[ns] printing variable in C++

[Mahesh <mahesh@cs.iitm.ernet.in>]

Hi seniors,
	I was twikling the code of compute_routes() function in route.cc
file since a couple of days. I'm not able to see the values of the
variables (hopcnt(), ROUTE(), ROUTE_ENTRY()), whatever i print, they are
shown as zeros. I felt that a variable in C++ can't be printed directly.
If that is true, How to print them?

Thanks in Advance,

Regards,
Mahesh.
