C++ 类和构造函数有很多错误和问题

下面是文件“lib.h”的代码

下面是文件“Makefile”的代码

这个程序应该以如下方式工作：我们有一个“Bird”类元素的动态数组，它有一个元素的4个特征，还有一个结构“BirdHome”，它包含当前元素的4个特征。运行此程序时，您将使用带参数的构造函数自动初始化数组中的三个元素（我还有一个默认contsructor和一个复制contsructor，但现在不需要它们）。然后它会打印所有元素，然后显示一个具有特定索引的元素，然后删除一个具有特定索引的元素。然后会显示此数组的内容。但我有13个错误，我真的不知道如何修复它们。我只是试图重写某人的代码，但使用了我的元素，但出现了以下错误：

你能帮我解决它们吗？

这里的问题是，原始数组中肯定包含了类“Bird”的动态数组，但它没有。因为是这样的

Bird** arr

通过将其更改为代码中的正常使用方式，就像下面这样

Bird** birds

---

程序开始正常工作

第一个错误是由于缺少括号：

BirdHome:：BirdHome{

-->

BirdHome:：BirdHome（）{

和

Array

没有名为

birds

的成员。哇，你真的帮了我的忙。我忘了我做了

Bird**arr

而不是

Bird**birds

我的建议是从顶部开始读取错误。很多时候，一个问题可能会触发多个错误。

void removeBird（int index）const；

如果

removeBird（）

要对对象进行更改，则需要在末尾删除

const

。

包含“lib.cpp”

从不包含.cpp文件。..h文件适合包含。
