How to get the first char from a string in Haskell

Overview

In this shot, we'll learn how to use Haskell to get the first character from a string. We can use the take function provided by Haskell to get the first character from a string.

Syntax

take n "provide string here"

Here, n denotes the number of characters to get. We provide n = 1 to get the first character from the given string.

Let's see an example:

Example

main::IO()
main = do
  -- get first character from a string
  print(take 1 "hello world")

Explanation

  • Line 5: We print the first character of the string using the function take and pass n as 1.
