Chapter 7: Problem 17

A video rental store keeps videos on 50 racks with 10 shelves catch. Each shelf holds 25 videos. Declare a three-dimensional array large enough to represent the store's storage system.

Short Answer

Expert verified
Answer: To create such a three-dimensional array, declare it with the dimensions representing racks, shelves, and videos, like this: ```c int storage[50][10][25]; ``` This array, named 'storage', has 50 racks, 10 shelves per rack, and 25 videos per shelf.

Step by step solution

01

Understand the dimensions

To represent the storage system using a three-dimensional array, we must first understand the dimensions of the problem. The storage is composed of 50 racks, with 10 shelves each, and each shelf can hold 25 videos. Thus, our array will have the following dimensions: 50 (racks) x 10 (shelves) x 25 (videos).
02

Declare the three-dimensional array

Now that we know the dimensions, we can declare a three-dimensional array to represent the storage system. In this case, we'll be using an integer as the data type to represent different video titles (assuming we'll use a unique integer value for each video). Here's the declaration for such an array: ```c int storage[50][10][25]; ``` This creates an array called 'storage' with the dimensions specified earlier: 50 racks, 10 shelves, and 25 videos. Now the storage system can be represented using this three-dimensional array.
