finds the largest number in the array. You can not sort
array or use any API or searching needs?
You attempt to query the data base with this command:
SELECT name, salary FROM employee WHERE salary=(SELECT
salary FROM employee WHERE last name='Wagner' OR dept no=233)
Choose most appropriate option from the following:
1)Sub-queries are not allowed in the where clause.
2)a multiple row sub-query used with a single row comparison
operator.
3)a single row query is used with a multiple row comparison

ex: COND((4,GE),EVEN).what the comma mean here. is
that 'and' or 'or'.

Question In a class, there is a reference or pointer of an
object of
another class embedded, and the memory is either allocated
or assigned to the new object created for this class. In
the constructor, parameters are passed to initialize the
data members and the embedded object reference to get
inialized. What measures or design change should be advised
for proper destruction and avioding memory leaks, getting
pointers dangling for the embedded object memory
allocation? Please suggest.

There is something to be taken care in destructor, in copy
constructor, suppose the memory is assigned to the embedded
member object pointer with the parameter passed value, but
if some other objects of different class also are pointing
to this memory, then if some one deletes the object then
this class member pointer object will become dangling, or
if the object is not deleted properly then there will be
memory leak. Please suggest the design change required to
handle or avoid this situation
