dereference

dereference的音标是[dɪ"refəns] ，基本翻译是“引用；解引用；解引用材料；使还原；使恢复原状”，速记技巧是de-表示“去掉；除去；取消”。

"dereference"这个词的英文词源可以追溯到拉丁语"dereferencium"，意为“取消引用”。它的变化形式包括"dereference"（取消引用）和"dereferencing"（取消引用操作）。

相关单词：

1. "reference"：这个词与"dereference"有密切关系，都与引用有关。在"dereference"中，"dere"来自于"reference"，表示取消或解除引用，而"ference"来自于拉丁语的"ferre"，意为“携带”或“运送”。因此，"reference"意为“引用”或“提及”。

2. "dereferencing"：这个词是由"dereference"和"referencing"的组合而来，表示取消引用操作。

3. "derefernce"：这是一种错误拼写，但也可以看作是"dereference"的变形。

在句子中使用这些单词时，可以表达取消引用、参考、参考信息、参考源、参照、参照对象、参照物、回溯、追溯和指向等含义。

例如，当我们想要取消对某个对象的引用时，我们可以说："我们需要dereference这个对象"。当我们需要参考某个信息或数据时，我们可以说："我们需要referencing这个数据"。在计算机科学中，"dereference"通常用于表示对指针的解引用，以获取其所指向的数据。

Title: Dereferencing Pointers in C++

C++ is a popular programming language that uses pointers extensively in its syntax. Dereferencing is the process of accessing the value stored at a pointer"s address. It is essential for manipulating objects and arrays in C++.

When you create a pointer to an object or array, you are essentially creating a reference to it. To access the actual object or array, you need to dereference the pointer. This process can be tricky if you don"t understand how pointers work, but it becomes much easier once you get the hang of it.

Dereferencing a pointer in C++ can be done by using the arrow operator (->). For example, if you have a pointer named ptr that points to an object named obj, you can dereference ptr by using the statement ptr->property_name to access the property of the object pointed to by ptr.

Dereferencing pointers in C++ is a powerful tool that allows you to manipulate objects and arrays in ways that would otherwise be impossible without using pointers. It is essential for advanced C++ programming and should be mastered by every C++ developer.
