This
chapter has given you a fairly thorough introduction to the iostream class
library. In all likelihood, it is all you need to create programs using
iostreams. (In later chapters you’ll see simple examples of adding
iostream functionality to your own classes.) However, you should be aware that
there are some additional features in iostreams that are not used often, but
which you can discover by looking at the iostream header files and by reading
your compiler’s documentation on iostreams.
