- Write a structure called box that has a length, width and depth (all doubles). - Write a free function called largest() that is given a Partial Array of box structures. It calculates the volume for each box as: length x width x depth. It returns the array index of the box with the largest volume. Example: [10 points] array length width depth calculated index volume 0 10 250 100 10 20 20000 2 50 30 20 30000 3 60 10 3000
