Explain why you might want to use a two-dimensional array.
What will be an ideal response?
Sometimes locating a value in an array depends on more than one variable. If you must represent values in a table or grid that contains rows and columns instead of a single list, then you might want to use a two-dimensional array. A two-dimensional array contains two dimensions: height and width. That is, the location of any element depends on two factors. For example, if an apartment's rent depends on two variables-both the floor of the building and the number of bedrooms-then you want to create a two-dimensional array.
