Basic Scala programming questions. I will give a thumb up, thank you!

Consider the class below.

Identify each member of the class with the attributes that apply to it.

class BarkingDog(val name: String, val breed:String, val age: Int ) [ A list of shouts for the dog val listofShouts = List ("Wuffluff", "Bowliowllow", "ARuff ARuff", "Ruoff", "Meow") The current shout private var idx = 0 def bark() -{ /t Print the bark println(s"$(this.name, a proud $this.breed says $listofShouts (idx)!") /* Increment the index but wrap around to to avoid embarassing exceptions */ this. idx (this. idx + 1) %(listOfShouts.

Calling foo(bar(z) will result in a type mismatch error because the output type of bar (String) is not the same as the input type of foo (Int). b. baz takes in an input string and returns the number equaling the size of input string plus 7 C. Although foo's argument x is typed to be an Int, scala will correctly execute a call such as fool World") d. The value siz1 in baz will have the type String e. Changing the last statement of baz from foo(sizl) to eturn foo(sizl) does not change its meaning
