The Problem description A database of laptops is kept in a text
file as shown below. The entries are brand name, number of models
(maximum number is limited to 5), model name, and price in that
order. A small segment of the file might look like the following.
Dell 4 Latitude 1000 Inspiron 750 XPS 2000 G15 3000 Lenovo 3
ThinkPad 1200 IdeaPad 1100 Yoga 1600 HP 2 ProBook 1300 Envy 1000
Apple 2 MacBookPro 3000 MacBookAir 2700 Asus 3 X515A 1200 ZenBook
1500 ExpertBook 1700 So, according to the data presented above, the
first brand is Dell; it has 4 models Latitude, Inspiron, XPS, and
G15; the prices of these models are 1000, 750, 2000, and 3000
respectively. The second brand is Lenovo; it has 3 models ThinkPad,
IdeaPad, and Yoga; the prices of these models are 1200, 1100, and
1600 respectively, and so on. Step 1: Create a text file that
contains the database of laptops as shown in the example above.
Declare an array of laptop structure shown below in main; the
maximum size of the array is limited to 100. laptop1.JPG Step 2:
Create a menu-driven C program Call a function named readDetails to
read the contents of the text file into the array of laptop
structure (function prototypes are given below). brandName: stores
the brand name of the laptop noOfmodels: stores the number of
models for a particular brand laptopName: stores the name of the
models price: stores price of the models Display the menu for the
user using a menu function. The contents of the menu function
should be: Enter 1 to display the laptop details Enter 2 to add
laptop details into a LinkedList Enter 3 to display LinkedList
Enter 4 to find average prices for a brand Enter -1 to exit the
program Option 1: displays all the contents of the array of the
laptop structure on a terminal as shown on the screenshot below.
Use displayArray function for this option. This displayArray
function must use the array of the structure to display the
details. Option 2: adds the contents of the array into a
LinkedList. Contents of the first array go to node 1 and contents
of the second array go to node 2 and so on. Use the fillLinkedlist
function for this option. Option 3: displays all the contents of
LinkedList on a terminal as shown on the screenshot below. Use
printList function for this option. This printList function must
use the LinkedList created in option 2 to display the details.
Option 4: ask the user to enter a brand name of a laptop and then
calculate and display the average price (precision-two decimal
places) of all the models of that brand, if there is no such brand
the program should report it back to the user. Use the
findAverageprice function for this option. This findAverageprice
function must use LinkedList created in option2 to calculate the
average. All printing happens in main for option 4. The program
should exit only when the user inputs -1. Your program must have 5
functions (function prototypes are given) in addition to the main
(3 marks): A readDetails//function 1 (3 marks) A menu //function 2
( 1 mark) A displayArray //function 3 (2 marks) A fillLinkedlist
//function 4 (3 marks) A printList //function 5 (3 marks) A
findAverageprice //function 6 (5 marks)
