Introduction3Hi mom!In addition, code listings appear as follows:// some programvoid main(){...}If you are entering these programs by hand, you must enter the text exactlyas shown with one exception: The number of spaces is not critical, so don’tworry if you enter one too many or one too few spaces.C++ words are usually based on English words with similar meanings. This canmake reading a sentence containing both English and C++ difficult to make outwithout a little help. To help out, C++ commands and function names appearin a different font like this. In addition, function names are always followedby an open and closed parenthesis like myFavoriteFunction(). The argumentsto the function are left off except when there’s a specific need to makethem easier to read. It’s a lot easier to say: “this is myFavoriteFunction()”than “this is myFavoriteFunction(int, float).”Sometimes, the book directs you to use specific keyboard commands. For example,when the text instructs you to press Ctrl+C, it means that you should holddown the Ctrl key while pressing the C key and then release both together.Don’t type the plus sign.Sometimes, I’ll tell you to use menu commands, such as File➪Open. This notationmeans to use the keyboard or mouse to open the File menu and thenchoose the Open option. Finally, both Dev-C++ and Visual Studio.NET definefunction keys for certain common operations — unfortunately, they don’tuse the same function keys. To avoid confusion, I rarely use function keys inthe book — I couldn’t have kept the two straight anyway.How This Book Is OrganizedEach new feature is introduced by answering the following three questions: What is this new feature? Why was it introduced into the language? How does it work?
