能用c语言编写一段贪吃蛇的代码吗

可以，以下是一份简单的C语言贪吃蛇代码：

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <windows.h>

#define MAP_WIDTH 20
#define MAP_HEIGHT 20

int snakeX[100], snakeY[100], snakeLen = 3; 
int foodX, foodY, score = 0;
int directionX = 1, directionY = 0;
int map[MAP_HEIGHT][MAP_WIDTH] = {0};

void drawMap(){
    system("cls"); 
    printf("Score: %d\n", score); 
    for(int i = 0; i <= MAP_HEIGHT; i++){
        for(int j = 0; j <= MAP_WIDTH; j++){
            if(map[i][j] == 1) printf("*");
            else if(i == 0 || j == 0 || i == MAP_HEIGHT || j == MAP_WIDTH) printf("#");
            else if(i == foodY && j == foodX) printf("$");
            else printf(" ");
        }
        printf("\n");
    }
}

void generateFood(){
    foodX = rand() % (MAP_WIDTH - 2) + 1;
    foodY = rand() % (MAP_HEIGHT - 2) + 1;
    if(map[foodY][foodX] == 1) generateFood(); 
}

int main(){
    snakeX[0] = 3;
    snakeY[0] = 1;
    map[snakeY[0]][snakeX[0]] = 1;
    generateFood(); 
    drawMap(); 

    while(1){
        Sleep(100); 
        if(kbhit()){ 
            char c = getch();
            if(c == 'w') directionX = 0, directionY = -1;
            else if(c == 'a') directionX = -1, directionY = 0;
            else if(c == 's') directionX = 0, directionY = 1;
            else if(c == 'd') directionX = 1, directionY = 0;
        }
        int nextX = snakeX[snakeLen-1] + directionX;
        int nextY = snakeY[snakeLen-1] + directionY;
        if(nextX == 0 || nextX == MAP_WIDTH || nextY == 0 || nextY == MAP_HEIGHT) break; 
        if(map[nextY][nextX] == 1) break; 
        if(nextX == foodX && nextY == foodY){ 
            map[nextY][nextX] = 1;
            snakeX[snakeLen] = nextX;
            snakeY[snakeLen] = nextY;
            snakeLen++; 
            score += 10; 
            generateFood(); 
        }else{ 
            map[snakeY[0]][snakeX[0]] = 0;
            for(int i = 0; i < snakeLen - 1; i++){
                snakeX[i] = snakeX[i + 1];
                snakeY[i] = snakeY[i + 1];
            }
            snakeX[snakeLen-1] = nextX;
            snakeY[snakeLen-1] = nextY;
            map[nextY][nextX] = 1;
        }
        drawMap();
    }
    printf("Game Over! Score: %d\n", score);
    return 0;
}
