macOS Help with Program Output?

[bravens52]

hey guys i just finished my cs program and i need help formatting it i need to get it to look like this:

http://faculty.cs.niu.edu/~byrnes/csci240/pgms/240pgm7.htm

(GO TO PART THAT SAYS VOID ARRAYS)!!!!




but i am getting this:


Annual Garage Sale
Family Item Id # Sale Price Quantity Sold Sale Amount
-----------------------------------------------------------------------------
Corinthos 12345 15.95 1 15.95
Morgan 67800 50.00 3 150.00
Webber 32145 4.50 2 9.00
Davis 98765 75.00 1 75.00
Spencer 44496 11.30 2 22.60
Drake 67356 3.50 4 14.00
Quartermaine 54862 52.50 1 52.50


This is the part in my program that does this information (Im using my setw()'s but i still dont know how to get it formatted to it can be neat and straight.

void printArrays(int family[], int item[], int quantity[], double price[], int numSales)
{



cout << " Annual Garage Sale \n";
cout << "Family Item Id # Sale Price Quantity Sold Sale Amount" << endl;
cout << "------------------------------------------------------------------------------------------------------" <<endl;



for (int i=0; i < numSales; i++)
{

cout << setprecision(2) << fixed << showpoint << familyName(family) << setw(20) << item << setw(23) << price << setw(23) << quantity << setw(20) << price * quantity << endl;

}

}

sorry about long post but if someone could be of some help that would be great.

Wasn't this due Wednesday? I see it's due by 11:59 PM this evening now.

How about something along the line of:

            // Item Id #
            std::cout << std::right << std::setw(9);
            std::cout << item[i];

            // Sale Price
            std::cout.precision(2);
            std::cout.setf(std::ios::fixed,std::ios::floatfield);
            std::cout << std::right << std::setw(15);
            std::cout << price[i];

I see that your assignments are available well before their due dates and that your next one, Assignment 8, is due "Friday, April 2 in the Blackboard Assignment Dropbox by 11:59 PM". If I were you (and I'm not) I would've started it by now.

It says here that Assignment 7 is due by "Friday, March 26 in the Blackboard Assignment Dropbox by 11:59 PM".

Anyway since Assignment 7 is past due I thought I'd throw this one out here for you to look over:
