智能贪吃蛇

所谓智能蛇，就是自己动起来吃食物的蛇，下面给出代码的函数头：

#include <stdio.h>#include <stdlib.h>#include <time.h>#include <math.h>#define SNAKE_MAX_LENGTH 20#define SNAKE_HEAD 'H'#define SNAKE_BODY 'X'#define SNAKE_FOOD '$'#define WALL_CELL '*'#define MAP_LENGTH 12int snakeLength = 5;int snakeX[SNAKE_MAX_LENGTH] = {1,2,3,4,5};//record the x-axis every part of the                                                   body at the beginningint snakeY[SNAKE_MAX_LENGTH] = {1,1,1,1,1};//record the y-axis every part of the                                             body at the beginningchar map[15][15] = //initial the map{    "************",    "*XXXXH     *",    "*          *",    "*          *",    "*          *",    "*          *",    "*          *",    "*          *",    "*          *",    "*          *",    "*          *",    "************"};void Creat_Food();void Print();//when eating food or moving print the map once void Clear();//when the food is eaten clear itvoid Draw();//change the snakeint eatfood(int x, int y);//check whether the next step can eat the foodint is_ok(int x,int y);//check whether the next step can be executedvoid snakeMove(int x,int y);//next step have several selecions, analyse themint headi,headj,foodi,foodj;//record the location of the head of the snake and                             food;void find_head();//find where the head of the snake isvoid find_food();//find wher the food isint movable[4];//check which direction is availablevoid find_way();//find how to move next step int distance[4];//store four distancesvoid count_distance();void SmartSnake();

蛇移动 snakeMove

void snakeMove(int x,int y){    if(!is_ok(x,y))    {        getchar();        printf("Sorry,GAME OVER! PUSH \"C\" TO CONTINUE\n");        getchar();        return ;    }    if(eatfood(x,y))    {        Creat_Food();    }    int i;    for(i = 0; i < snakeLength-1; i++)    {        snakeX[i] = snakeX[i+1];        snakeY[i] = snakeY[i+1];    }    snakeX[snakeLength-1] += x;    snakeY[snakeLength-1] += y;    Clear();    Draw();}

是否可行 is_ok

int is_ok(int x,int y){    int headX = snakeX[snakeLength-1]+x;    int headY = snakeY[snakeLength-1]+y;    int i;    if(headX <= 0 || headX >= 11 || headY <= 0 || headY >= 11)        return 0;    if(map[headY][headX] == '*')        return 0;    for(i = 0; i < snakeLength; ++i)    {        int bodyX = snakeX[i];        int bodyY = snakeY[i];        if(headX == bodyX && headY == bodyY)            return 0;        }    return 1;}

吃食物eat_food

int eatfood(int x, int y){    int headX = snakeX[snakeLength-1]+x;    int headY = snakeY[snakeLength-1]+y;    if(map[headY][headX] == '$')    {        snakeLength++;        snakeX[snakeLength-1] = headX;        snakeY[snakeLength-1] = headY;        return 1;    }return 0;}

实际上，多亏宿舍的大佬跟我讲思路并给我看了他的代码
