Array of size enum in C++

[xrax]

Is there a way to make an array that has the same amount of elements as an enum typedef?
typedef enum

{
A, B, C

} Enum_Types;

typedef double Enum_Array[ ??? ];

Use the last Enum value as your array size.

Enum_Array [C] in your case.

A common practice is to have hte enums as follows:

{A,
B,
C,
MIN= A,
MAX = C
}

Then make your array size MAX.

TYhen if the enum list ever changes ... you can reassign MAX as desired and all your code should still work. Imagine if you used C in 100 places then decided C nees to be deleted 😉
