Maybe you will want this: data Person = Person { name :: String, age :: Int, favThing :: String } And get the age: getAge :: Person -> Int getAge p = age p Or better: getAge = age On 02/19/2015 11:28 AM, Roelof Wobben wrote:
Hello,
Im reading chapter 2 of the CIS 194 course about enumaratuin.
Now they give this example :
|-- Store a person's name, age, and favourite Thing. data Person = Person String Int Thing deriving Show
brent :: Person brent= Person "Brent" 31 SealingWax
stan :: Person stan= Person "Stan" 94 Cabbage
getAge :: Person -> Int getAge (Person _ a _)= a
I understand how this works.
But I wonder if there is no "better" way to get the Age.
Is it now wise to make a person data like this :
data Person = Name : String | Age : Integer | FavThing : String
And if so , how can I get the age then ?
