Understanding these terms in C++, Friend, Operator and Ostream.

[JC0133]

How does these pre defined terms/functions work in C++.

Friend, Operator and Ostream.

What can you do or use these for?

 

[Exophase]

friend: A class that's a friend of another class can access its private and protected members (the opposite is not automatically true)
operator: A symbol that describes an operation. For example, "+" is the addition operator. Operators can be "overloaded" so that their operation is customized depending on what sort of things (operands) it's operating on.
ostream: Output stream. Used to output a sequence of data to something like a file or the screen.

That is usually interpreted a bit too narrowly to my liking.
Prime example: the "instructor" is self --> "no, this is not homework". Wrong. It is.

Herb Sutter's advice is to avoid having friends.

Operators are syntactic sugar, partly for the math fellows and partly to type less.

Many US military programs will not allow the use of the FRIEND in code delivered

That's one way of not getting distracted.
