這篇文章主要為大家詳細介紹了70行C語言代碼實現貪吃蛇，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了C語言實現貪吃蛇的具體代碼，供大家參考，具體內容如下

#include <stdio.h> 
#include <Windows.h> 
#include <conio.h> 
#include <time.h> 
 
#define MAX_WIDE 50 
#define MAX_HIGH 16 
 
short dx = 1, dy = 0, randxy, score = 0; 
COORD coord; 
 
struct Snake{ 
 short len; 
 short body[MAX_WIDE*MAX_HIGH]; 
}snake; 
 
void draw() 
{ 
 for(short i = 0; i < snake.len; i++){ 
  coord.X = snake.body[i] & 127; 
  coord.Y = snake.body[i] >> 8; 
  SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord); 
  putchar('*'); 
 } 
 coord.X = randxy & 127; 
 coord.Y = randxy >> 8; 
 SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord); 
 putchar('*'); 
} 
void run() 
{ 
 char key; 
 short i, j; 
 while( snake.body[0] > 0 && ( (snake.body[0] & 127) < MAX_WIDE) && (snake.body[0]>>8 < MAX_HIGH) ){ 
  draw(); 
  for(;kbhit();) key = getch(); 
  switch(key){ 
  case 'W': dx = 0, dy = -1; break; 
  case 'S': dx = 0, dy = 1; break; 
  case 'A': dx = -1, dy = 0; break; 
  case 'D': dx = 1, dy = 0; break; 
  } 
  for(j = 1; j < snake.len; j++) 
   if(snake.body[j] == snake.body[0]) 
    return; 
  if(randxy == snake.body[0]){ 
    snake.len++, score += 10; 
    randxy = ((rand() % 16 + 0) <<8) | (rand() % 50 + 0); 
  } 
  for(i = snake.len-1; i > 0; i--) 
   snake.body[i] = snake.body[i-1]; 
  snake.body[0] = ((snake.body[0] & 127) + dx) | ((snake.body[0] >>8) + dy)<<8; 
  Sleep(500); 
  system("cls"); 
 } 
} 
int main() 
{

 snake.body[0] = (MAX_HIGH/2)<<8 | MAX_WIDE/2; 
 snake.len = 1; 
 srand((unsigned)time(NULL)); 
 randxy = ((rand() % 16 + 0) <<8) | (rand() % 50 + 0); 
 SMALL_RECT rect; 
 rect.Top = 0, rect.Left = 0; 
 rect.Bottom = MAX_HIGH, rect.Right = MAX_WIDE; 
 SetConsoleWindowInfo(GetStdHandle(STD_OUTPUT_HANDLE), true, &rect); 
 run(); 
 printf("Your Score:%d", score); 
 return 0; 
}
