How do I access the an element in an enumeration by the associated number in C?

I have an enumeration in C as follows:

enum menu
{
    PASTA,
    PIZZA,
    DIET_COKE,
    MOJITO,
};

Since I haven’t explicitly mentioned the integer values corresponding to these elements, they are assigned values 0,1,2, and 3 respectively.

Say I decide to add another 100 or so items to my enum.
Then is there a way to access these elements by the number they are associated with?
(Like how we can access an element of an array using its index)

>Solution :

The enums are nothing but named constants in C. Same as you declare a const using

#define PASTA 0
#define PIZZA 1
#define DIET_COKE 2
#define MOJITO 3

for example.

With the enum the compiler does that for you automatically. So there is no way to access enums in a way you want in C, unless you create an array for them.
