If you want to use a nested for loop to process a two-dimensional array row-by-row, which dimension’s index (row or column) would you increment in the inner loop, and which would you increment in the outer loop

How do you keep track of which entries in a partially filled array contain data?

In Python, use a for loop to take the elements 1-16 from a 1D array and place them into a 2D array.

Program: Using a multidimensional array, create a triangular-shaped array. You will ask the user how many lines they want to see and then create the array, fill it, and then print it. You will fill the array with one 1 in the first row, two 2’s in the second row, etc. This should work for any integer that the user enters. (Just because I am starting on 1 does not mean row 0 was skipped.) You must: use a loop to create the array shape. You must: use nested for loops to fill the array and to print the values back to the screen. Your program should print as shown below. Example Output: How many lines would you like in your triangle? >>>9 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9 If your code looks like the code below, it is not what I’m asking for. The code below is making a square multidimensional array, not a triangular one. The code below is just leaving certain spots empty so that it looks like a triangle. I will ask you...

The type size_t represents an unsigned integral type, which is recommended for any variable that represents an array's size or an array's indices. Select one: O True False

In what situations is it helpful to have data stored in an array with several dimensions?
