Test: Swift - Forced Unwrapping of Optionals

5. var totalScore = 100 - what’s the type of totalScore variable in Swift?



Results
Congratulations! Correct Answer.
You Answered: None. If you took the test, your answer will show up here.
Correct Answer: Int
Explanation
Swift infers the type of the variable by looking at the assigned value during initialization. Here 100 is an integer literal. And hence the type would be Int. I will not be an optional Int (i.e. not Int?) and assigning a nil value to totalScore after the above declaration will be an error.
