用dev写个贪吃蛇代码、

好的，以下是使用Dev C++编写的贪吃蛇代码：

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <windows.h>

#define UP    72
#define DOWN  80
#define LEFT  75
#define RIGHT 77

int width = 30, height = 20;
int snake_x[100], snake_y[100];
int food_x, food_y, score;
int direction, gameover;

void draw()      // 绘制游戏界面
{
    system("cls");                // 清屏
    for (int i = 0; i <= width; i++)
        printf("#");               // 顶部边框
    printf("\n");
    for (int i = 1; i <= height; i++)
    {
        for (int j = 0; j <= width; j++)
        {
            if (j == 0 || j == width)
                printf("#");      // 左右边框
            else if (i == snake_y[0] && j == snake_x[0])
                printf("O");      // 蛇头
            else if (i == food_y && j == food_x)
                printf("*");      // 食物
            else
            {
                int flag = 0;
                for (int k = 1; k < score; k++)

                        flag = 1;
                    }
                }
                if (flag == 0)       // 空格
                    printf(" ");
            }
        }
        printf("\n");
    }
    for (int i = 0; i <= width; i++)
        printf("#");               // 底部边框
    printf("\n");
    printf("Score: %d\n", score);
}

void setup()     // 初始化
{
    snake_x[0] = width / 2;     // 蛇的初始位置
    snake_y[0] = height / 2;
    food_x = rand() % (width - 2) + 1;   // 食物的初始位置
    food_y = rand() % (height - 2) + 1;
    score = 0;                  // 得分

        switch (_getch())
        {
        case UP:
            if (direction != DOWN)
                direction = UP;
            break;
        case DOWN:

                direction = DOWN;

    }
    if (snake_x[0] == 0 || snake_x[0] == width || snake_y[0] == 0 || snake_y[0] == height)
        gameover = 1;           // 碰到边界，游戏结束
    for (int i = 1; i < score; i++)

            gameover = 1;       // 碰到自身，游戏结束
    }
    if (snake_x[0] == food_x && snake_y[0] == food_y)   // 吃到食物
    {
        score++;
        food_x = rand() % (width - 2) + 1;
        food_y = rand() % (height - 2) + 1;
    }
}

int main()
{
    setup();        // 初始化
    while (!gameover)
    {
        draw();     // 绘制游戏界面
        input();    // 接收方向键
        logic();    // 游戏逻辑
        Sleep(50);  // 延时，调整游戏速度
    }
    printf("Game Over!\n");

}

这是一个简单的控制台小游戏，用户通过方向键控制蛇的移动，吃到食物得分，碰到自身或者边界游戏结束。
