Array of Objects, what is it? ASAP

[mwhit74]

no code to see, but my professor wants an array of objects rather than 3 parallel arrays. i dont need another way to do the same problem or something fancy, it is an introductory course. all i need to know is what an array of objects is and how it works. I have looked in my book and on other online sources nothing is giving me a clear answer.

Possibly a simple program with them in use, i think this would be most helpful

As for as i know array of onjects would be in arr[3].
Here is consider int as the object.
I am not getting ur question fully.

ok here i will quote the assignment, "Project 3" in the quote is a previous project but it really doesn't matter.

"1. Rewrite Project 3 using an array of object, rather than the three parallel arrays of Project 3.

Create a class named inventory , there are 3 data fields: itemId, storeNr, and quantity. Design the necessayr header file and implementation file."

further down the assignment she defines some of the variables we are supposed to use and 3 functions we are supposed you use in the program.

this is the part i am confused about. can you tell whay you would think a professor would want.

Sorry,,,
I am not able to get a clear difference between array of object and three parallel arrays of Project.

You have probably done the following in your previous project:

/* <max_value> is some positive value */
int itemId[<max_value>];
int storeNr[<max_value>];
int quantity[<max_value>];
 

Now the assignment wants you to design a small class named 'inventory' such
that you can do this:

/* <max_value> is some positive value */
inventory items[<max_value>];
 

kind regards,
