) ? i said wtf.., no I said what? can & be a default function provided by c+
+ for u to overwritten? he then said ok then we move on...

In C++03 there are 4:
*
Default constructor: Declared only if no user-defined constructor is
declared. Defined when used
*
Copy constructor - declared only if the user hasn't declared one.
Defined if used
*
Copy-assignment operator same as above
*
Destructor same as above
In C++0x there are two more:
* Move constructor
* Move-assignment operator
放狗查的，我记得也就那前面4个。
我记得有人argue过copy constructor 不算default function. |

发帖数: 1327 | 11 really? I can use "a > b" clause in my class function without overload ">"
operator, so as "&". so what is the difference between "&" and ">" here?
they are all given by default.
