Is overriding std::to_string for user defined enums the proper way to provide to_string for user defined enums?

Tag : cpp , By : user116330

Any of those help That's not "overriding" (which applies to virtual functions), and you haven't added a "specialization" (which applies to templates), you've added an overload, which adds a declaration and definition of a new function to namespace std and that's forbidden:

New to C#, can anyone explain to me how enums and setting variables for enums works?

I think the issue was by ths following , 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 enum type "States" that you defined in the line before. What you can't see in your code is that by default in c# the underlying type for your enum is an integer, and each of your possible values also has an integer value assigned to it which could be overridden if needed, so all you're really doing in your update code is an integer comparison. Is there any reason you're not using a switch instead of that big if/else block? Also you could eliminate the start function and just instantiate your myState variable like this:
private States myState = States.cell;

Strict aliasing rule uint8_t buffer to structure

will be helpful for those in need
I had suggested that proposed approach does not follow strict aliasing rule
typedef union
   uint32_t var;
   uint8_t  bytes[4];
} Message;

uint8_t buffer[4];
Message* ptrMsg = (Message*)buffer;
uint32_t var1 = (ptrMsg->var >> 8);
uint8_t  var2 = (ptrMsg->var >> 4) & 0x0F;
uint8_t  var3 = (ptrMsg->var) & 0x0F;
