I do not understand one of the fields in the struct?

closed account (yR9wb7Xj)
Can someone explain what is going on inside the struct function? I'm really confuse why MonsterType Type; is written likes this? It's not declare anything I don't think. This solution is not mine it's a solution from another site that I found, I'm trying to understand what is going on in the code.None of these are not my comments either it came with the solution the only one that is mine is the one I'm asking a question on that has the two brackets. Thanks

MonsterType is a user-defined enumerated constant.

So you can know what type of monster you create by a name such as OGRE instead of by a "magic" hard-coded number.

Okay so are you saying in this line of code MonsterType type; inside the struct, what it's doing it's passing the enum class called MonsterType into the field of the structure that is declare to the variable type? Right?
