用c语言写一个贪吃蛇游戏

" 贪吃蛇游戏的基本要素包括蛇、食物和游戏界面。首先，需要声明一个蛇的结构体数组以及蛇的初始化函数。接着，需要声明一个食物的结构体变量以及生成食物的位置。然后，需要实现蛇的移动、食物的生成以及检测蛇是否撞到自己或界面的函数。最后，需要实现游戏的循环，包括画界面、接收用户输入以及更新蛇的位置和状态。
以下是一个简化版的贪吃蛇游戏实现：
```c
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <conio.h>
#define ROW 20
#define COL 20
typedef struct {
int x;
int y;
} Point;
typedef struct {
Point points[ROW * COL];
int len;
int head_x;
int head_y;
} Snake;
typedef struct {
Point p;
} Food;
void init_snake(Snake *s);
void generate_food(Snake *s, Food *f);
int move_snake(Snake *s, Food *f);
void draw_snake(Snake *s);
void draw_food(Food *f);
int main() {
Snake snake;
Food food;
init_snake(&snake);
generate_food(&snake, &food);
while (1) {
system("cls");
draw_snake(&snake);
draw_food(&food);
if (_kbhit()) {
switch (_getch()) {
case 'w':
if (move_snake(&snake, &food)) {
generate_food(&snake, &food);
}
break;
case 'a':
if (move_snake(&snake, &food)) {
generate_food(&snake, &food);
}
break;
case 's':
if (move_snake(&snake, &food)) {
generate_food(&snake, &food);
}
break;
case 'd':
if (move_snake(&snake, &food)) {
generate_food(&snake, &food);
}
break;
}
}
if (!move_snake(&snake, &food)) {
break;
}
Sleep(100);
}
printf("Game Over!\n");
return 0;
}
void init_snake(Snake *s) {
s->len = 3;
s->head_x = ROW / 2;
s->head_y = COL / 2;
for (int i = 0; i < s->len; i++) {
s->points[i].x = s->head_x;
s->points[i].y = s->head_y;
s->head_x = (s->head_x - 1 + ROW) % ROW;
s->head_y = (s->head_y - 1 + COL) % COL;
}
}
void generate_food(Snake *s, Food *f) {
f->p.x = rand() % ROW;
f->p.y = rand() % COL;
while (check_collision(s, f)) {
f->p.x = rand() % ROW;
f->p.y = rand() % COL;
}
}
int check_collision(Snake *s, Food *f) {
for (int i = 0; i < s->len; i++) {
if (s->points[i].x == f->p.x && s->points[i].y == f->p.y) {
return 1;
}
}
return 0;
}
int move_snake(Snake *s, Food *f) {
Point new_head = {f->p.x, f->p.y};
for (int i = s->len - 1; i > 0; i"
