how to put classes into a 2d array

[HarisHohkl]

Hi, my programme using visual C++ need 3 classes, 1 for 'item tv', 1 for 'shelf' and the other 'warehouse'. The 'item tv' class will update and display the item number, description, cost and qty of 3 tv. The shelf will capture the item no. and qty of any of the 3 tv of the "item class " and ask where to put the item in the 2D array. It will then display the 2D array, add up the total qty and the cost. The warehouse class will have a address using dymanic menory to create a new address and display the address. How shall i being....Thank

Well, if you look at the BMP object in EasyBMP.cpp in my EasyBMP C++ bitmap library, you'll find that the pixels are a 2-D array of ebmpBYTE structs:

BMP
{
 private:
  ebmpBYTE** Pixels;
  // ... 
};
 

I'd recommend studying that example. While the ebmpBYTE's are structs and not objects, the idea is exactly the same. Incidentally, it's also the same as doing a 2-D array of double's or any other type.

One thing I suppose you'll need to be careful of, however, is that your default constructor and destructor functions for your item class are properly-debugged.

Best of luck! :) -- Paul

implement and test each class in turn, i.e. implement and test tv, when that is working shelf then warehouse, etc. in this way you build a working system knowning that each component it tested and working before you move to the next.

Best advice I've seen all day! (And way better than mine!) :) -- Paul

Hi, i have done up my programme, need ur advice on how can i capture the tv classes data and put it to the shelf. is there any way i can sent the code to u?

[HarisHohkl]

I've done up the programme, need help to fine tune it, as the shelf classes cannot receive data from the item classes. my shelf classes need to capture the item no and cost of the 3 TV items. Thanks for the time in viewing

[horace1]

thanks for the help, but how come it can't display the total amount for the tv??[

I only modified update_shelfs() and display_shelfs() and the code which called them, i.e. options 1, 2, 4 and 5 now appear to do something. If they do what you require you now need to look at display_total_all_items_stored() and display_total_value()

[HarisHohkl]

for the display total item, it can add up all but not for the total value. how can i ask the programme to go to the item classess to capture the cost of the item for each indivual tv and multiply it to get the total???? thanks[
