Is it a good practice to use enum as int?

Question

So, I have a variable \"state\" in a class. I want to declare it as an integer so I can save some if statements.

int state;

One way to do t

Answer 1

Yes that is a good way to do it. You generally use enums to make life easier, a lot of different numbers that don't really tell other coders anything isn't quite helpful.

So this is a perfectly good way of using it, it makes your code readable and understandable.

Altough as @James McNellis pointed out, naming your enums like "1,2,3,4" is a bad idea, since it doesn't express what it really does.

But I suspect that was only an example from your side.

Consider this instead:

switch (operationState)
{
    case Waiting:
        dosomething();
        break;
    case Running:
        dosomething();
        break;
    case Ended:
        dosomething();
        break;
}

In this case, the "operation" is either: Waiting, Running or Ended, which makes it readable and understandable. Now consider the way without enums:

switch (iState)
{
    case 997:
        dosomething();
        break;
    case 998:
        dosomething();
        break;
    case 999:
        dosomething();
        break;
}

What does 997 tell you? Absolutely Nothing! Use readable and understandable code to make everyones life easier.
