In the above code snippet we have defined conversion of enum value to string. We have taken class asenumsampleand we defined the enum asTutorialsand we declare the constants incsharpas csharp as1 andhtmlas 2 and
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 can be used as a base class constraint (...
Note: The most important advantage of "enum" over macro is: "enum" has its scope. That means "enum is only visible within the block it was declared."Example of C++ enumeration#include <iostream> using namespace std; int main() { enum week{SUN=1,MON,TUE,WED,THU,FRI,SAT}; enum ...
Now, there's one interesting caveat here:DiplomatOption<Foo>is not two scalars, it's an aggregate containing a type of class MEMORY, which means in some cases the Foo field will get interpreted as a blob of bytes rather than a scalar. Off the top of my head, given how we use these ...
be used to represent NULL pointers; in other words, wherever you were writing NULL before, you should use nullptr instead. It's no more clear to you, the programmer, (everyone knows what NULL means), but it's more explicit to the compiler, which will no longer see 0s everywhere being...
* Five words (20/40 bytes) are available in this union. * WARNING: bit 0 of the first word is used for PageTail. That * means the other users of this union MUST NOT use the bit to * avoid collision and false-positive PageTail. ...
This means the individual flags in combined enumeration constants do not overlap. Consider creating an enumerated constant for commonly used flag combinations. For example, if you have an enumeration used for file I/O operations that contains the enumerated constants Read = 1 and Write = 2, ...
That means that you only need to write the case name: enum ColorName: String { case black case silver case gray case white case maroon case red // etc. } You can further reduce your typing by separating the cases with commas using the keyword case just once. Add the following code ...
Further reading: https://www.tutorialsteacher.com/csharp/csharp-enum Swift Swift's enumerations are closer to union types, but still called enumerations. (Go figure.) They form a full fledged type with limited legal values. That means the type has to be capitalized, and the values not. ...
This means that the second 'if' statement is senseless. V650. Type casting is used 2 times in a row. The '+' operation is executed. Probably meant: (T1)((T2)a + b). V651. Suspicious operation of 'sizeof(X)/sizeof(T)' kind, where 'X' is of the 'class' type. V652. ...
