I don't understand why there is that error

Parameters cannot be reassigned

parameters are considered to be

final

Roberto, you only need to create the array inside the function and return it, don’t pass it as a parameter. This way of using mutable “out parameters” is very C-style 🙂

yes, cause i know C, C++ and C#

Right, there’s no need to do that in Kotlin, just remove the

v

parameter and return the one created inside the function. You can even shorten the declaration to:

fun loadArray(n: Int) = IntArray(n) {/*...*/}

function expressions and type inference can help shortening the code
