i wrote this code to display a shop
am getting error
error no matching function for call 'RetailItem::RetailItem()
so can any one example or help with the error

You probably declared a constructor for RetailItem with some arguments. If you did that, the default constructor (RetailItem::RetailItem()) is not automatically created. Your first line on main creates a RetailItem calling its constructor with no arguments.
