btw GCDEF you ever heard of a term called "friendship?"

wait lemme google it

Of course not. We're computer nerds. None of us actually has any friends, just public interfaces.

Besides, friends violate encapsulation.

This is a public programming forum. If you're just looking for a friend, perhaps Craigslist or match.com could hook you up.

sorry, but i'm not "just looking for a friend."

i just saw the guy is pretty new to C++ and wanted to be his friend because i like helping others.

if i was "just looking for a friend" I'd be hanging out with my peeps at this time.

Not according to Bjarne.

Surely just because it's explicit it doesn't mean that it doesn't violate it?

It was a bad joke based on a somewhat popular opinion. Hence the rolleyes smilie.

I'd like to see it that friend is there so you can "violate it" without "breaking it".

I have some protected interfaces reserved for future children.

It depends. If you believe that member functions violate encapsulation, then it is reasonable for you to believe that friends violate encapsulation. Otherwise, it is a matter of degree: friends reduce encapsulation.

My recommended online reading list related to this topic:
How Non-Member Functions Improve Encapsulation - Meyers
Designing Simple Interfaces - Stroustrup
Monoliths "Unstrung" - Sutter

Huh?

The most fun part of learning to program is figuring stuff out yourself. Try changing things in the program and see how it affects your results. Like try changing the numbers, changing cout << d to cout << a etc. See what happens, and you can probably figure that stuff out yourself.
