In the C language, the constants that are defined by macros make it easier to organize the programming work because they can be used to associate an identifier with a constant value. But unlike the variables, a constant value can also be associated with an identifier. The ability to “label...
In this blog, you will learn what enumeration is and its implementation of code in the C programming language. This blog will guide you on when and how to use enumeration in C, including implementation in switch statements and flags. Further, we will be exploring the differences between enum...
Short for enumeration, an enumvariable typecan be found in C (ANSI, not the original K&R), C++ andC#. The idea is that instead of using anintto represent a set of values, a type with a restricted set of values is used instead. For example, if we use the colors of the rainbow, w...

Practice the following examples to understand the concept of enumeration (or, enum) type in C programming language.Example 1: Enum Constants Get Incrementing Integer ValuesC assigns incrementing integer values to each constant, starting with "0". When we assign val2 to the above variable,...
// yellow, green, blue are scoped to Color enum class Color { yellow, green, blue}; // fine, no other "yellow" in scope auto yellow = false; // also fine auto c = Color::yellow; 1.2 强类型枚举 非域内的枚举成员,可隐式的转换为广义整型 (integral types) enum Color { yellow, gr...
编程语言(programming language),是用来定义计算机程序的形式语言。它是一种被标准化的交流技巧,用来向计算机发出指令。一种计算机语言让程序员能够准确地定义计算机所需要使用的数据,并精确地定义在不同情况下所应当采取的行动。 编程语言的描述一般可以分为语法及语义。语法是说明编程语言中,哪些符号或文字的组合方式是...
enum X { A=3, B, C } X.min // is X.A X.max // is X.C X.sizeof // is same as int.sizeof The EnumBaseType of named enums must support comparison in order to compute the .max and .min properties. Anonymous EnumsIf the enum Identifier is not present, then the enum is ...
Home » C++ programming language (Enumeration) enum with example in C++In this article we will learn about enumeration, which is a user defined data type. We use ‘enum' keyword for its implementation. It is related to #define preprocessors in C/C++. It can also be defined to represent ...
In C and C++, it's always been important to express the idea of a NULL pointer--one that has no value. Oddly, in C++, the expression used, 0 (or NULL, always #defined to zero) was not even apointertype. Although this worked most of the time, it could lead to strange and unexpe...
