Hi!
I want to define a special array. Right now it looks like this:

Code:

int translation[] = {
		1,
		2
};

But I would like to have it like this, so that the indexes are fixed:

Code:

int translation[] = {
		12 = 1,
		14 = 2
};

How to do that?

Greetings 🙂

Someone may need to correct me on this, but i don't think this is possible. It seems easiest to just do:

Code:

int translation[15];
translation[12] = 1;
translation[14] = 2;

Otherwise, you'd need to fill in the spaces with 0. Probably better to clear the memory anyway.

that should work just fine.

Code:

int[] array = new int[]; array[12] = 1; array[14] = 2

Which programming language do you want the answer in? Your source looks valid in C, Objective-C, and Java, depending on context. It may also be valid in other languages.

Code:

	int translation [] = { [12] = 1, [14] = 2 };

Type "c99 standard draft" into Google the find the latest draft of the C99 Standard; Objective C is also based on that standard.
