I need to understand a code for cumulative sum in 2D array in c++

Question

a task is required from me

Answer 1

Use a for loop nested inside of a for loop. The outer for loop will be how many arrays are contained within the total array, and the second will be the number of elements in each array.
If you are asked to do something, you shouldn't ask others to do it for you. You should research and try to figure it out yourself, because you are obviously expected to know how to do it.

Answer 2

Good that you tried, I can't really make a code out of your example, but I can make my own.
(array defined as [3][4])
for(int i = 0; i <= 2; i++){
for(i = 0; i <= 3; i++){
System.out.println(array[i]);
}
}
