Enum and strings


Enum and strings

I think the issue was by ths following , , Try the following approach
code :
#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' ) s[n - 1] = '\0';

    b = dog;
    if ( strcmp( animal_name[b], s ) == 0 ) printf( "Y\n" ); 
    else printf( "N\n" );

    return 0;
}
Y

it fixes the issue
The problem is that the last line throws this error: Implicit conversion of tipoServidor (aka enum tipoServidor) to NSString * is disallowed with ARC
code :
NSString *DescriptionOfServidor(tipoServidor e) {
    switch (e) {
        case SERVIDOR_ARG: return @"SERVIDOR_ARG";
        case SERVIDOR_EU: return @"SERVIDOR_EU";
        case SERVIDOR_US: return @"SERVIDOR_US";
    }
    return nil;
}
NSString *server = DescriptionOfServidor([settings servidorType]);

will be helpful for those in need The way to approach problems like this is for the class in question to have a private constructor, and to have public static field/properties that are initialized with values of that instance. This is a way of having a fixed finite number of immutable instances of that type, while still allowing methods to accept parameters of that type.
The following code is valid C# 6.0.
code :
public class Command
{
    private Command(string value)
    {
        Value = value;
    }

    public string Value { get; private set; }

    public static Command SET_STB_MEDIA_CTRL { get; } = new Command("SET STB MEDIA CTRL ");
    public static Command ECHO { get; } = new Command("ECHO");
    public static Command SET_CHANNEL { get; } = new Command("SET CHANNEL ");
    public static Command GET_VOLUMN { get; } = new Command("GET VOLUMN");
    public static Command GET_MAX_VOLUMN { get; } = new Command("GET MAX VOLUMN ");
    public static Command SET_STB_MEDIA_LIST { get; } = new Command("SET STB MEDIA LIST ");
}

wish of those help You can use if-else or switch statements to determine which enum to use, and then use valueOf():
code :
String e = "Days";
String value = "Monday";

if (e.equalsIgnoreCase(Enumerations.Days.class.getSimpleName())) {
    System.out.println(Enumerations.Days.valueOf(value).getValue());
} else if (e.equalsIgnoreCase(Enumerations.Months.class.getSimpleName())) {
    System.out.println(Enumerations.Months.valueOf(value).getValue());
} else {
    System.out.println("Could not find enum");
}
MON
String e = "Days";
String value = "Monday";

String res = Arrays.stream(Enumerations.class.getDeclaredClasses())
        .filter(c -> c.getSimpleName().equalsIgnoreCase(e))
        .findFirst()
        .map(c -> {
            String result = null;
            try {
                Object o = c.getMethod("valueOf", String.class).invoke(null, value);
                result = (String) o.getClass().getMethod("getValue").invoke(o);
            } catch (IllegalAccessException | InvocationTargetException | NoSuchMethodException e1) {
                e1.printStackTrace();
            }
            return result;
        }).orElse("Could not find");
System.out.println(res); //prints MON

I think the issue was by ths following , You can use static in combination with enum if you are mostly interested in using the enum for constants
code :
enum CompassPoint {
    static let n = "Nort"
    static let s = "South"
    static let e = "East"
    static let w = "West"
}
