C++ uses small integers internally to represent each different character. The set of characters a computer uses and the corresponding integer representations for those characters are called that computer’s character set. You can print a character by enclosing that char- acter in single quotes, as with cout << 'A'; // print an uppercase A You can print the integer equivalent of a character using static_cast as follows: cout << static_cast< int >( 'A' ); // print 'A' as an integer
