52.  def readLine: IO[String]

    Reads a line as a string from the standard input using the platform's default charset, as per java.nio.charset.Charset.defaultCharset().

    Reads a line as a string from the standard input using the platform's default charset, as per java.nio.charset.Charset.defaultCharset().

    The effect can raise a java.io.EOFException if no input has been consumed before the EOF is observed. This should never happen with the standard input, unless it has been replaced with a finite java.io.InputStream through java.lang.System#setIn or similar.

    returns

    an IO effect that describes reading the user's input from the standard input as a string
