Explain why it's false for the answers that are false.

TRUE/FALSE The size passed to operator new[] can be any integer valued expression - not just constants or literals like when dedaring a static array. TRUE / FALSE ~ has now been overloaded to be the destructor symbol. TRUE/FALSE You can call the destructor of object X by saying ~X. Fill in this (pseudo)code for an operator = method of a class named Class. TRUE / FALSE Overloading operators cannot change their -arity (their number of arguments). TRUE / FALSE As a consequence of this, we cannot use default arguments with operator functions. TRUE / FALSE Except, of course, for operator(), which has arbitrary -arity to begin with. Name at least two operators which, when overloaded, must be class member functions. (Reminder: there are four (4) operators that the standard requires to be member functions when overloaded.)

Explanation / Answer

1) False - we cannot pass any int expression as new size because constants are expected

2) True
   True

3)
public Class operator=(Class other)
{
   if(other!=other1)

   return other;
}

4) True
   True
   True

5) +,-,*,/ are the operators which when overloaded must be class member functions
