Subject: [Dev-C++] student needs a little help



Hello Everyone,

I'm currently a CS Student and need a little help. I have been given the
enclosed programming assignment but I'm not sure how to do it. It seems
like a simple problem to solve but I don't know how to do list let and
from the looks of the problem it will need one. I guess the teacher
things we are supposed to know how to do list already.

Anyhow, I'd like a few pointers on how to do this problem if possible.
Maybe how to do the part of the code where it would require a list and
search.

Any help is appreciated, thanks. 

 

Except of the fact that you can use the ready C++ list in <list> header
file, you can use an array too. In fact i do not see why you shoud use
any container at all.

Program #2:   Grocery Store Checkout    (60 points)

 

Your assignment is to write, run, and test a C++ program, pg2, to
simulate the operation of a

grocery store checkout system. Your program should first build a data
structure to contain

information on all the products available in the store. Then the program
should print the cash 

register receipt for each customer. 

 

 

A data structure example:

 

class product

{

 unsigned product_number;

 std::string description;

 unsigned price;

 unsigned tax;

 

 public:

product(const unsigned &pn, const std::string &desc, const unsigned &pr,
const unsigned &tx): product_number(pn), description(desc), price(pr),
tax(tx) {}

 const unsigned &get_product_number() const { return product_number; }

const std::string &get_desc() const { return description; }

const unsigned &get_price() const  { return price; }

const unsigned &get_tax() const { return tax; }

void set_product_number(const unsigned &pr) { product_number=pr; }

void set_desc() { description=desc; }

// ...

};

 

 

 

 

INPUT

The input for pg2 has two sources: the inventory information is input
from a text file, 

and the customer transactions are input from the keyboard.

 

1. The information about each product carried by the store is listed on
a single line in the

    inventory file "invent.dat", in the following format:

                        <product number> <description> <price> <tax>

    where <product number> is a five-digit positive (nonzero) integer,
<description> is a string of 

    at most 12 characters with no embedded blanks, <price> is a real
number, and <tax> is a 

    character ('T' if the product is taxable; 'N' if it is not taxable).
The data in the inventory file is 

    ordered from smallest to largest product number. 

 

For every element you will do checking to see if the arguments comply
with these rules and then you will throw an exception for everyone it
doesn't. You will create an exception inheritance like this:

 

class general_exception

{

 unsigned exc_id;

 public:

general_exception(const unsigned int &id): exc_id(id) {}

 virtual operator unsigned() { return exc_id; }

 virtual ~general_exception {}

 virtual const std::string & message() const=0;

};

 

class desc_exception: public general_exception

{

 std::string msg;

// ...

};

 

 

Or something that fits you better.

 

 

 

 

 

2. The customer transactions are input from the keyboard, in the
following format:

                        <product number> <times>

    where <product number> is as described above, and <times> is an
integer in the range 1 to 100, 

    indicating the quantity of this product desired. A zero input for
<product number> indicates the 

    end of the customer's order. (The store will soon be using a scanner
to input the product number, 

    but for now it is typed in by the cashier.)  

 

You will throw exceptions in case of errors.

 

 

OUTPUT

 

The program outputs should be written to a text file called
"receipts.out", which can be printed

out for purposes of determining your grade. 

 

1. The inventory information of invent.dat is echo printed to the output
file. 

 

2. The cash register receipt for each customer is written to the output
file. The receipts should be 

    nicely formatted, with the product description (not the product
number), number of items, item 

    price, and total price for each product printed on a single line. At
the end of each customer's 

    order, the subtotal for all items, amount of tax on taxable items,
and total bill should be printed, 

    clearly labeled. (The tax rate is 7.5% for taxable items.) 

 

PROCESSING

 

pg2 first reads in all of the inventory information from file
invent.dat, echo printing the 

information to the output file receipts.out. The program then prompts
the cashier to begin inputting 

the order for the first customer. This customer's order is processed,
and the receipt is printed to the 

output file.

After each customer's order is processed, the program should ask the
cashier if another customer is 

to be processed. If the answer is 'Y', the program sets up to process
the next customer; if the answer 

is 'N', the program terminates with a friendly message. 

 

ERROR CHECKING

 

The following input errors are possible and should be handled by pg2

 

1. Duplicate <product number> in inventory file. Write an error message
to the output file and skip 

    the second entry. 

2. <Product number> not in inventory file. Write an error message on the
receipt, ignore that product 

    number, and continue with the next item. 

3. <Times> not in the specified range. Write an error message to the
output file, ignore that line, and 

    continue with the next item. 

 

EXAMPLE

 

  



.   From File "Invent.in":

     11012     gallon-milk        1.99      N

     11014     butter             2.59      N

     11110     pie-shells         0.99      N

     20115     laundry-soap       3.60      T

     30005     homestyle-br   0.99     N

.   From keyboard (one customer):

     11110  2

     40012  3

     20115  1

     0

 

.   To "Receipts.out" file:

---------------------------------------------------------

SEP 10, 1998 6:00 pm (* date and time optional *)

Customer 1

pie-shells        2  @  0.99  1.98

*** item 40012 not in inventory ***

laundry-soap  1  @  3.60  3.60 TX

     Subtotal  5.58

     Tax         0.27

 

     Total       5.85 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

DATA STRUCTURE

 

The inventory information can be stored in a list of product records.
Assume that the maximum 

number of products is 50, for purposes of writing this program. As the
data in the inventory file 

is ordered from smallest to largest product number, it is very simple to
insert the product records 

into this data structure in order. You can use either a sequential or
binary search to locate a product 

number in the inventory.

You should specify this data structure as an ADT, as described in the
chapter; define and implement 

a set of operations to encapsulate it. 

 

 

TEST PLAN

 

Be sure to include test cases to test your error conditions in your test
plan. 

 

DELIVERABLES

 

1. A disk of the source code of the program pg2 and all included files. 

2. Hard copy of a listing of your implemented test plan.

3. Hard copy of the output file, "receipts.out", produced by running
your program using the input 

    specified in your test plan.

 

For sorting and deleted the elements you will place another field in the
class like bool erased; which you will mark as true when you delete a
record, and then you will copy the contents of the file in a temporary
file, sort them there and then copy them back without the logically
deleted records.

Re: [Dev-C++] Multiple files in a project?

[Yeoh H. <ye...@ya...>]

Hi Stein,

I've used Dev-C++ and that is the way it currently works. To get around
this, you'll need to write a makefile.
There is a Generate Makefile menu option. However, the makefile generated
compiles all files. You can modify this generated makefile.
Another way is to refer to makefile from the MingW package.

Regards,
Yeoh

Re: [Dev-C++] student needs a little help

[Jason H. <jas...@bt...>]

Hi,

List structures are usualy taught early on in a programming course you =
may need to tell your teacher that you haven't yet been taught lists =
though? You may want to clarify whether you have to make your own list =
data type or if you can use a standardly available one. C++ defines a =
standard set of container objects that should be readily available in =
any up to date C++ distro, called the Standard Template Library (STL), =
and list is one of them. I would actualy use a map (also available in =
the STL) to implement the grocery list though. A map is a series =
<key><value> combinations, where you can look up a <value> using the =
<key> part. The STL also defines a range of access and search methods =
for you. However you may not be allowed to rely on ready made parts, =
although in the real world you would.

My best advise for you would be to arrange to talk to the teacher and =
ask about these things, because it would take a lot of effort to teach =
you about lists in a single e-mail. Books usualy have a whole chapter on =
them and how to use them. Try researching Algorithms and Abstract Data =
Types. There are probably some web-sites around that cover the subject =
too, anyone know any?

Jason.

[Dev-C++] Multiple files in a project?

[<ste...@ge...>]

Hey guys!

I'm working on a project, with I have 11 .cpp files so far. That sums up to
a lot of code, so the compililation takes a lot of time to complete. Is
there anything I can do to make the compilation go faster. Since most of the
files stay the way they are, it seems wierd to compile the same lines of
code each time *G*. Thanks!

[Dev-C++] 'New Source File' bug

[Devin C. <dcc...@ya...>]

  I came across a bug in Dev-C++ 4 some time ago, and now it's
gotten so annoying that I'm mentioning it in case no one else knows
about it.  When I create a new souce file in a large (15+ files)
project, and use Save As to rename it, often Dev-C++ refuses to
change the name in the project window (the one on the left.)  So I
don't know what it's saving, exactly.  Furthermore, I often get
phantom unnamed windows.  Clicking on the 'Unnamed1' in the
project window seemed to create new ones.  Last time, I tried to
chase them all these spurious windows down and X them out of
existence.  Then I saved and quit...causing a whole slew of red-X
windows errors and 'runtime error' complaints.
  I've had other problems with Dev-C++'s file handling.  Once it
didn't save something it should have.  (Fortunately it was only a short
header file, which I could easily recreate from the .cpp.)  The reason
I used 'Save As' in the first place is that some time ago I had similar
problems with selecting an unnamed file in the project window and
trying to change its name.  (I can't recall the exact details.)  I'm having
enough trouble with C++'s noodleheaded view of aggregate data
objects; this really isn't helping.  Any workarounds?  Has the problem
been tracked down?

  I think that the generalization is more than justifiable, and the
requestlikewise.
However, it doesn't seem likely that we'll manage to get through to this
person
  Way back when, in the Dark Ages of the Net (c. 1993) Usenet was not the
barren wasteland it is today.  Before the destructive Flame Wars, one could
shield oneself from repeated harassment by means of a 'kill file.'  Such a
thing
can be simulated today with most mail readers, even Microsoft products.

  I've set up my message rules in Outlook Express to direct such annoying
drivel to my 'deleted' folder, and mark it as read.  If it's really
bothering you,
make a message rule to delete messages with 'Auto Respond' in the subject
line from Mr. Horzum: it's not as good as getting him to stop, but it keeps
the
spam down to manageable levels.

RE: [Dev-C++] Binary Tree display

[Ioannis V. <no...@ya...>]

Except of what Jason said, try to make the recursive functions
non-recursive using loops. Recursion has both large time and space cost
with the last placing limits at the capacity of your tree since
dos/console only allows 64 kb of storage in the stack. Always (try to)
make the recursive functions non-recursive by using loop (e.g. for) and
placing the condition of the recursion ending as the condition of the
loop ending.

e.g.


int addall(int n)
{
  
  if(n<0)
    return 0;
  
  int count=0;
  
  count+=n; 

  if(--n)
   count+=addall(n);

  return count;
}


becones the time/space efficient:

int addall(int n)
{
 int count=0;
 
  for(int i=1; i<=n; i++)
     count+=i;

  return count;
}


 



 Doing this you will not be able to think again in recursive mode (which
is a good thing!) contrary to what smart-ass-but-know-nothing think. :)

Re: [Dev-C++] Binary Tree display

[Jason H. <jas...@bt...>]

Hi,

In main you only create one 'new' node for stem, and then you constantly
reuse it, and therefore write over it, every time you insert a node. You
need to create a new node for each new set of data and insert that.

Also in insert_node() you test for root being NULL, which it is to start
with, and then you do:

stem = root;

So the local stem becomes NULL and root doesn't change. I think you meant:

root = stem;

At the moment you aren't actualy inserting anything into the tree, root is
always NULL.

There may be other errors, but are the ones I found after skimming through
it quickly.

Jason.

[Dev-C++] Block indent?

[<mr...@c2...>]

Hi,

I haven't found a way to do block indents in the Dev-C++ IDE...

It is extremely annoying to have to manually indent (with tab) all 
the lines of a block that needs indenting.

Is there any way of doing block indent?

<DIV></DIV>Hello Aaron, 
<DIV></DIV>
<DIV></DIV>since you are developing console applications, my suggestion is: run them 
<DIV></DIV>from the console. In fact, when you use the console, there is no need to 
<DIV></DIV>add "cin.get" or "system("PAUSE")" or any other special instruction 
<DIV></DIV>preventing Windows from closing the window :-) 
<DIV></DIV>
<DIV></DIV>For instance, the following code would work as expected: 
<DIV></DIV>
<DIV></DIV>#include <IOSTREAM>
<DIV></DIV>int 
<DIV></DIV>main() 
<DIV></DIV>{ 
<DIV></DIV>std::cout &lt;&lt; "Please enter a number:"; 
<DIV></DIV>
<DIV></DIV>int n; 
<DIV></DIV>std::cin &gt;&gt; n; 
<DIV></DIV>
<DIV></DIV>std::cout &lt;&lt; "You entered: "&lt;&lt; n &lt;&lt; '\n'; 
<DIV></DIV>}

<DIV></DIV>&gt;http://www.cprogramming.com/close.html, it says that inserting the

<DIV></DIV>&gt;cin.get() before the return 0 line will keep the terminal window 
<DIV></DIV>&gt;open 
<DIV></DIV>&gt;until I press enter. This I find is true for the following program:

Hello Aaron,

since you are developing console applications, my suggestion is: run them 
from the console. In fact, when you use the console, there is no need to 
add "cin.get" or "system("PAUSE")" or any other special instruction 
preventing Windows from closing the window :-)

For instance, the following code would work as expected:

#include <iostream>
int
main()
{
   std::cout << "Please enter a number:";

   int n;
   std::cin >> n;

   std::cout << "You entered: "<< n << '\n';
}
