Write a function to calculate a tip of 20%.
Note: The simple way to do this is:
This is called a cast operation. When the preceding statement executes, it prints the value 65 (on systems that use the ASCII character set). Write a program that prints the integer equivalent of a character typed at the keyboard. Store the input in a variable of type char. Test your program several times using uppercase letters, lowercase letters, dig- its and special characters (like $).
Here is a peek ahead. In this chapter you learned about integers and the type int. C++ can also represent uppercase letters, lowercase letters and a consider- able variety of special symbols. 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
