...calls

We don't regard parallelism here.

...it

Not all real languages provide such a type. In C this can be emulated with pointers.

...language

You might ask, why we should declare an Integer class if there is already an integer type available. We come back to this when we talk about inheritance.

...[2]

This book is only available in German. However, since this is one of the best books about object-oriented programming I know of, I decided to cite it here.

...point

We use lowercase letters when we talk at the object level.

...characters

Don't argue whether such a method makes really sense or not. It is just introduced for illustrating purposes.

...apples

Of course, there must be a definition for the type Apple.

...parenthesis

This is due to a historical ``accident'' while developing C .

...object

In the following we will drop the word ``object'' and will speak of ``the point''.

...languages

This is due to the fact that C++ supports function polymorphism. Therefore the name mangling must take function parameters into account.

...files)

This also creates an intermediary preprocessed raw C++ file. A typical suffix is .i.

...files

This has nothing to do with objects in the object-oriented sense.

...libraries

For example, standard functions such as printf() are provided this way.

...templates

C++ also allows the definition of function templates. However, as we do not use them, we will not explain them any further.

...lists

Do not mix up this use of ``class'' with the ``class definition'' used before. Here we mean with ``class'' a set of class definitions which share some common properties, or a ``class of classes''.
