解释警告信息 "enum constant in boolean context [-wint-in-bool-context]" 的含义 这个警告信息表示在布尔上下文中使用了枚举常量。在C或C++中,布尔上下文期望一个布尔值(true 或false),而不是整数或其他类型的值。枚举常量在底层实现中通常被表示为整数,因此直接在需要布尔值的上下文中使用枚举常量可能会引发逻辑...
These statements are defining 1, 2, 3 and 4 by constant name JAN, FEB, MAR and APR respectively. Here we need to define each value separately.But, in case of "enum" there is no need define each value. We can define and access different values (but integral/integer types) by a name...
In this article, we’re going to look at some of the ways we can enumerate an Enum in C#. Enums allow us to declare a group of related constant values in a readable way where the underlying data type is usually an integer. To download the source code for this article, you can vis...
Example 3: Printing enum's constant name and value using foreach loop Here, we are usingEnum.GetValues(typeof(Days)which returns an array of allenumvalues and to get the name ofenum, we are usingEnum.GetName(typeof(Days), day). Here,Daysis theenumname anddayis the index. ...
Flags Enum# bit flags, means that usea bit field to stand for a value, so often used with bitwise logical operators(AND, OR, EXCLUSIVE OR) define values bepower of twoto avoid overlap UseNoneas the name of the flag enumerated constant whose value is 0. ...
Retrieves the name of the constant in the specified enumeration that has the specified value. GetName<TEnum>(TEnum) Retrieves the name of the constant in the specified enumeration type that has the specified value. GetNames(Type) Retrieves an array of the names of the constants in a ...
enum音标为[ɪˌnjuːm]拓展:1、enum释义:枚举;枚举类型;列举 2、enum造句:(1)Just as with any constant, all references to the individual values of an enum are converted to numeric literals at compile time.与任何常量一样,对枚举中各个值的所有引用在编译时均将...
type is usually obtained using atypeof expression. The second one is defined as a basic object. It is used to specify either the integer value or a string containing the name of the constant to find. The return value is aBooleanthat is true if the value exists and false if it does ...
Retrieves the name of the constant in the specified enumeration that has the specified value. GetName<TEnum>(TEnum) Retrieves the name of the constant in the specified enumeration type that has the specified value. GetNames(Type) Retrieves an array of the names of the constants in a ...
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...
