Haskell - Assigning a value to user defined types

Question

Question

I have defined a user defined type as

type asd = [(Char,Int)]

How can i assigin a value to a type asd such as asd= [("Hello",1)] (Not in run time) to keep hard code a value in source code

is this possible ? , becouse there is no variable concept in functional programming

Answer 1

You are defining a constant. An example would be:

-- A type of lists of pairs
type ASD = [(String,Int)]

-- A value of type ASD
asd :: ASD
asd = [("Hello", 1)]

That is, you just declare what the value of asd is.
