Comparing and manipulating structures
C++, being a computer language and all, provides you with a lot of ways to manipulate data — numbers, letters, strings, arrays — anything you can store inside the computer memory. To get the most out of C++, you should know as much as you can about the fundamental data types. This chapter covers them and how to use them.
In this chapter, we refer to the ANSI standard of C++. ANSI is the American National Standards Institute. The information we provide in this chapter deals with the ANSI standard (singular) of C++. Fortunately, the GNU gcc compiler that comes with Code::Blocks is ANSI-standard-compliant. (Little nuances show up, but not often.)
In the sections that follow, we tell you how you can manipulate your data, discuss the types of data available to you, and point out how you can change them.
The ANSI C++ standard dictates these fundamental C++ types: ...
