In C, derived classes can inherit from one base class only.
It also defines those methods that the derived class must implement on its own.
它还定义派生类必须自行实现的那些方法。A derived class can access all the non-private members of its base class. .
派生类可以访问它的基类的所有非私有成员。ClassC:publicB{//注意C继承自B而不是A.The derived class can access all the non-private members of its base class. .
派生类可以访问基类中所有的非私有成员。You have two ways to differentiate your new derived class from the original base class. .
有两种方法能使新派生类区别于原始基类。Derived class can access the public and protected members of the base class. .
派生类可以访问基类的public和protected成员。You have two ways to differentiate your new derived class from the original base class. .
有两种做法可将新得的衍生类与原来的基础类区分开。Derived class can access the public and protected members of the base class. .
L派生类可以访问基类的public和protected的成员。When a pointer to a protected member is formed,it must use a derived class in its declaration:.
组成指向受保护成员的指针时，必须在其声明中使用派生类：.In principle, a derived class inherits every member of a base class except:.
理论上说，子类(drivedclass)继承了基类(baseclass)的所有成员，除了：.类类型支持继承，继承是一种机制，它使派生类可以对基类进行扩展和专用化。Thus, a derived class or interface is allowed to declare a member with the same name as an inherited member.
这样，一个派生的类或接口可以用和继承的成员相同的名称声明一个成员。Multi-level inheritance- from base class base1, a derived class d1 is inherited and from base2, d2 is inherited.
Multi-level继承-从基类base1继承的派生类d1，d2继承自base2。A derived class can add new members to those it inherits, but it cannot remove the definition of an inherited member.
派生类可以添加新的成员，但不能除去已经继承的成员的定义。The following code example uses the derived class Text Box and validates an e-mail address that the user enters.
示例下面的代码示例使用派生类TextBox并验证用户输入的电子邮件地址。A derived class can add new members to those it inherits, but it cannot remove the definition of an inherited member.
派生类能够在继承基类的基础上添加新的成员，但是它不能移除继承成员的定义。The implementation in each Element derived class is always the same- accept( Visitor v){ v. visit( this);}.
Derived classes must be useful through the base class interface, without the need for the user to know the difference.
派生类必须能通过基类的接口而被使用，且使用者无须了解两者之间的差异。A Mammalis an Animal, and a Reptile is an Animal, but each derived class represents different specializations of the base class.“.
Mammal是一个Animal，Reptile也是一个Animal，但每个派生类均表示基类的不同专用化。Dog is a derived class that derives from the Animal base class using the extends keyword.
Dog是一个派生类，它派生自Animal基类，通过extends关键字。Next, the static initialization in the root base class(in this case, Insect) is performed,and then the next derived class, and so on.
接下来，根基类中的静态初始化（在此例中为Insect）即会被执行，然后是下一个导出类，以此类推。Also, overridden methods in a derived class cannot reduce the access of the method in the base class. .
此外，在衍生类中的优先方法不能减少对基础类方法的访问。If you simply inherit a class and don't do anything else,the methods from the base-class interface come right along into the derived class.
若只是简单地继承一个类，并不做其他任何事情，来自基础类接口的方法就会直接照搬到衍生类。Inheritance in which a derived class is derived from several base class is known as multiple inheritance.
从多个基类中派生的继承方式称为多继承。If you simply inherit a class and don't do anything else,the methods from the base-class interface come right along into the derived class.
如果只是简单地继承一个类而并不做其他任何事，那么在基类接口中的方法将会直接继承到导出类中。Without explicitly re-implementing an interface, a derived class cannot in any way alter the interface mappings it inherits from its base classes. .
不通过显式的实现一个接口，一个派生类不能用任何方法改变它从它的基本类继承的接口映射。Protected Inheritance: When deriving from a protected base class, public andprotected members of the base class become protected members of the derived class.
保护继承（protecte）：当一个类派生自保护基类时，基类的公有和保护成员将成为派生类的保护成员.Everything that applies to base classes must also apply to derived classes, because every derived class object is a base class object.
适用于baseclasses身上的每一件事一定也适用于derivedclasses身上，因为每一个derivedclasses对象也都是一个baseclass对象。
