Dear All.
Hope your 2016 is off to a great start.
I would like to get results from pattern matching or something.
Here is the my code.
data Person = Person {name :: String, age :: Int}
names = ["tom", "sara"] -- list of names, String
persons = [Person {name = "tom", age = 10}, Person {name="sara", age=9},
Person {name = "susan", age = 8}].
Is there any solution to get the age of "tom" and "sara"?
I have no idea of pattern matching for this one.
I've tried to use recursion, but I couldn't find any solution for list of
records.
Sincerely,
Young
