There are following files in gnuradio which can help me for adaptive filtering :
In the downloads folder there are following :
/Downloads/gnuradio/build/gr-filter/python/qa_adaptive_fir_filter_test.sh
/Downloads/gnuradio/gnuradio-core/src/lib/filter/gr_adaptive_fir_ccc.cc

In the installation folder there are following :
/usr/local/include/gnuradio/gr_adaptive_fir_ccc.h
/usr/local/include/gnuradio/gr_adaptive_fir_ccf.h
/usr/local/include/gnuradio/filter/adaptive_fir_ccc.h
/usr/local/include/gnuradio/filter/adaptive_fir_ccf.h
I asked in the gnuradio community regarding these two versions of the adaptive_fir_filter classes i.e. gr_adaptive_fir_ccc.cc & adaptive_fir_ccc.cc.
I got the reply as :
In many cases where we have functionality that we might want to use
other than as a GNU Radio block, we create an implementation class,
which we then create a gr_ class that wraps around this to bring the
implementation into an actual gr_block. So in this case, both are
valid, but one is a gr_block the other is the algorithm used inside of
the gr_block.

This means that gr_adaptive_fir_ccc makes the adaptive filter block while adaptive_fir_ccf_impl contains the implementational details of the same.
Lets look into them one by one :
Starting from gr_adaptive_fir_ccc.cc in /Downloads/gnuradio/gnuradio-core/src/lib/filter/ and its header gr_adaptive_fir_ccc.h in /usr/local/include/gnuradio/
Dependency graph for gr_adaptive_fir_ccc.h can be found at http://gnuradio.org/doc/doxygen/gr__adaptive__fir__ccc_8h.html
Dependency graph tells us what headers they include in a hierarchical manner.
Inside the header a class named "gr_adaptive_fir_ccc" has been declared
The class reference can be found at http://gnuradio.org/doc/doxygen/classgr__adaptive__fir__ccc.html#details
So it seems that this class is used in three examples :
digital_cma_equalizer_cc
digital_kurtotic_equalizer_cc
digital_lms_dd_equalizer_cc
