How to define an enumerated type (enum) in C - An enumerated type declares an optional type name and a set of zero or more identifiers that can be used as values of the type. Each enumerator is a constant whose type is the enumeration. For example, if y

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...
In the above class definition, you can see that Status is one of the properties of the Todo class. The possible values are defined in theenumyou previously created. When you instantiate an instance of the Todo class, you are able to choose from these defined values. ...
First, let's say that there is no real enum type in Godot, not in the Kotlin meaning of it. At best, they are like C enum, a simple namespace for a limited set of Integer constants. Godot 4 with GDScript 2 finally added a bit of type safety by allowing the use of enums directl...
A typical use might be to signal the ‘end’ of the enum, which could be used to identify where the last value in the enum is. If values are added, then this value could be changed, to represent the last of the additional values. Including sentinels confuses the meaning of the enum....
, meaning it may or may not be legal and you have to explicitly check it. (Optionals are essentially a syntactic Maybe Monad, and way off topic.) You can even define an enumeration in terms of itself, which is just all kinds of weird. From the documentation: indirect enum Arithmetic...
, 0. C# enums are type safe meaning. You cannot implicitly convert from the underlying type to the actual enum. Also, you cannot assign a value of one enum to another enum, even though the underlying types of both the enums are same. An explicit cast is always required....
we just need to check to see if the & operation is not zero. If any of the bit positions match, it will return the sum of those values, but we don’t care if it is exactly the same as the colorsToMatch value, only that it isn’t zero meaning that there is at least one color...
name. This can add character or meaning to your game world, or it can be used to help disguise the underlying math, resulting in a game where the underlying mechanics are masked away from the player, leading to a more mysterious experience where they need to experiment and discover. What’...
