|
|
|
|
<para>A compiler translates source code in text format to a format
|
|
that a computer understands. After a source code file is compiled into
|
|
an object file, a linker will create an executable file from one or more
|
|
of these compiler generated object files.</para>

<sect3><title>Preprocessor</title>
|
|
|
|
<para>A preprocessor pre-processes a source file, such as including
|
|
the contents of header files into the source file. It's a good idea to
|
|
not
|
|
do this manually to save a lot of time. Someone just inserts a line
|
|
like #include <filename>. The preprocessor inserts the
|
|
contents of that file into the source file. That's one of the things a
|
|
preprocessor does.</para>

<sect3><title>C++ Library</title>
|
|
|
|
<para>The C++ library is used by C++ programs. The C++ library contains
|
|
functions that are frequently used in C++ programs. This way the
|
|
programmer doesn't have to write certain functions (such as writing a
|
|
string of text to the screen) from scratch every time he creates a
|
|
program.</para>
