Friend void friend templatename (classname astric const prt
classname);
}
CS304
Question No: 28 ( M a r k s: 2 )
State
any two reasons why the virtual methods can not be static?
1-virtual method can not be static as it is dynamic
2-as virtual method is dynamic so it works automatically
that is also another reason
That virtual method can not be static.
CS304
Question No: 29 ( M a r k s: 2 )
Explain
the statement below,
vector
ivec(4, 3);
CS304
Question No: 30 ( M a r k s: 2 )
Explain
two benefits of setter functions.
1-
It minimize the changes to move the objects in inconsistent
states
2- You
can write checks in your setter functions to check the validity of data entered
by the user, for example age functions to check to calculate the age from date
entered.
CS304
Question No: 31 ( M a r k s: 3 )
Consider
the code below,
template
class
T1 {
public:
T i;
protected:
T j;
private:
T k;
friend void Test();
};
This
code has a template class T1 with three members i,j and k and a
friend function Test(), you have to describe which member/s of T1
will be available in function Test().
public:
T i;
protected:
T j;
CS304
Question No: 32 ( M a r k s: 3 )
What
do you mean by Stack unwinding?
When we want to check what happens actually to the local
variables in the try block when then an exception is thrown this concept is
called stack unwinding.
CS304

What
is random_iterator? What is relation between random_iterator and Vector?
Random_iterator: it provided both increment and decrement
and also provide constant time methods for moving forward and backword in
arbitrary sized steps. Ramdom iterator provide asentially all of the operations
of ordinary c pointer arithmetic.
Vector class provide an stl style random access iterator for
use with generic algorithm since neither the vactor nor the matrix classes are
container classes in actuall. The iterator class is really an iterator of data
object that is viewed by vector or matrix.
