Chapter 13 Exercise Set 2: It’s War!

We will be modifying the Card objects we created in the Vectors of objects chapter, using the same Cards.h and Cards.cpp files. The new Deck objects will be added there too.

  1. Rewrite the find_card function from Searching as a Deck member function that has a Card parameter.

  2. Add a series of tests to test_random.cpp that evaluate the simulation of a roll of 6 sided die.

  3. Add a modifier member function to the Deck structure named swap_cards that takes integers as arguments (the indices of the two cards) and swaps the cards at these indices.

  4. Add a member function to the Deck structure with prototype:

    int find_lowest_between(int low, int hight);

    that returns the index of the lowest card in the deck between index low and index high inclusive.

  5. Add a modifier member function to the Deck structure named sort that uses the selection sort algorithm sketched out in the Sorting section to put the deck’s cards into sorted order.

  6. Complete the merge function sketched out in the Merge sort section. Then use it to complete the first version of merge_sort described in the section.
