这是一个三子棋小游戏的代码，其实不光可以三子棋，通过改一个数字还可以生
成五子棋八子棋等等。代码如下

游戏函数的实现

> //函数的实现#include "game.h"void InitBoard(char board[ROW][COL], int row, int col){ int i = 0; int j = 0; /*for(i=0; i<row; i++) { for(j=0; j<col; j++) { board[i][j] = ' '; } }*/ memset(&board[0][0], ' ', row*col*sizeof(board[0][0]));}void DisplayBoard(char board[ROW][COL], int row, int col){ int i = 0; for (i = 0; i<row; i++) { //printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]); //if(i<row-1) // printf("---|---|---\n"); int j = 0; for (j = 0; j<col; j++) { printf(" %c ", board[i][j]); if (j<col - 1) printf("|"); } printf("\n"); 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; int y = 0; printf("玩家走:>\n"); while (1) { printf("请输入走的坐标:>"); 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("坐标被占用，请重新输入!\n"); } } else { printf("坐标有误！\n"); } }}void ComputerMove(char board[ROW][COL], int row, int col){ int x = 0; int y = 0; printf("电脑走:>\n"); while (1) { x = rand() % row; y = rand() % col; if (board[x][y] == ' ') { board[x][y] = '#'; break; } }}static int IsFull(char board[ROW][COL], int row, int col){ int i = 0; int j = 0; for (i = 0; i<row; i++) { for (j = 0; j<col; j++) { if (board[i][j] == ' ') return 0; } } //已满 return 1;}char CheckWin(char board[ROW][COL], int row, int col){ int i = 0; for (i = 0; i<row; i++) { //判断一行是否相同 if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][0] != ' ') { return board[i][0]; } } for (i = 0; i<col; i++) { //判断一列是否相同 if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] != ' ') { return board[0][i]; } } if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ') { return board[1][1]; } if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ') { return board[1][1]; } //平局 if (IsFull(board, row, col) == 1) { return 'Q'; } //继续 return 'C';}

游戏界面

这样一个三子棋的游戏就实现了，写代码前一定要先搞清楚游戏逻辑，再一步
一步去写。
