Left and right manipulators

grider67 (28)
I'm trying to set up manipulators for Product description, Unit price, Quantity and Total but Unit price is not right under the shifted Product description. Also I get

Error C4700 uninitialized local variable 'price' and 'quantity'

How do you set it up?

You don't need the cout << right; and cout << setfill(' '); since those are the defaults. And even if you did need them, you would only need to do them once.

Also, you are trying to print price and quantity (with cout) before you even read them in (with cin). You need to read them in first.

If you want things to be farther to the right you either need to print some spaces (or possibly tabs) or make the setw value a lot bigger.

Ok now I have the Product description in the right spot.
How do I get Unit price, Quantity and Total following right under/

I didn't correct the other issues tpb mentioned; I just fixed the alignment. (If you want 'them' more to the right...just increase the setw() value.)

Thanks for the help again...
I fixed now. It was depending on how many letters were being used within each setw. The longer the word; the longer the setting numbers for it. Here's how I fixed it with your help...

Cool!
grider67 (28)
Next question is...
Why am I not getting a decimal layout like on Line 50 for Line 33?
and
How can I cinch up the spaces between the output?
i.e.
Like the example between Lines 16 to 22.
