本文实例为大家分享了C语言实现简单五子棋小游戏的具体代码，供大家参考，具体内容如下

在vs2019创建新项目，然后添加两个源文件test.c和game.c，接着创建一个头文件game.h。

test.c:

#include "game.h"
 
void game()
{
 char board[ROW][COL];
 InitBoard(board, ROW, COL);
 DisplayBoard(board, ROW, COL);
 char ret = 0;
 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("玩家赢\n");
 }
 else if (ret == '#')
 {
  printf("电脑赢\n");
 }
 else
 {
  printf("平局\n");
 }
}
 
void menu()
{
 printf("******************************\n");
 printf("*******     1.play      ******\n");
 printf("*******     0.exit      ******\n");
 printf("******************************\n");
}
int main()
{
 int input = 0;
 srand((unsigned int)time(NULL));
 do
 {
  menu();
  printf("请输入：\n");
  scanf("%d", &input);
  switch (input)
  {
  case 1:
   game();
   break;
  case 0:
   printf("退出游戏\n");
   break;
  default:
   printf("输入错误，请重新输入：\n");
   break;
  }
 } while (input);
 return 0;
}

game.c:

#include "game.h"
 
 
void InitBoard(char board[ROW][COL], int row, int col)
{
 int i = 0;
 for (i = 0; i < row; i++)
 {
  int j = 0;
  for (j = 0; j < col; j++)
  {
   board[i][j] = ' ';
  }
 }
}
 
void DisplayBoard(char board[ROW][COL], int row, int col)
{
 int i = 0;
 for (i = 0; i < row; i++)
 {
  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)
{
 printf("玩家走：\n");
 int i = 0;
 int j = 0;
 while (1)
 {
  printf("请输入坐标：\n");
  scanf("%d%d", &i, &j);
  if (i >= 1 && i <= row && j >= 1 && j <= col)
  {
   if (board[i - 1][j - 1] == ' ')
   {
    board[i - 1][j - 1] = '*';
    break;
   }
   else
   {
    printf("坐标被占用,请重新输入\n");
   }
  }
  else
  {
   printf("坐标超出范围\n");
  }
 }
}
 
 
void ComputerMove(char board[ROW][COL], int row, int col)
{
 int i = 0;
 int j = 0;
 printf("电脑走：\n");
 while (1)
 {
  i = rand() % row;
  j = rand() % col;
  if (board[i][j] == ' ')
  {
   board[i][j] = '#';
   break;
  }
 }
}
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;//棋盘没满
   }
  }
 }
 
 return 1;//棋盘满了
 
}
 
char IsWin(char board[ROW][COL], int row, int col)
{
 int i = 0;
 //判断三行
 for (i = 0; i < row; i++)
 {
  if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
  {
   return  board[i][1];//
  }
 }
 
 //判断三列
 for (i = 0; i < col; i++)
 {
  if (board[0][i] == board[1][i] && board[1][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[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];
 }
 
 //判断平局
 //如果棋盘满了返回1， 不满返回0
 int ret = IsFull(board, row, col);
 if (ret == 1)
 {
  return 'Q';
 }
 
 //继续
 return 'C';
}

game.h:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
 
#define ROW 3
#define COL 3
 
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 IsWin(char board[ROW][COL], int row, int col);
int IsFull(char board[ROW][COL], int row, int col);

运行效果如图：
