Higher Dimensional Arrays You may be thinking, if two dimensional arrays are just arrays of arrays, can I make higher dimensional arrays as well? Sure. You can make 3,4, 5 and even higher dimensional arrays if you wish. All you have to do is append more square brackets on the end. For example, the following declares a 4 dimensional array of doubles: double arr4D new double 100 J [100] [100] [100 An array that size would have a hundred million elements! Are such structures useful? Yes, and they abound in scientific and multimedia applications. For example, an MRI scan produces a 3 dimensional volume of data that shows a person's body on the inside. A movie is just a time series of images (3 dimensions). A simulation to analyze the aerodynamics of an aircraft wing might compute a the airflow at every point in space around the wing over time. This is a 4 dimensional structure (3 spatial dimensions and 1 time dimension). To iterate over this aITay would require a nested loop that is 4 deep! Q4) What code would you use to create a 3 dimensional array of int called b, with 10 elements in each dimension? Write the answer in lab8answers.tkt. Part 6) Finish the code below, writing the 3-deep nested loop needed to set all of the values in arr to 1.5 (hint: you will need 3 different loop variables to do this)
