What is arbitory order in an array

Answer 1

You have finished a lot of language tutorials. What's up with that? Shouldn't you know these things?

Answer 2

Arbitrary order means random order.

Answer 3

Do you mean arbitrary?

It means that the elements of the array are not ordered by size or anything, but can have any order.

Answer 4

An array will not reorder the elements without you knowing. You can put them in an arbitrarily chosen spot, and then they will remain just there.

Answer 5

Let's say you have the numbers 1, 2, 3, 4, 5.

An array doesn't mind in which order you store them. Could be...

[1, 2, 3, 4, 5],
[5, 4, 3, 2, 1],
[2, 1, 4, 5, 3]

... or really any other imaginable order.

What part of the tutorial are you referring to?

Answer 6

Keeping data in any order means not much but while using arrays for display you have to sort. In that case for example if you are using an array which you have to sort every time you display it would be good practice to sort it once and store it as sorted will reduce the cpu usage by not sorting it every time you use.

Answer 7

Thanks

Answer 8

Can you give me an exampl, please

Answer 9

Then, how to access it

Answer 10

Suppose, if I access as index - 0 then, each time it will return different value ?

Answer 11

How to know order of element for accessing element, and where it is useful ?

Answer 12

Ok

Answer 13

Arbitrary position is an index in array. Am I right ?

Answer 14

When you create your array it has its own index

arrArray=['data1','data5','data3','data12]

When you look at it you can say there is no order right??
Infact there is for the array

When you print arrArray[0] which is first record in array will be 'data1'
So
arrArray[0] ==> data1
arrArray[1] ==> data5
arrArray[2] ==> data3
arrArray[3] ==> data12

Every time you use arrArray[2] you get data3 so arrays has their index but this order won't look nice we call this arbitrary, this order happens by creation.

Yes you can create an array with ordered list but in any case array does not care what you stored in them and it will be arbitrary for it.

We use dictionary instead of array which is still array at the end but with your own indexes.

I hope this helps
