Now, why should we use enum?
Some of you have experienced enum.
Enum was added even to the C language,
and in many other programming languages, there are enumerated types.
It's a multiple choice question, just take a second, Can you use a named
integer instead of an enumerated type to get that kind of constant?
Can you use a #define much like in the pre processor keeping C
old style, for these enumerator constants like red and white.
Or is it best to have a small related set of constants?
So which reason exists for using enum?
It is quite true that, you can just use cost
declaration for example, if you wanted true and
false as two related constants, we can say,
constant TRUE is 1 and constant,
FALSE is 0 then we would have that.
We can also use this in old C style, but again, there's safety issues.
