this is my question..


To model this application, write a base class called ShippingContainer that has a container ID number as an integer. Include member functions to set and access the ID number. Add a virtual function called getManifest that returns an empty string. The purpose of this function is to return the contents of the shipping container.

Create a derived class called ManualShippingContainer that represents the manual method of inventorying the container. In this method, a human simply attaches a textual description of all contents of the container. For example, the description might be “4 crates of apples, 10 crates of pears.” Add a new class variable of type string to store the manifest. Add a function called setManifest that sets this string. Override the getManifest function so that it returns this string.

Create a second derived class called RFIDShippingContainer that represents the RFID method of inventorying the container. To simulate what the RFID chips would compute, create an add function to simulate adding an item to the container. The class should store a list of all added items (as a string) and their quantity using the data structures of your choice. For example, if the add function are invoked three times as follows:

rfidContainer.add(“crate of pears”); //add one crate of pears
rfidContainer.add(“crate of apples”); //add one crate of apples
rfidContainer.add(“crate of pears”); //add one crate of pears

At this point, the data structure should be storing a list of two items: crate of apples and crate of pears. The quantity of apples is one and the quantity of pears is two. Override the getManifest function so that it returns a string of all items that is built by traversing the list of items. In the above example, the return string would be “2 crate of pears, 1 crate of apples.”

Include other necessary functions, constructors, and destructor to all the classes above.

Finally, write a main program that creates an array of pointers to 6 ShippingContainer objects. The array should be used to store both the ManualShippingContainer objects and RFIDShippingContainer objects. Construct the main program to allow the user to decide the number of each type of objects to be stored in the array. Instantiate all the objects accordingly and demonstrate how each objects behaves differently when the same instructions are given to them. For the ManualShippingContainer objects, you will have to invoke setManifest function to set the contents. For the RFIDShippingContainer objects, you will have to invoke add to set the contents (although, if this were real, the contents of the container would “add” themselves via the RFID chips instead of requiring a human to type them in).

now the problem is i know inside RFIDContainer should have the string parameter , but i don't know how to do some function that will return automatically for my quantity if it detected my

content == content

then quantity will be keep adding .

someone help please...

Well, obviously you need some sort of container in RFIDShippingContainer. A map with a string as the key and the count as the associated data may work.

One string and one count simply aren't going to do it.
BasicNewbie (145)
if i use data structure to do? as the question required, then it is easier?
guestgulkan (2942)
As already suggested to you both by myself (in your other thread) and and now by cire - you could do with some sort of data container ( vector or list or linked list, etc.. ) in the RFID container class - if you don't know of any of these data structures I have mentioned, then you are on a losing streak!

Are you familiar with arrays??

If this is part of a C++ course and you are expected to hand in this work to be graded - then why have you been given an assignment which needs
some C++ information that you have not been taught - this surprises me.

help us to help you (as they say)...

Edited for empathy..
