you don’t need the index

[Ruckus]

You don't need var i: Int

fun loadArray(n: Int, v: Array<Int>) {
    repeat(n) {
        v[i] = random()
    }
}

[Steve]

for (number in array) { number = random() }

[Ruckus]

@Steve That won't work...

[Ruckus]

@Roberto Messina If you want an array of random integers, you could use

val v = IntArray(n) { random() }

[Steve]

that’s more Kotliny

[Roberto Messina]

No, that function doesn't do anything. If you want to update the first n options of an existing array, use the first example I showed. My second example eliminates the need for the function if your purpose is just to create an array of random ints.

[Roberto Messina]

i wanna do that but in a function

[Ruckus]

Do what?

[Steve]

there’s zero reason to have a function to do that

[Steve]

what you’d want to do, is have loadArray take the n, and return an array, if you really want it to be a method

[Roberto Messina]

wait... i send my code

[Roberto Messina]

sorry if it's write in italian

[Steve]

yeah, take the first method that would take an array, and just have it return one

[Roberto Messina]

Thank you for your help, now my code work 😍

Wait, can’t you use .withIndex()?

[Evan R.]

fun loadArray(v: Array<Int>) {
    for ((index, value) in v.withIndex()) {
        v[index] = random()
    }
}
