Answer 3

enumeration is a user defined data type that consists of integer constants. you can read more here gives some more info https://en.wikipedia.org/wiki/Enumerated_type

Answer 4

one more thing, "enum" ( unscoped ) causes lots of bugs because of the main cause that variables that you declare are global while scoped enum the variables are local.
you should be using "enum class" ( scoped ) in C++.

ex .
enum Unit { Alpha, Beta, Gamma };
Unit u;
u = Alpha; // Alpha is global
int Alpha = 63; // Compiler generates errors

enum class Unit { Alpha, Beta, Gamma };
Unit u;
u = Unit::Alpha; // Alpha is local
int Alpha = 63; // Compiles fine.

I would recommend to read "Effective Modern C++" for more information about it.

An enumeration is a user-defined data type that consists of integral constants. To define an enumeration, keyword enum is used.

enum season { spring, summer, autumn, winter };
