Is it possible to pass an arbitrary number of arguments to a function?

Yes, in Go you can pass an arbitrary number of arguments to a function using variadic parameters. This is done by using the syntax ... before the parameter type in the function declaration. For example:

func sum(nums ...int) int {
    total := 0
    for _, num := range nums {
        total += num
    }
    return total
}

func main() {
    result := sum(1, 2, 3, 4)
    fmt.Println(result) // Outputs 10
}

In this example, the sum function accepts any number of integer arguments and returns their sum.
