Question

I have an int called setupStage. This is simply a value I increment at the completion of each stage, so I can say, if (setupStage == 2), and I know that I am at the third stage (it defaults to 0).

Is there a way I can refer to these numbers in a better way? For example:

if (setupStage == stageEnterName)

Instead of having to refer to its actual raw int value.

It may be a misconception, but does what I am trying to achieve have anything to do with defining macros?

Yes!

Try this:

typedef enum {
    MyType0,
    MyType1,
    MyType2,
    MyType3
} MyType;

This is the same thing as this:

typedef enum {
    MyType0 = 0,
    MyType1,
    MyType2,
    MyType3
} MyType;

The values default to 0 at the first slot and then increment by 1 automatically. Note that the token names (MyTypeX) are arbitrary string values you set.

In this case they go from 0 to 3. Then you can say something like this:

if (setupStage == MyType3)

Which is identical to

if (setupStage == 3)
