That's because the backslash character, is the escape character and when
we use it on it's own, we get an error message.
As it expects,
something follows it. Another useful sequence, is the single
quote sequence, for when you want to include a single quote, within our string.
For example, if I want to say, don\'t, then I use backslash,
quote, for the place where I'd like the single quote to occur and similarly,
when I want to use a quotation marks, double quotation marks
in a string, I can use the escape sequence, backslash, double quotes.
So, imagine that we want to do this, says, He says.
[SOUND]
and I use \ double quotes to indicate that I
would like to use the double quote in the string
