给这段代码加一个每次出现食物都有可能多出现一个的功能 void drawfood() { setlinecolor(BLACK); //矩形边框黑色 setfillcolor(RED); fillrectangle(food.fdxy.x, food.fdxy.y, food.fdxy.x + 10, food.fdxy.y + 10); }

好的，可以通过引入随机数函数来实现每次出现食物时可能多出现一个的功能。具体实现方法如下：

void drawfood() {
setlinecolor(BLACK); //矩形边框黑色
setfillcolor(RED);
fillrectangle(food.fdxy.x, food.fdxy.y, food.fdxy.x + 10, food.fdxy.y + 10);

// 生成随机数，如果满足条件，则再生成一个食物
int rand_num = rand() % 10; // 生成0~9之间的随机数
if (rand_num == 0) { // 有1/10的概率生成一个额外的食物
int x = rand() % (WIDTH - 10); // 生成食物的横坐标
int y = rand() % (HEIGHT - 10); // 生成食物的纵坐标
setlinecolor(BLACK);
setfillcolor(RED);
fillrectangle(x, y, x + 10, y + 10);
}
}

这样每次出现食物时，都有1/10的概率再生成一个额外的食物。
