Why use C in this tutorials?

• wide-spread low-level programming language
• trying to avoid monoculture
• C & C++ often used in mobile/real-time/multimedia applications

Differences C / Java

• no object-orientation
• direct memory access
• no garbage collection
• compiled code not platform-independent
• source code partially platform-independent (POSIX)
• no unified API
• low-level hardware/OS access

Open Source Code

• lots of existing source code on the net
• you may / should use existing code...
• ... but have to mention your sources
• watch the license

Acceptable licenses

• (GNU) GPL
• LGPL
• MIT license
• X license
• Public domain code
