c语言：来实现一个小程序n子棋（已五子棋为例）

首先是头文件的代码

#pragma once
#define ROW 5
#define COL 5
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
void start__board(char board[ROW][COL], int row, int col);
void start__qipan(char board[ROW][COL], int row, int col);
//void qipan__board(char board[ROW][COL], int row, int col);
void player__board(char board[ROW][COL],int row, int col);
void computer__board(char board[ROW][COL], int row, int col);
char  win(char board[ROW][COL], int row, int col);

然后是实现函数个个功能的代码

#include"game.h"
void start__board(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (int i = 0; i < row; i++)
	{
		for (int j = 0; j < col; j++)
		{
			board[i][j] = ' ';
		}
	}
}
void start__qipan(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (int i = 0; i < row; i++)
	{
		for (int j = 0; j < col; j++)
		{
			printf(" %c ", board[i][j]);
			if (j < col - 1)
				printf("|");
		}
		printf("\n");
		if (i < row - 1)
		{
			for (int j = 0; j < col; j++)
			{
				printf("---");
				if (j < col - 1)
					printf("|");
			}
		}
		printf("\n");
	}
}
//void qipan__board(char board[ROW][COL], int row, int col)
//{
//	int i = 0;
//		for (i = 0; i < row; i++)
//		{
//			for (int n = 0; n < col;n++)
//			{
//				
//			}
//		}
//}
void player__board(char board[ROW][COL], int row, int col)
{
	int x, y;
	printf("玩家下棋：\n");
	while (1)
	{
		printf("请输入坐标：->\n");
		scanf_s("%d %d", &x, &y);
		if (x > 0 && x < row+1&& y>0 && y < col+1)
		{
			if (board[x-1][y-1]==' ')
			{
				board[x-1][y-1] = '*';
				break;
			}
			else
				printf("非法占用，请重新输入：\n");
		}
		else
			printf("超出范围，请重新输入\n");
	}
	
}
void computer__board(char board[ROW][COL], int row, int col)
{
	printf("电脑下棋：\n");
	while (1)
	{
		int x = rand() % 6;
		int y = rand() % 6;
		if (x > 0 && x < row + 1 && y>0 && y < col + 1)
		{
			if (board[x][y] == ' ')
			{
				board[x][y] = '#';
				break;
			}
		}
	}
}
char win(char board[ROW][COL], int row, int col)
{
	char p='c';
	int i;
	int j;
	for (int i = 0; i < row; i++)
	{
			if (board[i][0] == board[i][1] && board[i][1] == board[i][2]&&board[i][2] == board[i][3]&&board[i][3] == board[i][4]&&board[i][0] == '*')
				p = '*';
			if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][2] == board[i][3] && board[i][3] == board[i][4] && board[i][0] == '#')
				p = '#';
			
	}
	for (int j = 0; j < col; j++)
	{
		if (board[0][j] == board[1][j] && board[1][j] == board[2][j] && board[2][j] == board[3][j] && board[3][j] == board[4][j] && board[j][4] == '*')
			p = '*';
		if (board[0][j] == board[1][j] && board[1][j] == board[2][j] && board[2][j] == board[3][j] && board[3][j] == board[4][j] && board[j][4] == '#')
			p = '#';

	}
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[2][2] == board[3][3] && board[3][3] == board[4][4] && board[0][0] == '*')
		p = '*';
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[2][2] == board[3][3] && board[3][3] == board[4][4] && board[0][0] == '#')
		p = '#';
	if (board[0][4] == board[1][3] && board[1][3] == board[2][2] && board[2][2] == board[3][1] && board[3][1] == board[4][0])
	{
		if (board[0][4] == '*')
			p = '*';
		if (board[0][4] == '#')
			p = '#';
	}
	int a = 0;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			if (board[i][j] != ' ')
				a = 1;
		}
	}
	if (a == 0)
		p = 'p';
	return p;
}

最后是主函数的代码啦

#include"game.h"
void menu()
{
	printf("***************************\n");
	printf("*********  1.play  ********\n");
	printf("*********  0.exit  ********\n");
	printf("***************************\n");
}
void game()
{
	int ret;
	printf("五子棋游戏开始\n");
	char board[ROW][COL] = {0};
	start__board(board, ROW, COL);
	start__qipan(board, ROW, COL);
	//qipan__board(board, ROW, COL);
	while (1)
	{
		player__board(board, ROW, COL);
		ret = win(board, ROW, COL);
		if (ret != 'c')
			break;
		start__qipan(board, ROW, COL);
		computer__board(board, ROW, COL);
		ret =win(board, ROW, COL);
		if (ret != 'c')
			break;
		start__qipan(board, ROW, COL);
	}
	if (ret == '*')
		printf("玩家获胜\n");
	if (ret == '#')
		printf("电脑获胜\n");
	if (ret == 'p')
		printf("平局\n");
}
int main()
{
	srand((unsigned int)time(NULL));
	int m;
	do
	{
		menu();
		printf("请选择:->\n");
		scanf_s("%d", & m);
		switch (m)
		{
		case 1:
			game();
			break;
		case 0:
			printf("退出游戏\n");
			break;
		default:
			printf("选择错误，请重新选择：\n");
			break;

		}
	} while (m);

	return 0;
}
