An enum is basically a special type that lets you define named values. You’re creating a named type just as you would if you were defining a class. What your code is actually doing is first defining your enumerated type called States with all the possible named values, then declaring a variable “myState” using the … Read more
Enum default uses int datatype for storing value you can set type for enum and override default datatype, but datatype must be of integral numeric type Example : enum Months : byte { Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec }; 4 solved Which data type the enumerations are stored … Read more
That’s not how enums work. You need something like this: private enum UserAgents { MSIE70, MSIE60, MSIE50 } But then you have to worry about getting the string value out of it, the flags don’t match the string representation either. You could decorate them with DescriptionAttributes but then you still have to do all the … Read more
create enum with file name EnumDay.java public enum EnumDay { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY,NAVEED } and testclass with file name EnumTest.java public class EnumTest { EnumDay day; public EnumTest(EnumDay day) { this.day = day; } public void tellItLikeItIs() { switch (day) { case MONDAY: System.out.println(“Mondays are bad.”); break; case FRIDAY: System.out.println(“Fridays are … Read more
In all versions of C++, the second version (Foo::States::BAR) using scope syntax is the more conventional and will be less surprising for future maintainers of your code. Since the value is a constant, there is no need for an instance of the class, so this is similar to how static methods are most often called … Read more
Let me explain your code for you: NSString *isoFormat = ISO8601DateFormatType; (assigns string ISO8601 to isoFormat) NSString *dateFormat = (isoFormat != nil) ? isoFormat : ISO8601DateFormatType; (isoFormat is never nil so the condition is always true. If it were false, we would again assign string ISO8601). NSDateFormatter *formatter = … (we get some formatter, it … Read more
I think what you are trying to do is making your code dynamic. Unfortunately, you are doing it completely wrong. Please first clear your concept on enum. If this is the case, then you can try this- int a, b; char op; cin >> a >> op >> b; switch(op) { case ‘+’: cout << … Read more
c++ Making a code that displays equations and keep getting the “expression must have integral or unscoped enum type” error solved c++ Making a code that displays equations and keep getting the “expression must have integral or unscoped enum type” error
Introduction Solution The error you are getting is likely due to the fact that you are trying to assign a value to a variable that is not of an integral or unscoped enum type. To fix this, you will need to make sure that the type of the variable you are assigning a value to … Read more
P0W’s answer is correct on both counts, but in case you simply want to output the underlying value, then it may be simpler to cast rather than overload the insertion operator. using enum_type = std::underlying_type<Apple::color>::type; enum_type value = (enum_type)Apple::color::green; std::cout << value << ‘\n’; 2 solved C++ How can I access to an inner enum … Read more
Introduction The Swift programming language is a powerful and versatile language that allows developers to create robust and efficient applications. One of the features of Swift is the ability to create enumerations, or enums, which are used to define a set of related values. However, when declaring an enum case, it is important to be … Read more
Swift enumeration cases are defined as case someName, not case .someName. This is an easy syntax error when declaring a new enum’s cases, as in most other situations you will be typing .someName via dot syntax. But when first declaring that enum case, it’s case someName without the period. enum SomeEnum { case one case … Read more
Try the following approach #include <stdio.h> #include <string.h> int main(void) { enum Animal { cat, dog, elephant }; char * animal_name[] = { “cat”, “dog”, “elephant” }; enum Animal b; size_t n; char s[100]; fgets( s , sizeof( s ), stdin ); n = strlen( s ); if ( s[n – 1] == ‘\n’ ) … Read more
For a bit mask it helps to look at values in binary since that is the level needed for a bit mask. And each enum value typically only sets a single bit. So the enum values would be set (in binary) to 00001, 00010, 00100, 01000, 10000, etc. Those same values in decimal would be: … Read more
I’m not sure what is your question, but as @crashmstr commented .. it seems you don’t need an Enum but you just need a class to hold these properties Any way you can use this BUT IT’S NOT A GOOD PRACTICE and I don’t know what do you want the setter to do public string … Read more
