Structures Confusion

Hey guys, I am new to the forum. I'm taking classes for C++ at school.

I am having trouble getting the total and the average for my program. I don't know exactly where I should be putting it, but I have my full code below
(averageQuarterlySales and totalAnnualSales are the variables that need to work)

You can find your totals and averages easily enough, for example:

1
2
3
4
 
North.totalAnnualSales = North.firstQuarterSales +
                         North.secondQuarterSales +
                         North.thirdQuarterSales +
                         North.fourthQuarterSales;


and the average is:

North.averageQuarterlySales = North.totalAnnualSales / 4;

Thanks! Worked perfectly.

Line 29 is wrong! You have to specify North.firstQuarterSales and so on!

North.totalAnnualSales = North.firstQuarterSales +
                         North.secondQuarterSales +
                         North.thirdQuarterSales +
                         North.fourthQuarterSales;


I pared down your code to show one region:

North
First Quarterly Sales: 5
Second Quarterly Sales: 8
Third Quarterly Sales: 2
Fourth Quarterly Sales: 7
Total Annual Sales: 22
Average Quarterly Sales: 5.5

Yeah, I caught onto that after a minute or two. Thanks for your help though!
