Okay, the problem i'm having is, I have one last thing to do on this project and have spent a few hours trying to figure out, how do i do it?

I need to figure out how many seats are available in each row.

I will use a for loop to display the seats in each row, but I am unsure on how to actually figure out how many seats are available in each row, so that it changes as it counts, and doesn't repeat the same thing.

The seats available in each row will be displayed within "Case: 5".

To know how many seats are available in each row, you need to use the same loop structure you have in the DisplaySeats( ) function to count up the number of seats marked available as you loop through each row.

Be sure to reset your counter to 0 as you start each new row's count.

How do i reset the counter to 0 for each new row :o ?

Sorry, I'm obviously new :s

The general structure is something like:

``````for( i = 0; i < maxrows; i++ )
{
sum = 0;
for( j = 0; j < rowsize; j++ )
{
//add to sum the value from each row element
//dislay the row's sum
}
}
``````
``````for (int i = 0; i < 15; i++)
{
int sum = 0;
for (int j = 0; j < 30; j++)
{
sum =  + sum;

cout << "The sum is " << sum << endl;
}
}
``````

---------------------------------------------------------------

okay this is what i've got but i'm getting alot of weird numbers because i'm not sure
of what is actually being added to sum.

i've been doing this program all day... my brain must be getting tired. :(

btw, that's not my final output statement, I was only testing.

To count how many seats have been sold, what do you need to be looking at? Each row of the seats array contains some number of '#' and '*' characters. You want to be counting how many are still '#'.
