Here are the topics for the third exam.  Once again, you may bring one 8.5 by 11 inch piece of paper with notes.
Make sure you have studied the example restaurant program that can be found on the examples page.

Office hours:
Monday, April 28, 12-1
Tuesday, April 29, 1;15-2:15
Wednesday, April 30, 11-12
Thursday, May 1, 12-1 (NOT 1:15-2:15)
Friday, May 2, 2-3
Monday, May 3, 11-12

On the examples page I put up the program that will be on the final.  Copy it. Print it. Run it. Discuss it.

April 22, midnight
The final exam is on Thursday, May 1, not Monday.  The room has not yet been set.

April 22, 10:00 pm
In order to make both HW pages agree, I have set the final project due date as Tuesday, May 6.

April 3, 10:45 am
I have made some slight modifications to hw6.  Please see the hw6 page and make sure you see the note in red at the top of the page.

March 25, 4:45 pm
There is a typo in the homework.  In part c when I talk of the Book class I really mean the Medication class!  (The error has been fixed on the hw page.)

To read in the file name for hw5 you have a few choices.
The constructor ifstream myfile(file_name);
expects an old fashioned c-string, that is, an array of char.
One choice is to use an array of char, use cin>>that_array_name and then pass that_array_name to the ifstream constructor.
The other choice is to use a C++ string, and pass to the ifstream constructor the underlying c-string which you can get using the function
s.c_str()
where s is the string.  [Think, some member data of C++ string is an array of char, and c_str() is the "get" function that returns that array of char.]

There will be no class on Thursday, April 17.

Topics for exam 2
Also recall that hw 5 is due on March 27, not the 25th.

March 18, 4:15 pm
On the examples page I put up a sheet that talks about strings (C++ strings, not C strings)  You will need getline to read white space from the file.

Here is a Rationals class header and implimentation that you may use in assignment 4.  You may use your own version of the class, or put together a new combined version. If you use your own class you will need to modify the input and output to accomodate files.  I present the member functions
istream& Rational::read(istream & infile);
ostream& Rational::printquotient(ostream & outfile);
ostream& Rational::printdecimal(ostream & outfile);

As an example, in the program I wrote to create the file your program will use for input, I had the code

    ofstream myout("problems2.txt");
    Rational r,s;
         //code that sets values for r and s
    r.printquotient(myout);
    myout << ' ' << pickanop() << ' ';  //pickanop() is a function that returns a char +, -, *, or /
    s.printquotient(myout);
    myout << endl;

You may want something like this when teaching the computer how to output an equation.
You will not want something like this in your main, because by then the computer will already know how to output a whole equation.

You may find the class even easier to use if you change these i/o functions to non-member friend functions
istream& operator>>(istream & infile, Rational r);
ostream& operator<<(ostream & outfile, Rational r);  //for printquotient.  This assignment doesn't use printdecimal.

If you like, you may change the read and print functions for the Equation class into friend operator functions.

Another note:
You may assume that the file of equations has no more than 100 equations.

The parameter of the set function should be changed from op to oper so as not to conflict with the name of the local variable.

I have put up a sample file for fractiondata.txt.  A link has been added to the hw4 page.

February 25, 10:30 pm
Some comments on HW 4.

theOps and Operation:
What you will be storing as member data is an integer for the operation.  The only integers it can be are 0, 1, 2, and 3 because we have created a special "type" called Operation.  When it comes time to print out an equation, you don't want to print 1 for minus, you want to print -.  You will notice that, if you rig it as suggested, theOps[minus] is the symbol -.  For the time being, make theOps ordinary member data - remove the work static.  We will discuss static next class.

withAnswer:
For the time being remove static from the description of withAnswer.  You can make it static once we discuss static.  The print function looks at the value of withAnswer to know if it should be printing with answers or without answers.

patch for VC++
If you have succeeded in applying the patch, let me know which patch and how you installed it.  Some others have questions or problems.
 

February 25, 8:00 pm

If you are getting an error that says >> ambiguous or something like that, you may have a problem with the VC++ bug for friends in namespace std.
Easy get around:
#include<iostream.h> instead of
#include<iostream>
and get rid of
using namespace std;
(You have to use .h for all your header files)

Long term solution:
Go to Microsoft's web site and install the patch.

February 12, 7:15 pm
The sections refered to on the Topics page are from the 3rd edition of Deitel and Deitel.

February 10, 10:30 pm
There is a new proceedure for submitting homework.  You create your project and zip it exactly as you did before.  Now go to
https://www.ecs.syr.edu/faculty/baruch/upload.cfm
You will be asked for your ecs user name and your NT password.  (You must have one.  Go to the cit office and get one if you don't have one.)  Follow the instructions for uploading the file.

The old homework account will be gone.  Send e-mail directly to Dr. Baruch or Prateek if you have questions to ask.

February 6, 9:30 pm
Topics for exam 1.
The exam is closed book, but you may bring an 8.5 in x 11 in piece of paper with anything you like on it.
You may bring a foreign language dictionary, but you may not share dictionaries.
Bring pencils, pens, erasers, ... You may not share during the exam.
On the exam there may be

• programs to write
• code segments to write.  By a code segment I mean you do not need to write an entire function, just a few lines of code to accomplish the task.  For example, if I ask for a code segment to create two integers, read values into them, and print their sum, I would expect something like

int a, b;
cout << "Please enter two integers:";  
cin >> a >> b;
cout << "Their sum is " << a+b << endl;

• programs for which you must give the output
• short answer questions
• multiple choice where you should circle all valid answers
• true/false question.

February 6, 8:30 pm
How did I get that answer! Sorry for the error.
318/234=53/39, not whatever I had on the page before.
318/6=53  234/6=39.

January 30, 10:15 am
The homework (hw 2) has been modified to have the user choose the number of candies in each row.  Make sure you have a copy of the updated assignment.

January 14, 11:00 pm
Prateeks e-mail on the syllabus page has been changed.  Please note the new address.  Also his office hours have been posted.
