26. What is the output of this program?
    

    #include <iostream>
        #include <cmath>
        #include <list>
        using namespace std;
        bool IntegralPart(double One, double Two)
        {  
            return ( int(One) == int(Two) ); 
        }
        struct is_near 
        {
            bool operator() (double One, double Two)
            { 
                return (fabs(One - Two) < 5.0); 
            }
        };
        int main ()
        {
            double Array[] = { 10.05, 3.70, 12.02,  10.25,  14.24, 11.47, 76.32, 82.35, 95.31, 52.95 };
            list<double> ListData(Array, Array + 8);
            ListData.sort();
            ListData.unique();
            ListData.unique (IntegralPart);
            ListData.unique (is_near());
            for (list<double> :: iterator iter = ListData.begin(); iter != ListData.end(); ++iter)
                cout << ' ' << *iter;
            cout << '\n';
            return 0;
        }

   NA

   Correct Option: D

   In this program, We are eliminating the values by using the unique operation in the list.

27. How the list containers are implemented?

1. 1. Using Single linked list

   
   
   

   2. Using Double linked list

   
   
   

   3. Using Single & Double linked list

   
   
   

   4. All of above

   
   
   

   5. None of these

   NA

   Correct Option: B

   List containers are implemented as doubly-linked lists. Doubly linked lists can store each of the elements they contain in different and unrelated storage locations.

1. 1. List

   
   
   

   2. Dequeue

   
   
   

   3. Array

   
   
   

   4. Vector

   
   
   

   5. None of these

   NA

   Correct Option: C

   Because array is not dynamic in nature, So they can’t be manipulated.

29. What do container adapter provide to interface?

1. 1. No interface

   
   
   

   2. Restricted interface

   
   
   

   3. More interface

   
   
   

   4. All of above

   
   
   

   5. None of these

   NA

   Correct Option: B

   A container adapter provides a restricted interface to a container.In particular, adapters do not provide iterators; they are intended to be used only through their specialized interfaces.

   2. int

   
   
   

   3. any type of object

   
   
   

   4. double
