Kick can be your friend.What is Typedef in C++? The same can be done with typedef :. Difference between typedef and macro in C.
The same can be done with typedef :. Using typedef , simplify the declaration of:. This, too, can be simplified using typedef :. Types, including typedefs and structure definitions. 模板别名(正式的名称为"templatetypedef "). Template alias(formerly known as"template typedef "). In particular, it must not achieve function type by means of a typedef . 为了便于理解,我强烈推荐你使用typedef 关键字。 To make it more understandable, I strongly recommend that you use a typedef . 例如,有一个reference的typedef ,而void&是没有意义的;. There's a reference typedef , for example, and void& makes no sense; 如果你使用了成员函数指针,你最好使用typedef 以防止混淆。 If you're using member function pointers, you should always use a typedef to avoid confusion. Typedef 定义以关键字typedef开始,后面是数据类型和标识符。A typedef definition begins with the keyword typedef, followed by the data type and identifier. Go甚至不允许类型之间进行隐式转换,在C中,只能是typedef 。 Go doesn't even allow implicit conversions between types that, in C, would just be typedefs . (a)完全不透明的对象(这种情况下要主动使用typedef 来隐藏这个对象实际上是什么). (a) totally opaque objects(where the typedef is actively used to hide what the object is). Chrono库定义三种主要类型以及工具函数和常用typedef 。 The chrono library defines three main types as well as utility functions and common typedefs . Typedef 由编译器来解释,而define语句则有预处理器来执行。Typedef interpretation is performed by the compiler whereas define statements are processed by the pre-processor. 如果使用此存储类,则无法使用任何其他存储类,如extern、static或typedef 。 If you use this storage class, you cannot use any additional storage class such as extern, static, or typedef . Typedef 是由编译器执行解释的,define语句是由预编译器进行处理的。Typedef interpretation is performed by the compiler whereas define statements are processed by the pre-processor. C的专门领域-声明,定义和可访问性,typedef ,const和volatile以及序列点. Specialized Areas of C- declarations, definitions and accessibility, typedef , const and volatile, and sequence points. C语言typedefC语言提供了typedef 关键字,您可以使用它来为类型取一个新的名字。 The C programming language provides a keyword called typedef , which you can use to give a type a new name. C语言中的一些特定内容-声明,定义,typedef ,const和volatile以及序列点. Specialized Areas of C- declarations, definitions and accessibility, typedef , const and volatile, and sequence points. Typedef:typedef 用于为已存在的甚至是自定义数据类型(如结构)提供新名称。Typedef: typedef is used to give a new name to an already existing or even a custom data type(like a structure). 下面我们讨论函数,但实际上这些方法或多或少适用于typedef ,结构体和全局变量。 Below we talk about functions, but really these same approaches apply, more or less, to typedefs , structures, and global variables. 使用struct,typedef 或class,将矢量和矩阵分别封装到一对称为vect和matrix的抽象类型中。 Using struct, typedef or class, encapsulate both vectors and matrices into a pair of abstract types called vect and matrix, respectively. 默认情况下,wchar_t是本机类型,但可以使用/Zc:wchar_t-使wchar_t成为unsignedshort的typedef 。 By default, wchar_t is a native type, but you can use/Zc: wchar_t- to make wchar_t a typedef for unsigned short. 这项差异随着程序员开始嵌套容器而更为显著,虽然在这种情况下typedef 是一个减少代码的好方法。 This difference grows as the programmer begins to nest containers, though in such cases typedefs are a good way to decrease the amount of code. Define是C指令,用于为各种数据类型定义别名,与typedef 类似,但是它们有以下几点不同:. Define is a C-directive which is also used to define the aliases for various data types similar to typedef but with the following differences-.
