Quite some time ago I wrote a a small "C like" interpreter for
a the Zeus programmer's editor. It was developed using bison and 
flex (lexx and yacc clones). 

I would not say it is the most sophisticated language every 
written or the best interpreter every written, but it does 
work and it did the job for which it was designed. 

The ZIP package contains both the source code and a working EXE
file that was built using BC++ 5.0 compiler. The zip file can be
found at the following web page:

Just search for the ZMI and ZMPP links. The former is a C while
the later is a C++ versions of the interpreter .

The cost in this case is nothing but the time it takes for you 
to download it from the link above :)
