Question

In the following questions you will be designing a class called SuperDraw to

generate lotto numbers and manage the process of verifying whether a ticket

is a winner. Every lotto ticket has 6 numbers generated randomly between 1

and 49. A number cannot be repeated in the same ticket.

The main SuperDraw class structure should look like the following:

struct ticket

{

unsigned int numbers[6];

ticket* next;

};

class SuperDraw

{

private:

ticket* ticketListHead;

ticket* ticketListTail;

public:

SuperDraw(/* args */);

~SuperDraw();

};

ticket

is a linked list structure that holds the 6 lotto numbers in an array and a pointer to

the next element in the list. Notice that the class SuperDraw has 2 private data members,

ticketListHead and ticketListTail. They are 2 pointers pointing to the head (first element)

and the tail (last element) of the linked list.

Question 1 (5 pts)

Complete the implementation for the class SuperDraw by implementing the constructor

and the destructor bodies if needed. Constructor should be initializing the object to

whatever initial suitable state.

Question 2 (15 pts)

Add a public method called newTicket(int verbose = 0) that generates random 6 numbers.

The newly created ticket should be added to the linked list and the randomly generated

numbers should be printed out to the screen if verbose argument is set to 1. By default the

verbose argument is set to 0 which means that no messages will be printed out to the

screen.

The numbers should be sorted in ascending order.

Remember that the pointers ticketListHead and ticketListTail should be updated

accordingly after the generation of each new ticket

The test main() function should look like the following:

int main()

{

SuperDraw sd;

sd.newTicket(1);

}

The output should be something like:

A new ticket was successfully generated. The numbers are: 12, 14, 23, 39, 40, 44

Add a constructor that takes an int argument which corresponds to the number of tickets

to be generated.

Question 3 (10 pts)

The test main() function should look like the following:

int main()

{

SuperDraw sd(2);

}

The output should be something like:

2 new ticket were successfully generated.

The numbers are: 12, 14, 23, 39, 40, 44 and 1, 2, 9, 12, 28, 41
