C/C++ 中,static const、#define 和 enum 都可以用来定义常量,但它们在使用场景、编译方式和语义上存在一些区别。#define 最简单,但易出错,慎用,const 类型安全,功能强大,enum 用于定义一组相关常量。在实际开发中,根据具体需求选择合适的关键字,可以写出更加优雅的代码。 1、#define 宏 #define是 C 和 C++ 中...

在Java中,枚举类型(enum)是一种特殊的类,用于表示一组固定的常量。在类中定义枚举,可以使代码更加清晰、易于维护,并提供类型安全。下面我将分点详细解释如何在Java类中定义枚举,以及枚举的用途和好处。 1. 理解枚举类型的基本概念 枚举类型是一种特殊的类,用于表示一组固定的常量。在Java中,使用enum关键字来定义...
#include<iostream> using namespace std; enum Gender {MALE, FEMALE, OTHERS}; int main() { Gender gen = Gender.FEMALE; return 0; } By default, the value of the first name is 0, the second name has the value 1, and the third has the value 2, and so on. But these values don't...

Although this behavior is expected, it's really not friendly to developer. Values in different enums don't conflict with each other in Java. 👍 63 ️ 2 Copy link Contributor TeBoring commented Dec 10, 2018 • edited Loading The general proto syntax has to taken all supported langu...
#define is used to define some values with a name (string), this defined string is known as Macro definition in C, C++ while const is a keyword or used to make the value of an identifier (that is constant) constant. #define is not scope controlled whereas const is scope controlled...
