Hi - I am seeing enum members being used, with just the member's
name, and not the enum name.

for example:

Expand|Select|Wrap|Line Numbers

1. typedef enum Fruit
2. {
3. Apple = 0,
4. Orange,
5. Banana = 0xFF
6. } FruitIndex;
7.  
8.  
9. int arrayInt[Orange]
10. {
11. more code here.....
12.  
13. }
14.  

Question 1 - Is Orange's index = 1 ??
Question 2 - what do you think the 0xFF hex is fox??
QUESTION 3 - in the array - why don't I have to put
[FruitIndex.Orange] to access the member??

thanks!
p.s. this is NOT a homework question - i am at work not understanding
how this stuff works.

That's how they work.

for example:

1.       typedef enum Fruit
2.       {
3.          Apple = 0,
4.          Orange,
5.          Banana = 0xFF
6.        } FruitIndex;
7. >
8. >
9.       int arrayInt[Orange]
10.       {

Expand|Select|Wrap|Line Numbers

1.  
2. This is not valid syntax.

So, what is the point of having created a enum name FruitIndex with a
member Orange, if we don't use FruitIndex as an entity?

for the same reason we have the name "int" even though we don't write
"int.42".

Either "enum Fruit" or "FruitIndex" is the name of the type you've
created. You can, for example, declare objects of that type:

FruitIndex obj;

obj = Banana;

(Due to C's strange rules, the constant Banana is actually of type
int, but you can assign its value to an object of type FruitIndex.)
