I could not understand the question at all!

Xcode is giving an error even if I use one external parameter now two parameters are too much problem Can anyone explain me what is going on here?

functions.swift
// Enter your code below
func value divisor getRemainder(a: Int, b:Int) -> Int
{
    return a % b
}

Hi there,

The name value and divisor are designed to improve the readability of the parameters. Currently, they just called a and b so adding a label before them allows someone using the code to use the alternative name. To do this, before a add the label value and before b add divisor.

That all looks like:

func getRemainder(value a: Int, divisor b:Int) -> Int {
    return a % b
}

In the next task, you'll use these labels when you call the function.

I hope that helps,

Steve.

No problem! :+1:
