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?

Expert Solution

Step 1

Here, we need to print or assign the values from left to right in a same row.

So, for the same row we print values in each column.

thus, for printing tracking the row number, we use one for loop and for tracking the column, we use another for loop.

If you want to assign the values in row major order, then we have row in outer loop and if you want to assign the values in column major order, then we have column in outer loop.
