【C/C++小游戏】控制台飞机大战

• 谁说控制台只能用来刷题？
• 谁说做游戏只能用第三方库？
• 控制台当然能用来做游戏！ 

只需要三个头文件（指 devc++），那就是：

bits/stdc++.h        万能头文件，不用说了

conio.h                 专门检测键盘按键

windows.h            这是最重要的一个，能对控制台最很多风骚操作！

代码放在最后面，来看看有哪些特殊操作！

1  gotoxy 函数：

这是一个常用的函数，虽然要自己写。它的作用是用来移动光标到特定的位置，输出的内容会覆盖原来的内容。

2  setsize 函数：

用 system 命令实现在 cmd 中输入指令，调整窗口大小。

3  color 函数

改变输出文字的颜色（前景、背景）。

数字对应的颜色，参考文章：C++ 设置控制台字体主题，颜色和背景颜色_爱学习的蓝调的博客-优快云博客_setconsolecolor

4  HideCursor 函数：

把光标隐藏了，要不然那玩意儿闪来闪去，看得难受。 

好了，就这些函数，直接抄！

其余的代码就是飞机大战的算法，没什么难度。
