求解啊！！！新手不明白，总是报错，如图所示。

/*
定义一个基类，哺乳动物类Mammal，其中数据成员有年龄、重量、品种，成员函数有move（）、speak（）等，以此表示动物的行为。
由这个基类派生出狗、猫、马、猪四种哺乳动物，它们有各自的行为。编程实现使各个动物分别表现出不同的行为。 具体要求如下：
1、从基类分别派生出各种动物类，通过虚函数实现不同动物表现出的不同行为。
2、现有动物：狗： CAIRN：3岁，3kg； DORE：4岁，2kg；
猫： CAT：5 岁，4kg； 马：HORSE，5岁，60kg；
猪： PIG，2岁，45kg。
3、对应的动作中要先显示出动物的名称，然后显示年龄、重量、品种、叫声及其他特征。
4、设置一个 Mammal 类数组，设计一个屏幕菜单，选择不同的动物或不同的品种，则显示出动物相对应的动作，直到选择结束。

你所有派生类的初始化参数列表都有问题。
显式父类初始化的时候:Mammal(name, age, weight)应该改为:Mammal(n, a, w)
