用c语言写一个贪吃蛇

好的，这是一个用C语言写的简单的贪吃蛇游戏代码：

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

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

void gotoxy(int x, int y)
{
    COORD coord;
    coord.X = x;
    coord.Y = y;
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}

int main()
{
    int x = 10, y = 10;
    int fruitx, fruity;
    int score = 0;
    int gameover;
    int flag;

    fruitx = rand() % 20 + 1;
    fruity = rand() % 20 + 1;

    while(1)
    {
        if (kbhit())
        {
            switch (getch())
            {
                case UP:
                    y--;
                    break;
                case DOWN:
                    y++;
                    break;
                case LEFT:
                    x--;
                    break;
                case RIGHT:
                    x++;
                    break;
            }
        }

        if (x == fruitx && y == fruity)
        {
            score += 10;
            fruitx = rand() % 20 + 1;
            fruity = rand() % 20 + 1;
        }

        gotoxy(0, 0);
        printf("Score: %d", score);
        gotoxy(x, y);
        printf("O");
        gotoxy(fruitx, fruity);
        printf("F");

        Sleep(100);
    }

    return 0;
}

希望这能帮到你！
