在 C++ 编程中，枚举类型（enumeration type）是一种用户定义的数据类型，它由一组命名的整数常量组成。这些常量通常被称为枚举子（enumerator）。枚举类型的引入简化了代码的可读性和维护性，使得程序员能够以更直观的方式处理特定范围内的值。本文将深入探讨 C++ 中的枚举类型，包括其基本概念、声明方式、使用场景以及...
Example: Enumeration Type #include<stdio.h>enumweek {Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday};intmain(){// creating today variable of enum week typeenumweek today; today = Wednesday;printf("Day %d",today+1);return0; } ...
1 首先，请看下面的语句：enum enumType {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday};这句话有两个作用：第一：声明enumType为新的数据类型，称为枚举(enumeration);第二：声明Monday、Tuesday等为符号常量，通常称之为枚举量，其值默认分别为0-6。（后面会介绍怎样显式的初始化枚举量的...
enumBOOLEAN/* Declares an enumeration data type called BOOLEAN */{false,/* false = 0, true = 1 */true};enumBOOLEAN end_flag, match_flag;/* Two variables of type BOOLEAN */ 还可将此声明指定为 C复制 enumBOOLEAN {false,true} end_flag, match_flag; 或指定为 C复制 enumBOOLEAN {false,t...
枚举类型(Enumeration)是一种用于列出所有可能值的数据类型。在程序中,我们可以使用枚举类型来表示具有固定值的整型常量。 枚举的应用场景: 「代替常量」:枚举类型可以用来代替常量,从而使程序更易读。例如,我们可以定义一个表示星期几的枚举类型,用来代替用数字表示星期几的常量。

1.枚举类型 1.枚举数据类型是C语言中一种构造数据类型,可以让数据更加简洁,更易读,对于只有几个特定的数据,可以使用枚举类型 2.枚举对应英文enumeration,简写为enum 3.枚举是一组常量的集合,包含一组有限的特定的数据 4.枚举语法的定义格式为 enum 枚举名 {枚举元素} 1.1
Enumeration types are considered basic types. Type specifiers for enumeration types are discussed in Enumeration Declarations.The keyword void has three uses: to specify a function return type, to specify an argument-type list for a function that takes no arguments, and to specify a pointer to ...
Enumeration (or enum) in C - C enumeration (enum) is an enumerated data type that consists of a group of integral constants. Enums are useful when you want to assign user-defined names to integral constants. The enum keyword is used to define enums.
