Exercise 1.2.2

More Strings

In Lisp, strings can contain any character without special markup, except for two particular characters which must be escaped; normally, what you type inside the double-quotes is exactly what you get. Line-breaks and all.

Sometimes though, you want to include double-quote characters inside your string. Lisp has a way of doing that, using the escape-character, \, the Backslash.

As it turns out, the backslash will escape any character. So if you want to print a literal backslash, it too has to be escaped.

* "this string contains \"double-quotes\"."
* "and this string has an escaped backslash: \\."

What You Should See

* "this string contains \"double-quotes\"."

"this string contains \"double-quotes\"."
* "and this string has an escaped backslash: \\."

"and this string has an escaped backslash: \\."

Once again, you get back exactly what you typed.
