Constructor can not be virtual.becoz constuctor is an entity
which initializes the V-table(V-table stores the addresses
of all virtual member functions of a class.)So if we declare
a constructor as virtual then who will inialize V-table for
this constructor??Thats why constructor can never be virual.

Answer / john

virtual constructor is not possible.
This is because v-table is created only after the
constructor is called.

Definition of priority queue was given. We have to implement the priority queue using array of pointers with the priorities given in the range 1..n. The array could be accessed using the variable top. The list corresponding to the array elements contains the items having the priority as the array index. Adding an item would require changing the value of top if it has higher priority than top. Extracting an item would require deleting the first element from the corresponding queue. The following class was given: class PriorityQueue { int *Data[100]; int top; public: void put(int item, int priority); // inserts the item with the given priority. int get(int priority); // extract the element with the given priority. int count(); // returns the total elements in the priority queue. int isEmpty(); // check whether the priority queue is empty or not. }; We had to implement all these class functions.
