A string is an array of characters. Strings can represent words, sentences, or even whole books. In this section, we will cover how to perform the following string operations:

• How to get the length of a string
• How to concatenate two strings into a single new string
• The coercion of other types into strings
• String escape characters

Additionally, this section will cover how to read input from the console. You already know how to print information to the console; applications will become much more interactive once you can also read input from the console.
