C enum(枚举) C enum(枚举) 枚举是 C 语言中的一种基本数据类型,它可以让数据更简洁,更易读. 枚举语法定义格式为: enum 枚举名 {枚举元素1,枚举元素2,……}; 接下来我们举个例子,比如:一星期有 7 天,如果不用枚举,我们需要使用 #define 来为每个整数定义一个别名: #define MON 1 #define TUE 2 #de...
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 ...
system("pause"); } 二、枚举类型(限定取值) 枚举常量实质是整型数据 #include<stdio.h>#include<stdlib.h>//枚举的一般形式,限定在这个范围内取值//如果没有一个赋初值,就会从0循环到最后一个,每次加1//如果第一个赋初值,后面每个加1//除非自己赋值,否则计算机赋值会让每个枚举常量都不同enumlevel{ 司令=...

Quiz on Objective-C Typedef Explained - Learn about typedef in Objective-C, its syntax, and use cases for defining new data types to enhance code readability and maintainability.
Use of typedef enum in CWe can use the typedef and enum together in C programming. If we use typedef with enum in C then it increases the code readability and creates a new type for the enum. Let see an example, where I am creating a list of errors using the enum and defining a ...
