, COL);        DisplayBoard(board, ROW, COL);        ret = IsWin(board, ROW, COL);        if (ret != 'C') {            break;        }    }    if (ret == '*') {        printf("The player won!\n");    } else if (ret == '#') {        printf("Computer won!\n");    } else {        printf("It ends in a draw!\n");    }}void test() {    int start = 0;    srand((unsigned int)time(NULL));    do {        menu();        printf("Please choose whether to start the game\n");        scanf("%d", &start);        switch (start) {            case 1:                game();                break;            case 0:                printf("----------Sign out game-----------\n");                break;            default:                printf("----------Choose Again-----------\n");                break;        }    } while (start);}int main() {    test();    getchar();    getchar();}
