Order Tracking sytem. Please help assp. I have no idea how to do!!!!!!!!!!!!!!!!!!

[luckystar89]

For this project we’ll consider a small business that needs an order tracking system. An Order is placed by a customer to purchase a product. The order system must be a menu-driven system that allows the user to add orders, view an order, find an order(s) by date, or list all orders made in that run of the program. We will not “persist” (save it to disk) the data from one program run to another, meaning we’ll have to enter all data every time.
Data analysis: An order is comprised of an order number, a date of order, a customer placing the order, and one product. A customer is comprised of a first name, a last name, and a company phone number. A product is comprised of a sku (product number) a description, and a unit price.
In this assignment, you’ll need to create unrelated classes for each object mentioned (notice they are nouns; when analyzing data needs before writing a program, the classes you’ll need to create are usually people, places, things, and transactions mentioned by the client), Product, Customer, and Order. You may want to create another class to encapsulate the entire operation and act as “program central”.
Each class should have at least two constructors, appropriate set and get methods; you’ll need to overload the stream insertion and extraction operators for each class so that the program user can be prompted for the required inputs that are added directly into the objects. Your driver program used to test your application, should present a simple menu as stated above or call your “central” class; it should also serve as the data repository (where your data is stored) and allow the functionality stated in paragraph one. The Date class is provided (you’ll need to overload the comparison operators) see the Date.h and Date_M.cpp files for details.

Please help
Or
Can you give me a sample of this ?????????????????

No.
We won't do your homework for you.
Show what you've done so far, and you'll get help. Coding the lay-out of the classes shouldn't be too hard.

ps. Adding 20 questionmarks and exclamationmarks won't help either.

[n1337]

What have you done so far...? What specifically do you need help with?

Do you have any thoughts on how to solve the problem? If so describe them...If you have any code, post it so we can see where you are at with the problem.

I would like to ask what/where did I did wrong? What do I have to do next to fix it?

Also How can I find the order by date?

Please help. Thanks

[Nick Evan]

Does it compile?
if yes: what output were you expecting, and what is your output?

Use code-tags when posting code here, it makes it easier to read (smilies will disappeare) and your chance that you'll get some help will increase

[luckystar89]

Ok .I got succeed when I fix all the tiny mistakes but The output was not what I expected. I want it to appear all the data ( date, order......) that I input when I click "2" but It just did nothing . PLease help. Just tried to help me which code is totally worng and don't care about any tiny mistakes . Thanks

[tesuji]

Use code tags, repost your code, and maybe you touch it up first, making that code more readable.

case '1':
for (int i=1 ; i < numorder;i++)
{
InputCustomer(fn,ln,ph,ordernumber,mm,dd,yy,num,desc,cost);
return userchoice;
}
sytem("cls");
print();
break;

btw, return placed correctly? what the hell is system(;) )?

[n1337]

Also How can I find the order by date?

I'll be honest, I haven't looked at your code at all, partly because its so long and the formatting makes it difficult to read...

But anyway, my first thought when reading the question was to make a struct containing all the required information, i.e. struct order which contains the date of the order, the sku, the description, the price, and a pointer to the next order (like a list). This way, you can add orders in constant time....Then you can just create accessors to return the information that you query...

Another way you could do it is in each class, create side-by-side arrays (or vectors to have the added capability of resizing the array to add a new order). That is, you have a date array, a sku array, etc, all of the same size, and you store corresponding orders into the corresponding elements of each array...That way, you just search for the date in the array, and use the index number of the date to return the order (stored in the same index of the other array)...

In any case, of these two ideas I like the list-structure one better, because it can add new nodes in constant time, and will take O(n) time -- roughly proportional to the length of the list (number of orders) -- to find any specific order, which will actually be the same case as with the arrays (because although you have constant time access, you don't know where to access!)

Of course, someone might be able to come up with a better idea...

[luckystar89]

Dear. I would like to ask how to do I make a pointer to the next order (save or make a list in order view the all data and find the data).

Also. I would like to ask what wrong with this code. It doesn't work.

pday =1;
pyear;
int daysPerMonth[  ] = { 0, 31, 28, 31, 30, 31, 30,
                              31, 31, 30, 31, 30, 31 };
int testMonth1 [ ] = {1,3,5,7,8,10,12};
int testMonth2 [ ] = {2,4,6,9,11};

if( mn.month >0 && mn.month < 13 &&
		        dd.day > 0 && dd.day <= 31 && yy.year > 2006 && yy.year < 3000)
	 {
		 if (mn.month ==2 && dd.day == 29 && 
                         ( yy.year % 400 == 0 || (yy.year % 4 == 0 && yy.year % 100 != 0 ) ) )
		 {
			if (mn.month == testMonth1[mn.month] && mn.month <32)
			{
				if (mn.month = testMonth2[mn.month] && mn.month <31)
				{
					pmonth = mn.month;
					pday = dd.day;
					pyear = yy.year;
				}
			}
		 }
	else
		{
			cout<<" Invalid date. Please try again";
			cout<<"\nEnter the date by mm, dd yy: ";
			cin >> mn.month>>dd.day>>yy.year;
		}

[Nick Evan]

Ofcourse it doesn't, just look at the first 3 lines.
- Where is the rest of the code?
- What is it suppose to do?
- Does it compile?
- What output are you expecting?
- What output do you get?

And please please with sugar on top USE CODE TAGS...
(this time click the link and read it)

[VernonDozier]

code = cplusplus

No spaces in code = cplusplus, like this:

[code=cplusplus] // paste code here

[/code]

pday =1;
pyear;

Are the data types defined earlier? C++ requires you to declare the data type.

Hey guys. I have done the project so far but I would like to like to ask how could I save my data every time I input in order to view . I tried to use the dynamic array and the istream but It seems not to work with me. PLeasee help assssssssssssssspppppppppppppppppppppppppppppppppppppp

No one can tell you what the problem is because you haven't posted what you have tried.

I tried to use the dynamic array and the istream but It seems not to work with me.

There is no way to know what you did here so how can we help?
