Hi Pradeep, welcome!
If by programming you mean how do you get a particular fpga
configuration loaded into the fpga, the host side library loads either
the default or the specific ".rbf" file named in the constructor of
usrp.source_c and usrp.sink_c. This happens over the USB.
If you want to know who to build custom FPGA bitstreams, then it's best
to start with existing top level code in
usrp/fpga/toplevel/usrp_std/usrp_std.v and go from there.
You can find brief directions on building the existing code in
usrp/README
I hope this helped!
