用C++写一个飞机大战的游戏

这是一个关于如何使用C语言编写飞机大战游戏的简单示例：

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

#define MAX_X 50
#define MAX_Y 20

void gotoxy(int x, int y)
{
    COORD coord;
    coord.X = x;
    coord.Y = y;
    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}

void hide_cursor()
{
    HANDLE consoleHandle = GetStdHandle(STD_OUTPUT_HANDLE);
    CONSOLE_CURSOR_INFO info;
    info.dwSize = 100;
    info.bVisible = FALSE;
    SetConsoleCursorInfo(consoleHandle, &info);
}

void clear_screen()
{
    system("cls");
}

void draw_boundary()
{
    int i;
    for (i = 0; i < MAX_X; i++)
    {
        gotoxy(i, 0);
        printf("-");
        gotoxy(i, MAX_Y);
        printf("-");
    }
    for (i = 0; i <= MAX_Y; i++)
    {
        gotoxy(0, i);
        printf("|");
        gotoxy(MAX_X, i);
        printf("|");
    }
}

void draw_plane(int x, int y)
{
    gotoxy(x, y);
    printf("^");
    gotoxy(x + 1, y + 1);
    printf("/ \\ ");
    gotoxy(x + 1, y + 2);
    printf("\\ /");
}

{
    int x = MAX_X / 2, y = MAX_Y - 1;

            {
                x++;
                clear_screen();
                draw_boundary();
                draw_plane(x, y);
            }
            break;
