devc++编写c语言贪吃蛇

在DevC++中编写C语言贪吃蛇的示例代码如下：

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

#define WIDTH 20
#define HEIGHT 20

int score;
int gameover;
int x, y, fruitX, fruitY, flag;

int tailX[100], tailY[100];
int nTail;

void Setup()
{
    gameover = 0;
    x = WIDTH / 2;
    y = HEIGHT / 2;

    fruitX = rand() % WIDTH;
    fruitY = rand() % HEIGHT;
    score = 0;
}

void Draw()
{
    int i, j, k;
    system("cls");

    for (i = 0; i < WIDTH + 2; i++)
        printf("#");
    printf("\n");

    for (i = 0; i < HEIGHT; i++)
    {

        {
            if (j == 0)
                printf("#");

            if (i == y && j == x)
                printf("O");
            else if (i == fruitY && j == fruitX)
