Why is this happening? How can I solve it?
If you take a careful look at this link, you will understand that you are trying to copy an ofstream object, and the copy constructor of ofstream is deleted. That is what the error is telling you. You could have simply searched for the error on Google though ;)

if(cout<<"h"){}
this gives me an output
h
Any idea why, I have tried many variations of it and it still works.
That's because the if statement needs to evaluate the condition you give into it, plus, streams are implicitly convertible to bool.

I am having problems in understanding this statement. I don't know why this is not usual like others.
Assignment means giving a new value to an already existing object. Even though const char INITIAL='G'; has an = sign, it is not an assignment, because it is creating a new object, not modifying an existing one. char INITIAL; INITIAL='G'; would be an assignment, because INITIAL already exists when the new value is, well, assigned.

I've tried searching for the answer, but nothing mentions stringstream specifically. I would guess that it would always work and you can always go back as far as the beginning of the underlying string.
Am I right?
How likely is istream::ungetc() to work with a stringbuf (as used in stringstream)?
Well, never.
There's no such thing like istream::ungetc() defined from the standard.
You can use either
int std::ungetc( int ch, std::FILE *stream )
or
std::basic_istream& std::basic_istream::unget()

All my attempts so far have failed.Basically when I return a copy of the internal char array of the string, that copy has to be released, but I don't know how to release it.Wrapping it in a smart pointer doesn't work out, since it's destructor gets called immediately after I return it.Must I implement something like a garbage collector just for the immutable string?
const std::string will be fine.
