C/C++ would be good option to write some of the performance critical aspects of a Ruby Application. I know this is possible.
I would like to know how to add C/C++ code into Ruby code; any other language for that matter.
Are there any practical applications of this which you noticed in open source projects or else?

Besides "Extending Ruby", here are two other resources:
- README.EXT (extension.rdoc) - shows you more about how to build C extensions. A good compliment to "Extending Ruby"
- Ruby Inline - This is a library that tries to make it easier to build C extensions by having you call methods in ruby to compile C code.

Look in the "Extending Ruby" section of the Pickaxe book:
http://www.ruby-doc.org/docs/ProgrammingRuby/html/ext_ruby.html

you should have a look at SWIG - it allows you to create ruby extensions in C/C++.
回答4:
We use ffi in one of our projects.
Ruby-FFI is a ruby extension for programmatically loading dynamic libraries, binding functions within them, and calling those functions from Ruby code. Moreover, a Ruby-FFI extension works without changes on Ruby and JRuby.
It works quite well.

Compile your high performance code into a system service/executable, and call it from inside Ruby...?

Seems like you need to read up on Extending Ruby
