2. Like the subscript and dereference operators, assignment returns an lvalue.

与下标和解引用操作符一样，赋值操作也返回左值。

3. To do this, we simply have to precede the pointer's identifier with an asterisk (*), which acts as dereference operator and that can be literally translated to "value pointed by".

4. Code analysis tool detects common coding errors, such as buffer overrun, un-initialized memory, null pointer dereference, and memory and resource leaks.

代码分析工具用于检测常见的编码错误,例如缓冲区溢出、内存未初始化、空指针取消引用,以及内存和资源泄露。

5. The * symbol is used as the (unary) dereference operator and as the (binary) multiplication operator.The uses of the symbol are independent;it can be helpful to think of them as two different symbols.

例如，符号*既可以作为（一元）解引用操作符，也可以作为（二元）乘法操作符，这两种用法相互独立、各不相关，如果将其视为两个不同的符号可能会更容易理解些。

6. It is legal to compute an address one past the end of an array or object.It is not legal to dereference a pointer that holds such an address.

允许计算数组或对象的超出末端的地址，但不允许对此地址进行解引用操作。

7. Is there an archiver that dereference a symbolic link if the link would be broken, but not dereference, otherwise?

9. Also, the dereference operator, which allows reading and writing to a pointer.

另外还用作取消引用运算符,允许读取和写入指针。

10. A pointer to member may be bound to any member of the class that has the same type.When we dereference a pointer to member, an object from which to fetch the member must be specified.

可以将成员指针绑定到具有相同类型的任意类成员，引用成员指针的时候，必须指定从中获取成员的对象。

11. You can use a URN to talk about a resource without implying its location or how to dereference it.

可以用URN表示资源,而不用指明资源的位置或者如何取消对它的引用。

12. Doing so usually leads to a crash as soon as we attempt to dereference the uninitialized pointer.

因此，在对未初始化的指针进行解引用时，通常会导致程序崩溃。

13. In PHP 4, you could not directly dereference objects which are returned from methods. You would have to first assign the object to a dummy variable and then dereference it.

在PHP4中,你不能直接从一个方法中返回的对象中解析,你必须将这个对象注册给一个中间变量,然后解析它。

14. If an exception is thrown by a slot call, or if the combiner does not dereference any slot past some given slot, all slots after that slot in the internal list of connected slots will not be invoked.

如果有插槽调用抛异常，或者合并器在某些插槽之后就不再解引用任何插槽， 则内部已连接插槽链表中，该插槽之后的所有插槽将不会被调用。

15. If there is no dereference, then the pointer itself is being changed.

如果没有使用解引用操作，则修改的是指针本身的值。

16. Assigning to the result of a dereference assigns a new value to the indexed element.

对解引用操作的结果赋值是赋一个新值到相应的元素。

17. Common coding errors reported by the tool include buffer overrun, un-initialized memory, null pointer dereference, memory and resource leaks.

工具报告的常见编码错误包括缓冲区溢出、内存未初始化、空指针取消引用以及内存和资源泄漏。

18. The pointer-to-member dereference operator ( .*) fetches the member from an object or reference.

成员指针解引用操作符（.*）从对象或引用获取成员。

19. All iterators support the increment operator to navigate from one element to the next, and the dereference operator to access the element value.

所有迭代器都支持自增操作符，从一个元素定位下一个元素，并提供解引用操作符访问元素的值。

20. In other words, don't take an address that a user-mode application provides and treat that address as a pointer that we can directly dereference.

换句话说，不要提取一个用户模式应用提供的地址，并且把那个地址看成一个我们可以直接废弃的指示器。

21. But you don’t have to explicitly dereference a class-type variable to access the object it points to.

然而，为了访问类类型变量指向的对象，不必（严格来说是不允许）明确地对变量解除参照。

22. The arrow operator ( ->) as a synonym for (*it).member that is, dereference the iterator and fetch a member from the underlying object.

用于读取元素的解引用操作符（*），此操作符只能出现在赋值运算的右操作数上。

23. The one case where it matters that a throw expression throws the static type is if we dereference a pointer in a throw.

用抛出表达式抛出静态类型时，比较麻烦的一种情况是，在抛出中对指针解引用。

24. The parentheses are required due to the precedence of the addition and dereference operators.

由于加法操作和解引用操作的优先级不同，上述表达式中的圆括号是必要的。

25. The program contains a null pointer dereference.

程序包含一个空指针引用。

26. null pointer dereference

空指针引用

27. The second method uses a macro such as XBYTE[] to dereference a pointer.

第二种方法使用一个巨集，如XBYTE[]来解除对一个指标的管制。

28. The dereference operator is not required to be a member, but it is usually right to make it a member as well.

解引用操作不要求定义为成员，但将它作为成员一般也是正确的。

29. The dereference and arrow operators are often used in classes that implement smart pointers ( Section 13.5.1, p. 495).

解引用操作符和箭头操作符常用在实现智能指针（第13.5.1节）的类中。

30. The dereference operator has a higher precedence than the addition operator.

解引用操作符的优先级比加法操作符高。

31. The dereference operator returns an lvalue; we may assign to the value returned from the dereference operator, which has the effect of assigning a new value to the underlying element.

解引用操作符返回左值，因此可为其结果赋值，等效于为该指针所指向的特定对象赋新值。

32. Dereference returns an lvalue, so we may use a dereference operator as the left-hand operand of an assignment.

解引用返回左值，因此可将解引用操作符用作赋值操作的左操作数。

33. The arrow operator ( ->) provides a synonym for expressions involving the dot and dereference operators. The dot operator ( Section 1.5.2, p. 25) fetches an element from an object of class type:

语言为包含点操作符和解引用操作符的表达式提供了一个同义词：箭头操作符（->）。点操作符（第1.5.2节）用于获取类类型对象的成员：

34. The iterator types define the dereference operator to return the object to which the iterator refers.

迭代器类型定义了解引用操作符来返回迭代器所指向的对象。

35. The locked objects class (Zend_Memory_Container_Locked) guarantees virtually the same performance as working with a string variable.The overhead is a single dereference to get the class property.

锁定的对象类(Zend_Memory_Container_Locked)保证了和处理字符串变量差不多的性能.
