Loops arrays, while

here is the code for the day. I may return to it to add comments later">

        //they want to enter
        //Then we will enter items and prices
        //into the two arrays
        //we will sum the prices and add tax
        //we will display a summary information
        //then we will ask if they want to enter 
        //another list. If they say yes we
        //will do it again, if no we will exit
