How to use enum values?

Question

I have the following enum:

enum Crank { X = 0, Y = 1 }

However when I try

if (x == Crank.X)

I get an error indicating

cannot convert from Crank to int

Where do i go wrong?

Assuming `x` is an int, you can cast the enum value to an int to compare them, i.e. `if (x == (int)Crank.X)` — stuartd, Jul 22 '16 at 22:55
thanks. however why do I need to cast it?? I gave it value 0... — Natalia Userbon, Jul 22 '16 at 22:56
From docs: The underlying type specifies how much storage is allocated for each enumerator. However, an explicit cast is necessary to convert from enum type to an integral type. — guipivoto, Jul 22 '16 at 22:57
See [Why enums require an explicit cast to int type?](http://stackoverflow.com/questions/4728295/why-enums-require-an-explicit-cast-to-int-type) for a great explanation of why this is required. — stuartd, Jul 22 '16 at 23:02
@stuartd even though sure, it makes sense, but you can do `enum Crank : int { //values }` and it still won't let you. That is poor implementation, you should be able to compare ints if you define it to only take ints. — Dispersia, Jul 22 '16 at 23:12

If x is of type integer, you need to cast the enum value to an int to compare if(x==(int)Crank.X)
