[ns] Debugging ns code (.cc files) with print statements

[Ns Learner]

Hello,

I am trying to debug ns code (.cc files) with print or cout statements.

With cout, I get this error message:

error: ISO C++ forbids declaration of ‘cout’ with no type
error: expected ‘;’ before ‘<<’ token


I tried inserting using namespace std and it still gives me an error message.
Print or printf statements simply do not print message on to my console.

Can somebody help?

Thanks :D
