To ask Edu how he is doing in Swift, you can declare a function that takes in Edu's name as a parameter and outputs a message to the console. Here's some sample code that demonstrates this:
main.swift244 chars11 lines
In this code, we declare a function called askHowEduIsDoing
that takes in an optional string parameter name
. We then use optional binding to unwrap the name
parameter and assign it to the constant eduName
. If name
is nil
, we output an error message to the console.
Assuming we provide Eduardo
as the name
parameter, this code will output the following message to the console:
main.swift41 chars2 lines
