Should b not be let?

Question

Variable b should be made a constant since it never changes

Hence

let b = value

Alternatively the answer should accept both let and var in the declaration of b.

Answer 1

in what context?! 😅😅

Answer 2

did the question not attach the quiz?

Answer 3

The question asked something similar to

Answer 4

swift

Answer 5

var a = 10
__ b = 30
let sum = a + b
print(sum)

Answer 6

the question asked to fill in the blank but wouldnt accept let as an answer

Answer 7

If that was your only code, your version would work since 30 is the only number b is. However, this code is meant to be reusable as you will see if you continue in Swift. Other parts of the program would be able to change "b" and return a different sum (the whole point in using variables). B should be a var. Otherwise you may as well just type: print(10 + 30) or even just print(40)
