Problem with Twofer Kotlin Problem

[tawny wadi]

I wrote the correct code for the twofer problem:

fun main() {
    val name = readLine()
    val output = twofer(name)
    println(output)
}

fun twofer(name: String?): String {
    return if (name != null) {
        "One for $name, one for me."
    } else {
        "One for you, one for me."
    }
}```

But it keeps telling me:
```kt
[ERROR] src/test/kotlin/TwoFerTest.kt:[9,56] No value passed for parameter 'name'```

It also runs fine on an online compiler:

remove your main function. It's interfering with the testing setup

You might want to read about Default Arguments: https://kotlinlang.org/docs/functions.html

I understand you

So the default value of the String parameter will be an empty String.

In your code, what do you use when the input is null?

[tawny wadi]

When the input is null, it would display One for you, One for me

[tacit sparrow]

So, what's the default name?

[tawny wadi]

you

Are you OK now? Tests passing?

[tawny wadi]

Not yet

[tacit sparrow]

Let us know what code you have now. Make sure to read the "default arguments" link I gave you.

Got it. Very simple.

I read a Kotlin book deeply and I came back to solve the problem

Increase your chance of getting help and look like a pro by sharing codeblocks not images. For example, you can type the following. Note, the ``` must be on their own line.
```
for number in range(10):
total += number;
```
Discord will render that as so:

for number in range(10):
    total += number;
