| 10 | <para>These are the C compiler. A compiler translates source code in
|
|---|
| 11 | text format to a format that a computer understands. After a source code
|
|---|
| 12 | file is compiled into an object file, a linker will create an executable
|
|---|
| 13 | file from one or more of these compiler generated object files.</para></sect4>

|

| 26 | <para>cpp pre-processes a source file, such as including
|
|---|
| 27 | the contents of header files into the source file. It's a good idea to
|
|---|
| 28 | not do this manually to save a lot of time. Someone just inserts a line
|
|---|
| 29 | like #include <filename>. The preprocessor inserts the
|
|---|
| 30 | contents of that file into the source file. That's one of the things a
|
|---|
| 31 | preprocessor does.</para></sect4>

| 62 | <para>libstdc++ is the C++ library. It is used by C++ programs and contains
|
|---|
| 63 | functions that are frequently used in C++ programs. This way the
|
|---|
| 64 | programmer doesn't have to write certain functions (such as writing a
|
|---|
| 65 | string of text to the screen) from scratch every time he creates a
|
