Introduction to Typedef and Enum in C Overview: In this tutorial, we will explore two important concepts in C programming: typedef and enum. Both typedef and enum are used to make code more readable, maintainable, and less error-prone, which is essential in larger or more complex projects. ...
typedef enum { RED, GREEN, BLUE } Color; 在这个示例中,我们使用typedef声明了一个名为Color的枚举类型,并且省略了枚举类型名称。这样,我们可以直接使用Color来定义变量,而不需要使用枚举类型名称。 需要注意的是,虽然使用typedef可以使代码更加简洁,但是过度使用typedef可能会使代码更加难以理解。因此,应该根据具体...
In C, the difference between the two approaches is purelysyntactic: enum weekday {sun, mon, tue, wed, thu, fri, sat}; is essentially equivalent to typedefint weekday; const weekday sun = 0, mon = 1, tue = 2, wed = 3, thu = 4, fri = 5, sat = 6; ...
Enum的作用就是把一串名字和一串整型联系在一起, 可以说在c中Enum完全可以被#define取代, 比较鸡肋的 enum sizes { small=7, medium, large=10, humungous }; 如果不赋值, 会从0开始递增, 或从赋的值开始递增 Enum一个优点, 便于debug There is one advantage to enums: unlike #defined names which are ...
typedef enum { c1, c2 } tMyEnum; typedef struct { int i; double d; } tMyStruct; can be better written as enum tMyEnum { c1, c2 } struct tMyStruct { int i; double d; }; Is that correct? What about C? Share Improve this answer Follow answered Feb 5, 2009 at 15:31 x...
};voidmain() {enumlevel l1=司令;enumlevel l2=军长;enumlevel l3=师长; printf("%d\n",l1); printf("%d\n",l2); printf("%d\n",l3); system("pause"); } 三、typedef #include<stdio.h>#include<stdlib.h>typedefintaa;//typedef没有创建数据类型,给已经有的数据类型起一个别名.编译时处理,仅...

比如，类型可以作为类/名字空间的一个成员。比如：template <int opengl_type_enum> struct TypeHelper ...
Unfortunately, this is not entirely accurate. I wish it were that simple, but it's not. C++ can't generate such typedefs for structs, unions, or enums without introducing incompatibilities with C. For example, suppose a C program declares both a function and a struct named status: ...
