//初始化棋盤
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));
}
//打印棋盤
void print(char board[max_row][max_col]) {
 system("cls");//每次打印之前清除掉上一次的結(jié)果.
 for (int a = 0; a < max_col; a++) {
  printf("+---+---+---+\n");
  for (int b = 0; b < max_row; b++) {
   printf("| %c ", board[a][b]);
  }
  printf("| \n");
 }
 printf("+---+---+---+\n");
}

2.進行玩家落子,同樣是使用數(shù)組操作,讓玩家輸入相對應(yīng)的坐標,在二維數(shù)組的該位置打印'x'來表示玩家下的棋子

void play(char board[max_row][max_col]) {
 printf("玩家落子階段!\n");
 int a;
 int b;
 while (1) {
  printf("請輸入想要落子的坐標: ");
  scanf("%d %d", &a, &b);
  //判定玩家落子坐標是否在有效范圍內(nèi)
  if (a < 0 || b < 0 || a >= max_row || b >= max_col) {   
   printf("輸入坐標有誤請重新輸入!\n");                 
   continue;
  }
  //判定落子處是否已經(jīng)存在了棋子
  if (board[b][a] != ' ') {                                
   printf("此處已被落子無法再落子,請重新輸入!\n");
   continue;
  }
  board[b][a] = 'x';       //用'x'表示玩家落子
  break;
 }
}

3.玩家落子結(jié)束后讓電腦在二維數(shù)組中隨機落子,使用rand函數(shù)產(chǎn)生0到2的隨機數(shù)進行賦值操作,進而實現(xiàn)電腦隨機落子

void computer(char board[max_row][max_col]) {
 printf("電腦落子階段!\n");
 while (1) {
  int a = rand() % max_row; //產(chǎn)生0到2的隨機數(shù)
  int b = rand() % max_col;
  if (board[a][b] != ' ') { //判斷所下位置是否已經(jīng)有子
   continue;
  }
  board[a][b] = 'o';
  break;
 }

4.判斷勝負,當玩家落子結(jié)束,或者電腦落子結(jié)束后,判斷是否存在某行或某列或者對角線有相同的元素,如果有則直接判定結(jié)果,如果沒有則輪到下家落子

char check(char board[max_row][max_col]) {
 //檢測所有行是否相等
 for (int cow = 0; cow < max_row; cow++) {
  if (board[cow][0] != ' ' && board[cow][0] == board[cow][1] && board[cow][0]==board[cow][2] ) {
   return board[cow][0];
  }
 }
 //檢測所有列是否相等
 for (int 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];
  }
 }
 //檢測對角線是否相等
 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 (pingju(board)) {
  return 'q';   //棋子已滿和棋
 }
 return 'a';       //棋盤未滿
}
//判斷棋盤是否棋子已滿,如果滿了返回1,未滿返回0.
int pingju(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;
}

5.在主函數(shù)中調(diào)用以上函數(shù),進行操作:

int main() {
 char board[max_row][max_col] = {0};//數(shù)組初始化為0
 char winner = 'n';
 init(board); //將棋盤中元素初始化為空格
 while (1) {
  print(board);  //打印棋盤
  play(board);   //玩家落子
  winner = check(board);  //判斷勝負
  if (winner != 'a') {   
   break;
  }
  computer(board);      //電腦落子
  winner = check(board);  //判斷勝負
  if (winner != 'a') {
   break;
  }
 }
 
  if (winner == 'x') {
   print(board);
   printf("你贏了!");
  }
  else if (winner == 'o') {
   print(board);
   printf("你輸了!");
  }
  else if (winner == 'q') {
   print(board);
   printf("和棋!");
  }
 return 0;

在主函數(shù)中利用while循環(huán)來實現(xiàn)玩家與電腦的輪流落子,如果當一方落子之后勝負已出,則跳出循環(huán)直接打印最終結(jié)果.

完整代碼如下:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <windows.h>
#define max_row 3
#define max_col 3
//初始化棋盤
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));
}
//打印棋盤
void print(char board[max_row][max_col]) {
 system("cls");//每次打印之前清除掉上一次的結(jié)果.
 for (int a = 0; a < max_col; a++) {
  printf("+---+---+---+\n");
  for (int b = 0; b < max_row; b++) {
   printf("| %c ", board[a][b]);
  }
  printf("| \n");
 }
 printf("+---+---+---+\n");
}
 
//玩家落子
void play(char board[max_row][max_col]) {
 printf("玩家落子階段!\n");
 int a;
 int b;
 while (1) {
  printf("請輸入想要落子的坐標: ");
  scanf("%d %d", &a, &b);
  //判定玩家落子坐標是否在有效范圍內(nèi)
  if (a < 0 || b < 0 || a >= max_row || b >= max_col) {   
   printf("輸入坐標有誤請重新輸入!\n");                 
   continue;
  }
  //判定落子處是否已經(jīng)存在了棋子
  if (board[a][b] != ' ') {                                
   printf("此處已被落子無法再落子,請重新輸入!\n");
   continue;
  }
  board[a][b] = 'x';       //用'x'表示玩家落子
  break;
 }
}
//
void computer(char board[max_row][max_col]) {
 printf("電腦落子階段!\n");
 while (1) {
  int a = rand() % max_row; //產(chǎn)生0到2的隨機數(shù)

   return board[cow][0];
  }
 }
 //檢測所有列是否相等
 for (int 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];
  }
 }
 //檢測對角線是否相等
 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 (pingju(board)) {
  return 'q';
 }
 return 'a';
}
//判斷棋盤是否棋子已滿,如果滿了返回1,未滿返回0.
int pingju(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;
}
 
int main() {

  play(board);   //玩家落子
  winner = check(board);  //判斷勝負

   break;
  }

  if (winner != 'a') {
   break;
  }
 }
 
  if (winner == 'x') {

  }
 return 0;
}
