Example of Enum Example of Macro Conclusion Learn the fundamentals of C by watching the video below: What is Enum in C? In C programming, an enum (enumeration) is a user-defined data type that is used to define a set of named integral constants; these constants are also known as enumera...
1. How to declare an enum in C#? The following code example declares three enums, Day, Month, and Color, using C# and .NET. // Day enum represents number of days in a week enum Days { Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday }; // Month enum represents months...
Example 3: Printing enum's constant name and value using foreach loopHere, we are using Enum.GetValues(typeof(Days) which returns an array of all enum values and to get the name of enum, we are using Enum.GetName(typeof(Days), day). Here, Days is the enum name and day is the ...
We use ‘enum' keyword for its implementation. It is related to #define preprocessors in C/C++. It can also be defined to represent integer numbers. Let's understand by comparing it with #define preprocessorFor example:#define JAN 1 #define FEB 2 #define MAR 3 #define APR 4 ...
To do this we supply an optional accumulator (10 in this example) to be passed into our function; if no accumulator is provided, the first element of the enumerable is used as the starting accumulator, and the function processes the remaining elements:...
We can understand the above example like this,Red = 1 << 0, // 0001 - 1means that for a given value, if the last bit is 1, we say the value contains the "Red flag", otherwise not contains. System.Enum# the base class for enumerations ...
’ names inside the enumeration to string in C#. We can use theToString()functionwith the instance of an enumeration to convert the value’s name inside the enumeration to a string. The following code example shows us how to create an enumeration of strings with theToString()function in C#...
You can pass enums to member functions just as if they were normal objects. And you can perform arithmetic on enums too. For example we can write two functions, one to increment ourenumand the other to decrement ourenum. 你可以把枚举传递给成员函数就好像它们是普通的对象。你也可以在枚举上...
Instead of callingEnum.GetValues(Type type)and passing in the type of our enumeration using thetypeofkeyword, we can pass ourDayOfWeekenumeration as a type parameter: vardaysOfWeek = Enum.GetValues<DayOfWeek>(); By calling Enum.GetValues this way, the return type is anIEnumerable<DayOfWeek>so...
For example, if we use the colors of the rainbow, which are Red Orange Yellow Green Blue Indigo Violet If enums didn't exist, you might use a#define(in C) orconstin C++/C# to specify these values. Eg Too Many Ints to Count!
