Sorting information from array with Operator Overlaoding

MarkLeonis (4)
I have a program in which I take information from a csv, store it in an array, and display it.

I want to display the information a second time but this time I wanted the output sorted via operator overloading and sorted to display it alphabetically from a to z based on ProductName. ( Yes this is an asssignment, but we all learn somehow).

It does not work for some reason.

Any input what I am missing? Help appreciated.

( And I have to use arrays and operator overloading for it:

Sort the Products alphabetically based on the Product Name. Use relational operator overloading within the product class for this

)

Your code doesn't have a call to a sort function of any kind. If you are wondering why it doesn't sort, well there you go. Does the assignment specify the sort algorithm to use?

webJose,

I inserted a sort function now that I used previously and still cannot find what is wrong. Any ideas?

I would appreciate any help with. It is supposed to be sorted alphabetically (ProductName).
