I am studying for my Programming 1 final and I am having a little trouble with this problem on my study guide. Any assistance would be greatly appreciated. The problem is as follows.

Show how to declare a 2 dimensional array of integer values. This array should have 5 rows and 300 columns. Next, show the code necessary to fill this array with random values ranging from 0 up to 99 (including both 0 and 99). Finally, show the code necessary to sum up the values in each column and display the sum of each on the screen.
