Appendix C. THE ASCII CHARACTER SET
Computers store characters using a numeric code. The ASCII code (American Standard Code for Information Interchange) is the most commonly used code in the United States. C++ lets you represent most single characters directly, by including the character in single quotation marks, as in 'A' for the A character. You can also represent a single character by using the octal or hex code preceded by a backslash; for example, '\012' and '\0xa' both represent the linefeed (LF) character. Such escape sequences can also be part of a string, as in "Hello,\012my dear".
