The pure C language realizes the greedy snake game (VC6.0)

Transfer from C language network

Today I show you the C language to write the greedy snake game, let everyone play a game of their own write ~ is pure C language Oh ~vc6.0 development No problem

First, start the interface:

The game interface is as follows:

The code is as follows:

The author VC6.0, Test no problem, can copy the code directly to the VC6 source file, the suffix is. c file can be compiled by running ~

#include <stdio.h>
#include <time.h>
#include <windows.h>
#include <stdlib.h>
#define U 1
#define D 2
#define L 3
#define R 4//Snake State, U: up; D: down; L: Left R: Right
typedef struct SNAKE//A node of a snake body
{
int x;
int y;
struct SNAKE *next;
}snake;
Global variable//
int score=0,add=10;//total score with each eating food score.
int status,sleeptime=200;//The time interval of each run
Snake *head, *food;//snake head pointer, food pointer
Snake *q;//The use of the pointer when traversing the snake
int endgamestatus=0; The end of the game, 1: Hit the wall, 2: Biting himself; 3: actively quit the game.
