三子棋,也就是井字棋。構(gòu)思游戲大致模塊,再一一實現(xiàn)每個函數(shù),首先創(chuàng)建test.c用于創(chuàng)建初始界面
1.1 進入游戲

{
int input = 0;
do {
menu();
printf("請選擇->");
scanf("%d", &input);
switch (input)
{
case 1:
printf("開始游戲\n");
game();
break;
case 0:printf("退出游戲\n");
break;
default:
printf("選擇錯誤,請重新選擇\n");
break;
}
} while (input);
return 0;
}
1.2游戲菜單
void menu()
{
printf("*****************************\n");
printf("****** 1. play ******\n");
printf("****** 0. exit ******\n");//0為假,用于終止循環(huán)
printf("*****************************\n");
}
1.3游戲的實現(xiàn)
void game()
{
char board[ROW][COL] = { 0 };//創(chuàng)建一個數(shù)組用于存放玩家和電腦下的棋
InitBoard(board, ROW, COL);//初始化棋盤
DisplayBoard(board, ROW, COL);//顯示棋盤
char ret;
while (1)
{
PlayerMove(board, ROW, COL);//玩家下棋
DisplayBoard(board, ROW, COL);
ret = is_win(board, ROW, COL);
if (ret != 'C')//判斷棋盤是否滿
break;
ComputerMove(board, ROW, COL);//電腦下棋
DisplayBoard(board, ROW, COL);
ret = is_win(board, ROW, COL);
if (ret != 'C')
break;
}
if (ret == '*')
printf("玩家贏\n");
else if (ret == '#')
printf("電腦贏\n");
else if (ret == 'Q')
printf("平局\n");
}
二、創(chuàng)建存放頭文件的文件創(chuàng)建game.h用于存放頭文件并且聲明自定義函數(shù)
#define ROW 3
#define COL 3
#include#include#include//函數(shù)的聲明
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);
char is_win(char board[ROW][COL], int row, int col);
三、游戲主體的實現(xiàn)創(chuàng)建game.c用于實現(xiàn)游戲主體
3.1 初始化棋盤函數(shù)void InitBoard(char board[ROW][COL], int row, int col)
{
for (int i = 0; i< row; i++)
{
for (int j = 0; j< col; j++)
{
board[i][j] = ' ';
}
}
//或者memset(&board[0][0],' ',row*col*sizeof(board[0][0]));(注意需要包含頭文件string.h)
}
3.2打印棋盤函數(shù)void DisplayBoard(char board[ROW][COL], int row, int col)
{
for (int i = 0; i< row; i++)
{
for (int j = 0; j< col; j++)
{
printf(" %c ", board[i][j]);
if (j< col - 1)
printf("|");//打印分割列
}
printf("\n");
if (i< row - 1)
for (int j = 0; j< col; j++)
{
printf("---");//打印分割行
if (j< col - 1)
printf("|");
}
printf("\n");
}
}
3.3 玩家下棋函數(shù)void PlayerMove(char board[ROW][COL], int row, int col)
{
int x = 0, y = 0;
printf("玩家下棋\n");
printf("請輸入坐標->");
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] = '*';
else
printf("坐標被占用,請重新輸入\n");
}
else
printf("坐標非法,請重新輸入\n");
}
3.4 電腦下棋函數(shù)由于電腦下棋是隨機的,因此需要用rand函數(shù)實現(xiàn),而rand函數(shù)和srand配套使用,后面會把srand函數(shù)放置在主函數(shù)中
void ComputerMove(char board[ROW][COL], int row, int col)
{
int x = 0, y = 0;
printf("電腦下棋->\n");
while (1)//如果生成的隨機位置未被占用,電腦下棋,否則重新生成
{
x = rand() % row;
y = rand() % col;
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}
3.5 判斷輸贏函數(shù)char is_win(char board[ROW][COL], int row, int col)
//玩家贏,返回'*'
//電腦贏,返回'#'
//平局,返回'Q'
//繼續(xù),返回'C'
{
for (int i = 0; i< row; i++)//判斷行
{
if (board[i][0] == board[i][1] && board[i][2] == board[i][1] && board[i][0] != ' ')
return board[i][0];
}
for (int i = 0; i< col; i++)//判斷列
{
if (board[0][i] == board[1][i] && board[2][i] == board[1][i] && board[0][i] != ' ')
return board[i][i];
}
if ((board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[0][0] != ' ') || (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[0][2] != ' '))
//判斷對角線
return board[1][1];
for (int i = 0; i< row; i++)
{
for (int j = 0; j< col; j++)
{
if (board[i][j] == ' ')
{
return 'C';
}
}
}
return 'Q';
}
