For the array myArray[a][b], what represents the column subscript?

In an array denoted as myArray[a][b], the first index, which is 'a', typically represents the row subscript, while the second index, 'b', represents the column subscript.

This convention arises from how multi-dimensional arrays are structured in programming. The first dimension typically corresponds to rows and the second dimension to columns. Therefore, when referring specifically to the column subscript in this context, 'b' is the correct choice, as it directly indicates the position within the column for a specific row.

Understanding this structure is crucial for effectively manipulating arrays, especially when performing operations such as traversing through rows and columns or accessing specific elements within the array.
