get first char from string haskell
To get the first character from a string in Haskell, you can use the head
function. The head
function returns the first element of a list, so you can treat the string as a list of characters and use head
to get the first character. Here's an example:
getFirstChar :: String -> Char
getFirstChar str = head str
In this example, the getFirstChar
function takes a String
as input and returns a Char
. It simply calls the head
function on the input string to get the first character. You can use this function to get the first character from any string in Haskell.
