Your image links may mean something to you, but I have no idea what they mean. All I can tell is that you want to sum some numbers, but in the array what numbers and how will you need to access the array?
The mind reading course I took has not worked yet, so I am at a loss as to what you need to do.
Be more specific about what you want and show some attempt to write some code.
As keskiverto once said:
Please note that this is not a homework site. We won't do your homework for you. The purpose of homework is that you learn by doing. However we are always willing to help solve problems you encountered, correct mistakes you made in your code and answer your questions.
We didn't see your attempts to solve this problem yourself and so we cannot correct mistakes you didn't made and answer questions you didn't ask. To get help you should do something yourself and get real problems with something. If your problem is "I don't understand a thing", then you should go back to basics and study again.
