使用C++语言写贪吃蛇游戏代码，W，S，A，D控制上下左右移动

好的，这是一个关于编程的问题，可以回答。以下是使用 C 语言编写贪吃蛇游戏代码的代码示例，W，S，A，D 控制上下左右移动：

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
#include<time.h>
enum boolean { false,true };
enum direction { stop, up, down, left, right };
char map[25][25];
int pos_x[625], pos_y[625];
int snake_length = 3;
int direction_of_snake = stop;
bool is_gameover = false;
int score = 0;
void print_map() {
    int i,j;
    for (i = 0; i < 25; i++) {
        for (j = 0; j < 25; j++)
            printf("%c",map[j][i]);
        printf("\n");
    }
}
void init_map() {
    int i, j;
    for(i=0;i<25;i++)
        for (j = 0; j < 25; j++) {
            if (i == 0 || i == 24 || j == 0 || j == 24)
                map[i][j] = '#';
            else
                map[i][j] = ' ';
        }
    for (i = 1; i <= snake_length; i++) {
        pos_x[i] = 12;
        pos_y[i] = 12 + i - 1;
        map[pos_x[i]][pos_y[i]] = '*';
    }
    srand((unsigned)time(NULL));
    do {
        i = rand() % 22 + 1;
        j = rand() % 22 + 1;
    } while (map[i][j] != ' ');
    map[i][j] = '@';
}
void update_direction_of_snake() {
    int ch;
    if (_kbhit()) {
        ch = _getch();
        if (ch == -32)
            ch = _getch();
        if (ch == 119 && direction_of_snake != down)
            direction_of_snake = up;
        else if (ch == 115 && direction_of_snake != up)
            direction_of_snake = down;
        else if (ch == 97 && direction_of_snake != right)
            direction_of_snake = left;
        else if (ch == 100 && direction_of_snake != left)
            direction_of_snake = right;
    }
}
void update_snake() {
    int i;
    for (i = snake_length; i > 1; i--) {
        pos_x[i] = pos_x[i - 1];
        pos_y[i] = pos_y[i - 1];
    }
    if (direction_of_snake == up)
        pos_y[1]--;
    else if (direction_of_snake == down)
        pos_y[1]++;
    else if (direction_of_snake == left)
        pos_x[1]--;
    else if (direction_of_snake == right)
        pos_x[1]++;
    if (map[pos_x[1]][pos_y[1]] == '#' || map[pos_x[1]][pos_y[1]] == '*')
        is_gameover = true;
    if (map[pos_x[1]][pos_y[1]] == '@') {
        snake_length++;
        score++;
        do {
            i = rand() % 22 + 1;
            j = rand() % 22 + 1;
        } while (map[i][j] != ' ');
        map[i][j] = '@';
    }
    for (i = 1; i <= snake_length; i++)
        map[pos_x[i]][pos_y[i]] = '*';
    map[pos_x[snake_length + 1]][pos_y[snake_length + 1]] = ' ';
}
int main()
{
    init_map();
    while (!is_gameover) {
        print_map();
        update_direction_of_snake();
        update_snake();
        Sleep(200);
        system("cls");
    }
    printf("Game Over!\nYour score is %d.", score);
    return 0;
}

请注意，这只是一份示例代码，您可能需要对其进行修改或添加代码以满足您的具体要求。
