Is the friend specifier within the class definition or within an inherited instantiation?

Its within the class definittion.. I just made a little reasearch and i found out that VC++ has a liitle bug when using namespace std; with friend functions.. Now i am trying to download the upgrate package and hopefully i will make it work.. Here is a link with a description about this "bug".. http://www.cs.virginia.edu/~csadmin/pc/pclabs/vc_faq/
just screw down and you will see.. also information on upgrading... Thanks ..

Dear Carl, Normally u won't get such an error. The friend keyword must me specified at the delaration inside the class, not at the definition. And also note that the friend function cannot access the private members of the base class if it is a friend of the derived class.

Ok ..maibe i was wrong when i said deffiniton...My program actually is quite simpe-i dont have derived classes..Its a just a simple class with three priavet data members-gpa,id,name..some functions and a a few friend functions as public within the class. I compiled with bloodshed and it wordked , but with VC++ it didnt work and i kept getting that error message that i dont have permission to access the data members.. But after i downloaded and upgraded from the link which i specified above it seems like it works.. I am pretty sure something was wrong with the microsoft compieler... But thanks to all of you..:-) Carl
