Darryl has chosen to use scanf() to input a line of text. Why is this a bad decision?

Select an answer:

• The scanf() function cannot read strings.

• The scanf() function assigns values only to single variables and a string is a character array.

• It isn't: The scanf() function is more than capable of reading any string.

• The scanf() function stops reading text input at the first whitespace character.
