Question about enum - Kimble - 09.12.2015

Questions in comments:

Код:

enum someEnum
{
    var1,
    var2,
    var3,
    var4,
    var5,  // On the last variable here does it matter if there's a coma or not? I like to put it cause it looks neat?
}; // Is the semicolon necessary here?

Thanks

The script complies with or without both (on the enumerator), where it is required is on arrays.

pawn Код:

enum eArray
{
    list_element_1[144],
    list_element_2[144],
    list_element_3[144],
}

static const aArray[][eArray] =
{
    {"", "", ""},
    {"", "", ""},
    {"", "", ""}
};

Re: Question about enum - Kimble - 10.12.2015

Awesome, one more question, is there a way to get the size of an element inside of an enumerator?
Like how would i find out that list_element_2 is 144 long?

I tried using sizeof() in different ways but keep getting errors...

The only way (that lets you to easily edit the destination size of a list element) that I can think of is:

pawn Код:

enum eArray
{
    list_element_1[144],
    list_element_1_so,
    list_element_2[144],
    list_element_2_so,
    list_element_3[144],
    list_element_3_so
};

static const aArray[][eArray] =
{
    {"", 144, "", 144, "", 144},
    {"", 144, "", 144, "", 144},
    {"", 144, "", 144, "", 144}
};

main()
{
    printf("%d", aArray[0][list_element_3_so]);
}

Or just input the size of a list element in to a function manually (when it is needed).

pawn Код:

strcat(aArray[0][list_element_3], "test", 144);

Re: Question about enum - dxhj - 10.12.2015

No, it doesn't matter. The compiler will accept with the last coma or not.

Of course, here's an example:

Код:

	
enum myEnum {
	foo[144]
}
	
new bar[myEnum];
sizeof(bar[foo]); /* 144 */

	foo[144]

new bar[myEnum];
sizeof(bar[foo]); /* 144 */

That doesn't apply to tridimensional arrays.

Код:

	
enum myEnum {
	foo[144]
}

new bar[5][myEnum];
sizeof(bar[]); // 144

Now, it does.

@EDIT

Sorry. I read bidimensional (almost sleeping haha). Anyway, the only change will be one [] more:

Код:

new bar[5][4][myEnum];
sizeof(bar[][]); // 144

1st:

pawn Код:

enum myEnum
{
    foo[144],
    fooo[256],
    foooo[120]
}

new bar[5][myEnum];
printf("%d", sizeof(bar[])); // 520

2nd:

pawn Код:

enum myEnum
{
    foo[144],
    fooo[256],
    foooo[120]
}

new bar[5][myEnum];
printf("%d", sizeof(bar[][])); // 1

pawn Код:

enum myEnum
{
    foo[144],
    fooo[5],
    foooo[5]
}

new bar[5][4][myEnum];
printf("%d", sizeof(bar[][])); // 154

We are trying to get the size of a single list element, not the size of each and every list elements in a enumerator.

It can't be done. Use arrays.

Re: Question about enum - Crayder - 10.12.2015

I'm just going to point out that enumerators can be used as tags...

Think of it like this (no this won't work, just an example):

pawn Код:

sizeof(eArray:list_element_2)
