Programming Assignments for Math 218
Make sure you save your programs in your folder in P drive for each lab before the deadline. Having it elsewhere (e.g. in your H drive) does not help. Do NOT modify after the deadline.
Assignment 6: Due 11:59 pm Friday Feb 27 (right before the spring break)
Do programming exercise 18 at the end of chapter 6, i.e. complete the program to solve sudoku puzzles. Your program should take the input from a file. Let the user enter a file name. You can assume that the file is in the same folder as your program. Do not require the user enter the puzzle. For output, send it to both the screen and to a file. Ask for the name of the output file from the user as well.
You can assume that the file you read the input from has the right format, i.e. 81 integer values between 0-9 with 0's indicating blank spaces. Test your program with a couple of sample input files (but it should be able to read from any input file specified). Note that the description of the findEmptyGridSlot function given by the textbook (and source code) is misleading. Please pay attention to the revision provided by your instructor.
Assignment 5, Due 11:59 pm, Thu Feb 19
Do the programming Exercises 2,3, 6 and 17 at the end of chapter 5. Use a single test program for all functions. You can use the source code of the textbook but with care. If you decide to terminate the program due to the violation of a condition (e.g, position entered is larger than the size of the list
) make sure that you pause the program before exiting for the user see the error message.
Note: As given, the source code from the textbook did not compile in our compiler. One solution is when the classes (such orderedLinkedList and unorderedLinkedList) inherit from the base class linkedListType<Type> specify the type like so:
class orderedLinkedList: public linkedListType<int> as opposed to more general class orderedLinkedList: public linkedListType<Type>
This is perhaps not the best solution (this was not a problem in the older versions of the compiler). If you can find a better solution, let us know!
Assignment 4: Due 11:59 pm, Tue Feb 10
Do programming exercises 3, 4, 5, and 6 at the end of chapter 4. Write a single test program for all of these tasks but make sure you test each function/task separately and fully, and provide the user a good interface (that should include the option of repeating computations). Some hints:
template < class elemType>
void reverseVector(vector<elemType> &list)
typename vector<elemType> : : iterator Itr1,Itr2;
..... FILL IN THE REST
Bonus: Do exercise 10 (stock market) at the end of chapter 4. You have until the end of the spring break to do this one (11:59 pm, Tue March 17). If you decide to do this exercise make a folder titled "Bonus" and put it in there. You can use the file "StockData.txt" inside the folder "FilesForLabs" for initial testing, but it would be better to use a bigger/more realistic data.
Assignment 3: Due 11:59 pm, Tue Feb 3 (extended by 24 hours)
Part I: Do programming exercises 1-4 in chapter 3 (page 204-5). Write a single test program to test the functions you write. You may use the source code provided (with care).
Part II: Do programming exercise 8 (page 205). Also include the ~ operator to compute the derivative of a polynomial (see exercise 7). Write a single test program to test the functions you write. You may use the source code provided (with care) but do not assume that the source code from the textbook has the best test options. For example, you should let the user evaluate a polynomial at any complex value, not just 5.
Assignment 2: Due 11:59 pm, Tue Jan 27 (This lab is also a review from the first programming course)
Part I: is on inheritance and described here
Part II: In Programming Example of section 2, Complex numbers are implemented. Extend the definition of the class complexType given in the book by overloading the following operators:
- : for subtraction
/ : for division
~ : complex conjugation
! : absolute value
(See exercises 12-15 for more detailed description). Notice that - and / are binary operators whereas ~ and ! are unary operators.
Implement - and / as non-member operators but ~ and ! as member operators. Use the pointer this in the implementations of ~ .
You may use the files given in the book, but make sure you modify the test program so that you throughly test the new operations you define.
Part III: (For practice, not for grade) Do programming project 4 on page 125 in 2 ways: First using inheritence as described in the book. Second using composition where the class circleType includes the class pointType. You may use the test program in the class folder FILESFORLABS\Lab2 (for the inheritance version), or you can write a test program similar to it.
Assignment 1: Due 11:59 pm, Tue Jan 20 (This is a review from the first programming course)
Do programming exercises 1 and 6 at the end of chapter 1. Writing a reasonable test program with good user interface (e.g. letting the user repeat the computation) is an important part of the assignment (and this is a default requirement in all future assignments as well. This course is also about "program design"). For exercise 1, you can assume that the input for Roman numeral is a legal string. Your program should allow the user to enter/test more Roman numerals than given in the text.
Also, write up solutions for problems 6-8 in the worksheet "Practice with Big-O Notation" and turn them in class on Tuesday, Jan 20.
