Apple Swift Coding I - Lesson 11-16 (REORDER)

Choose the code snippet that would produce the error:

Invalid reeducation of ‘myFirstWord’

• let myFirstWord = "juice"

  let myFirstWord = "banana"

• let myFirstWord = "bye"

  myFirstWord - "anemone"

• myFirstWord = "uh oh"

• var myFirstWord = "indubitably"

  myFirstWord = "dada"

  myFirstWord = 1

What will this code snippet print out?

let number = 100

if number > 99 {

print ("What a smallish number !")

{ else if number < 150 {

print ("That's not so big.")

{

print ("Goodbye.")

• “What a smallish number!”

• “What a Smallish number!”

• What a Smallish number!” “Goodbye.”

• “That’s not so big.” “Goodbye.”

What’s the effect of setting the main dish for tuesdayMenu on wednesdayMenu?

Var tuesdayMenu = DinnerMenu (mainDish: "veggie stew", sideDish" "bread", beverage: "fizzy water")

let wednesdayMenu = tuesdayMenu

tuesdayMenu.mainDish = "chicken parmesan"

• A. Wednesday’s main dish is now “chicken parmesan” because wednesdayMenu is a was assigned to be equal to tuesdayMenu.

• A. Wednesday’s main dish is now “veggie stew.” Because wednesdayMenu is a separate instance value from tuesdayMenu

• A. The code fails with an error because wednesdayMenu is a constant and cannot be changed.

• None of the above

Why does the code have the error “Use of unresolved identifier ‘isBelow’” on the marked line?

• isBelow should be declared before the if statement and value assigned inside

• There is a spelling mistake in the constant name

• The “let” statement should be “var”

• The line with the error should read:

  Return isBelow: Bool

What will this code snippet print out?

let number = 100

if number > 99 {

print ("what a large number !")

} else {

print ("That's not so big.")

}

print ("Goodbye.")

• "What a large number!"

• "What a large number!" "That's not so big"

• "That's not so big" "Goodbye."

• "What a large number!" "Goodbye."

Choose the code snippet that would produce the error:

Use of unresolved identifier ‘myFirstWord’

• let myFirstWord = "juice"

• var myFirstWord = "indubitably"

  myFirstWord = "dada"

• myFirstWord = "uh oh"

Choose the code snippet that would produce the error:

Cannot assign to value: ‘myFirstWord’ is a “let’ constant

• let myFirstWord = "juice"

  let myFirstWord = "banana"

• let myFirstWord = "bye"

  myFirstWord = 1

What caused the error in the second line of this code?

let guestList = ["Kusuma", "Mariana", "Tamsin"]

guestList [0] = "Monica"

• It’s trying to add a number to an array of strings.

• It’s trying to assign to the zeroth element, which doesn’t exist.

• It’s trying to modify a collection, but the collection is immutable.

• It’s trying to replace an existing element instead of appending.

What will this code snippet print out?

let number = 100

if number > 99 {

print ("what a large number !")

{ else if number < 150 {

print ("Goodbye.")

• “What a large number!”

• "What a large number!” “Goodbye.”

• “That’s not so big” “Goodbye.”

This function has a “type annotation missing in pattern” error on the highlighted line. Which option will fix the error?

func isBelow13 (number: Int) -> Bool {

var isBelow

if number < 13 {

isBelow = true

} else {

isBelow = false

}

return isBelow

}

• A. Bool var: isBelow

• A. var isBelow: Bool

• A. var isBelow Bool

• A. var Bool: isBelow
