Re: need help in object orientated programming
I need help on my mini project on object orientated programming. The
question goes like this:
A mini-mart has just installed a bar code reader to improve efficiency
at their checkouts.
Assume that the bar code is to access a file that store the product
descriptions, unit price
and quantity of each product sold in the shop. Assume that there are
only 10 products in
The format of the product stored in the file is shown below :
Barcode : a text string of 4 numeric character
Product description : a text string of 20 characters
Unit price : a floating point value
Quantity : an integer
Design the necessary classes and member functions to achieve the
following tasks :
a. Read the list of products available in the mini-mart from a text
b. Allow user to enter the bar code of a product via keyboard and the
purchase during check out.
c. Display the product description, unit price, quantity and the total
cost of all the
products bought by a customer.
d. Update the quantity of each product in stock after a purchase is
e. Write the bar code and product description to a text file if the
level of stock is less
f. Continue the program until user press a ?Q? to exit.
Please enlighten me on how can i start to write the program?
Every program should contain the 'main' function, so you can very easily
start to write your program by typing the following in your text editor:
If that's not a satisfactory answer, perhaps you should be more specific
on what it is that gives you the _real_ problem. If you have no idea
how to begin at all, perhaps you should talk to your instructor/teacher?
Do you understand the requirement "design the necessary classes"? Which
out of the 6 requirements are unclear? Why do I have to ask you those
Please remove capital 'A's when replying by e-mail
I do not respond to top-posted replies, please don't ask
