条款1:视C++为一个语言联邦 条款2:尽量以const,enum,inline替换#define 对于单纯常量,最好以const对象或enum替换#dedine 对于形似函数的宏,最好改用inline函数替换#define 条款3:尽可能使用const 将某些东西声明为const可帮助编译器侦测出错误用法。const可被施加于任何作用域内的对象,函数参数,函
enum枚举: set: C++枚举类型详解 名的枚举类型;不同枚举类型的枚举元素不能同名。 三、枚举元素说明1.将会为每个枚举元素分配一个整型值,默认从0开始,逐个加1。2.也可以在定义枚举类型时对枚举元素赋值,此时,赋值的枚举值为所赋的值,而其他没有赋值的枚举值在为前一个枚举值加1.2.枚举值是常量不是变量,不能...
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...

In one word, using const is better than define. enum is the best. There are lots of discussions. I put a great paper below. https://betterembsw.blogspot.com/2017/05/define-vs-const.html The compiler might generate storage for a constant object, even though the program doesn't really ...
High-level languages like Java and Python allow these characteristics through various programming constructs. Inheritance is an OOPs feature that allows code to be written once and implemented multiple times. Thus, reusing code for several operations is the main essence of inheritance. In this ...
