I believe there is an error in this video at about 7:30. '\n' and '\t' aren't string literals, they are escape sequences

See https://en.wikipedia.org/wiki/String_literal#Escape_sequences

Escape sequences are often used in string literals, and may be the sole component of a string literal, but it isn't really accurate to define them simply as such.

I believe that \t and \n are conscidered string literals because they actually add an ascii character to the string itself. As in \t adds a couple empty strings (spaces), and \n adds a new line character.

I may very well be wrong but, unless a mistake was actually made, I believe that this is a valid reasoning behind the statement.
