Outline

Part I

• Insertion sort on an array of integers: complete the program we started writing in class today for insertion sort on integer arrays (the incomplete model is posted here). Expand it to work also for an array of characters and an array of CustRec's.
  This program should be called sort.cpp.
• Insertion sort with templates and functions passed as parameters: modify the templated program we wrote for selection sort to implement insertion sort. The structure you want to use is started here. Test your program on arrays of integers, characters and CustRec, sorting both by id and balance.
  This program should be called sortTP.cpp.
• Test both programs and submit a single typescript for them, called typescript.

Part II

• Use the class notes for lecture 8. Copy, compile and execute the JarType files to make sure you know how to.
• Modify the JarType class to include new functions for removing cookies and testing the status of a cookie jar:
  • delete: takes in a number k, and removes k cookies from the jar.
  • IsEmpty: returns true or false, depending on whether the cookie jar is empty or not.
  • IsFull: returns true or false, depending on whether the jar is full or not. To do this part, you will have to add a new private variable maxNum in the description of the JarType. This variable will have to be initialized in the constructor, and will give the maximum capacity of the jar.
• Test these functions and prepare a typescript named typescript to show the execution of your program.

Part III

• Define a new class CookieJar, which will hold not just the number of cookies in the jar, but also keep track of their identity, in the order in which they've been added to the jar.
  • Technically speaking, you'll have to use an array to store the "cookies". Assume that each "cookie" is identified by an integer number (think of it as an id number, something like a bar code on a grocery item).
  • In the beginning, a jar is empty (i.e. the constructor initializes it to be empty).
  • The class should contain a function to add a cookie to the jar (takes in an integer, "stores" it in the array at the next position), and a function to "dispense" a cookie (returns the integer corresponding to the last cookie that was added).
  • Other functions you should include in your class are: IsEmpty, IsFull and Print (this function should just print the id's of the cookies stored in the jar).
• Test the new class using an appropriately designed test driver.
• Create a makefile for compiling the program for testing the CookieJar class, test it and save a typescript as typescript.

• Using submit Hw4I: sort.cpp, sortTP.cpp and typescript
• Using submit Hw4II: JarType.h, JarType.cpp, testJarType.cpp, makefile, typescript
• Using submit Hw4III: CookieJar.h, CookieJar.cpp, testCookieJar.cpp, makefile, typescript

Grading guidelines

• Part I and Part II, done perfectly, will get you a grade of B+.
• To get a grade in the A category, you must do Part III. A working program with static testing (i.e. similar to the one linked to from the lecture notes) is worth an A-. For an A, you must design a better (menu-based) test-driver, which will allow the user to choose which function to test next, among the available choices in the CookieJar class.
• A clarification: the menu-based testdriver should NOT have options for constructor(s). It should statically allocate a variable of CookieJar type, and apply on it the functions chosen by the user (via the menu-based interface)
