— This.


Yeah, I'm talking about copy ctor. Why doesn't it it get called when the call is from parameter of the friend function?

— Main also tries to copy, to pass an argument

— Actually, I want to ask that where does the copy constructor called from ? Inside the main?

— Yes, to create an argument. Then in fun to create nbj. Then move ctor is called to crrate an object being returned

— Can I say that cout is a stream?

— It is

— So, Just as cout is used as a stream between the program and the stdout, stringstream acts as stream between what 2 things?

— Program and string variable

— But isn't the string variable a part of the program?

— So? Not everything in program goes in cout

— Cout will copy the content of a variable into the stream and then the stream will feed it to the stdout

Can you describe stringstream in those terms for me?
