贪吃蛇c++语言代码

以下是一个简单的 C++ 代码示例，实现了一个控制台版的贪吃蛇游戏：

#include <iostream>
#include <conio.h>
#include <windows.h>

bool gameOver;
const int width = 20;
const int height = 20;
int x, y, fruitX, fruitY, score;
int tailX[100], tailY[100];
int nTail;
enum eDirection { STOP = 0, LEFT, RIGHT, UP, DOWN };
eDirection dir;

void Setup()
{
    gameOver = false;
    dir = STOP;
    x = width / 2;
    y = height / 2;
    fruitX = rand() % width;
    fruitY = rand() % height;
    score = 0;
}

void Draw()
{
    system("cls");

    for (int i = 0; i < width + 2; i++)
        std::cout << "#";
    std::cout << std::endl;

    for (int i = 0; i < height; i++)
    {
        for (int j = 0; j < width; j++)
        {
            if (j == 0)
                std::cout << "#";
            if (i == y && j == x)
                std::cout << "O";
            else if (i == fruitY && j == fruitX)
                std::cout << "F";
            else
            {
                bool printTail = false;
                for (int k = 0; k < nTail; k++)
                {
                    if (tailX[k] == j && tailY[k] == i)
                    {
                        std::cout << "o";
                        printTail = true;
                    }
                }
                if (!printTail)
                    std::cout << " ";
            }
            if (j == width - 1)
                std::cout << "#";
        }
        std::cout << std::endl;
    }

    for (int i = 0; i < width + 2; i++)
        std::cout << "#";
    std::cout << std::endl;
    std::cout <<
