# Array output problem

Hey yall, here is another Im having problems with. Here is what I am supposed to do with this program:
1)Write a statement to declare a 20 x 30 two-dimensional array of doubles named MyArr
2)Write statements to fill out the array MyArr declared above with numbers from 0.0 to 599.0, row-by-row from top to bottom.
3)Write statements to find the sum of all elements in the array MyArr declared above.
I have it all covered but my loops only top out at 551.0 and not 599.0, what am I missing? Do I need a weapon R cold air intake system to get me over the hump? Here is the code.
Thanks yall.

The last I looked 19 * 29 = 551.

Yes, 19 * 29 = 551, but that sort of begs the question doesn't it? The correct formula is: (i * 30) + j, not i*j. However, it might just be easier to keep a counter and keep adding one to it.

I think he was pointing out the reason that your array "tops out at 551." Since you are calculating the values with i*j and the maximum values of i and j are 19 and 29, respectively, this means the maximum value in the array will be 19*29 or 551.

Yah, I'm sure it happens to all of us. I wanted to clarify just in case ;-)
Keep coding!

I was just trying to give a small hint, instead of solving your whole problem for you.
