What is overloading, overwriting, and overriding?

[shabbir]

What you mean by virtual destructor and what are the advantages of them??

[shabbir]

I always understood that in C++, if I said

a + b

a.operator+(b) is called.

Now this makes sense with the operator<< when used in the following way

cout << 100; // converts to cout.operator<<(100);

but then how does one explain this one

cout << end; // endl(cout).

In what order does C++ look for operator functions? What all functions does it search before giving up? In other words

when C++ sees

a+b

does it look for the existence of :

a.operator(b)
b(a)
a(b) ....???

or is the operator<< a special case?

[shabbir]

Is there any function(s) which cannot be overloaded?

[shabbir]

Should a Singleton class have a destructor and if it has what is the purpose of it?

Who do you expect to post the answers? or is it just the questions thread?

I had the plans of putting the questions only but if you wish to post the answers quote the message and put them as a post to the thread as well.

There is always an option of searching within the thread so that wont be a probs.
