4.4    Built-In Data Types

So far you have only learned about types in a flyover—and around them, just as much fundamental C++ as was necessary to understand them.

This section builds on these basics. You now know enough about the language to understand the comprehensive explanations of all the built-in types.

In this section, you will learn which data types are available to you in C++ if you do not use #include in your program or do not use the standard library. What are the built-in data types, and what can you do with them?
