Question

Design an application that stores different types of products available at a local IT store and the corresponding product price. The product details must be stored in parallel arrays. Use the following data to populate the three (3) parrallel arrays in a loadArrau ()method.

Create a SearchArray () method and write the code to enable the user to search for a specific type of product and if the product ID is listed in the array, show the product details. If the product ID that the user searched for does not exist in the array, show a message to indicate that this product is not available.

Prompt the user to enter numbers 1,2 or any other key to exit the application.

The product ID , product name and the product price must be displayed in a message box if a valid product ID is entered by the user.

Implement user friendliness into the application by prompting the user if they would like to search for more products.
