WebMay 20, 2024 · The ‘..’. Syntax in the expression [‘A’..’Z’] works on any type which is a member of the ‘Enum’ type class, which is to say it has some type of successor/predecessor order. A comes after b, c comes after b and so on. So typing [‘A’..’Z’] just creates a literal list of the characters from ‘A’ to ‘Z’. Come to think ... Weblines “your string separated by newline character.” 6. unlines. This function does opposite of lines function in Haskell, it will join the string and return us the string object. Return type for this function is string value after joining. Also it will append \n or we can say a newline character after each string as result. Use:
