三子棋是黑白棋的一种。三子棋是一种民间传统游戏，又叫九宫棋、圈圈叉叉、一条龙、井字棋等。将正方形对角线连起来，相对两边依次摆上三个双方棋子，只要将自己的三个棋子走成一条线，对方就算输了。但是，有很多时候会出现和棋的情况。
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <windows.h>
#define MAX_ROW 3
#define MAX_COL 3
利用宏定义来定义棋盘的大小，因为井字棋需要一个3*3的棋盘，为了避免魔幻数字（在后续代码中出现，不能很直观的看出是长还是宽）的出现，我们用ROW和COl来代替
void init(char board[MAX_ROW][MAX_COL]) {
for (int row = 0; row < MAX_ROW; row++) {
for (int col = 0; col < MAX_COL; col++) {
board[row][col] = ' ';
}
}
srand((unsigned int)time(0));
}
//给用户打印一个棋盘
void printBoard(char board[MAX_ROW][MAX_COL]) {
system("cls");
for (int row = 0; row < MAX_ROW; row++) {
printf("+--+--+--+\n");
for (int col = 0; col < MAX_COL; col++) {
printf("| %c", board[row][col]);
}
printf("|");
printf("\n");
}
printf("+--+--+--+\n");
}
//玩家落子函数
void playerMove(char board[MAX_ROW][MAX_COL]) {
while (1) {
printf("请玩家落子!");
printf("请输入你要落子的位置(row col):");
int row = 0;
int col = 0;
scanf("%d %d", &row, &col);
if (row < 0 || row > MAX_ROW || col < 0 || col > MAX_COL) {
printf("你的输入有误,请重新输入!\n");
continue;
}
if (board[row][col] != ' ') {
printf("你输入的位置已经有子,无法继续落子!\n");
continue;
}
board[row][col] = 'x';
break;
}
}
//电脑落子函数
void computerMove(char board[MAX_ROW][MAX_COL]) {
printf("轮到电脑落子!\n");
while (1) {
int row = rand() % MAX_ROW;
int col = rand() % MAX_COL;
if (board[row][col] == 'x') {
continue;
}
board[row][col] = 'o';
break;
}
}
//判断是否和棋
int isFull(char board[MAX_ROW][MAX_COL]) {
for (int row = 0; row < MAX_ROW; row++) {
for (int col = 0; col < MAX_COL; col++) {
if (board[row][col] == ' ')
return 0;
}
}
return 1;
}
//判断是否连成一条线
char checkWinner(char board[MAX_ROW][MAX_COL]) {
int row = 0;
int col = 0;
for (row = 0; row < MAX_ROW; row++) {
if (board[row][col] != ' ' && board[row][0] == board[row][1] && board[row][0] == board[row][2]) {
return board[row][0];
}
}
for (col = 0; col < MAX_COL; col++) {
if (board[0][col] != ' ' && board[0][col] == board[1][col] && board[0][col] == board[2][col]) {
return board[0][col];
}
}
if (board[0][0] != ' ' && board[0][0] == board[1][1] && board[0][0] == board[2][2]) {
return board[0][0];
}
if (board[0][2] != ' ' && board[0][2] == board[1][1] && board[0][2] == board[2][0]) {
return board[0][2];
}
if (isFull(board)) {
//棋盘满返回一个q
return 'q';
}
//棋盘没满返回一个空字符
return ' ';
}
int main() {
char board[MAX_ROW][MAX_COL] = { 0 };
char winner = ' ';
init(board);
while (1) {
printBoard(board);
//system("pause");
playerMove(board);
checkWinner(board);
winner = checkWinner(board);
if (winner != ' ') {
printBoard(board);
break;
}
computerMove(board);
winner = checkWinner(board);
if (winner != ' ') {
break;
}
}
if (winner == 'x') {
printf("恭喜你,你赢了!!!");
}
else if (winner == 'o') {
printf("你真菜,竟然输了");
}
else {
printf("你和人工智障五五开");
}
return 0;
}
以上就是三子棋的全部内容,欢迎大家提出问题.
