While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

contains a list of names and their corresponding coordinates. The program will then search for each name in the linked list and display the area of each coordinate.

Here's an example implementation in Python:

#

class Node:
    def __init__(self, name, x, y):
        self.name = name
        self.x = x
        self.y = y
        self.next = None

class LinkedList:
    def __init__(self):
        self.head = None

    def insert(self, name, x, y):
        new_node = Node(name, x, y)
        
        if not self.head:
            self.head = new_node
        else:
            current = self.head
            while current.next:
                current = current.next
            current.next = new_node

    def display_names(self):
        current = self.head
        while current:
            print(current.name)
            current = current.next

def read_coordinates(file_name):
    linked_list = LinkedList()
    
    with open(file_name, 'r') as file:
        for line in file:
            data = line.strip().split(',')
            name = data[0]
            x = float(data[1])
            y = float(data[2])
            
            linked_list.insert(name, x, y)
    
    return linked_list

def read_search_names(file_name):
    search_names = []
    
    with open(file_name, 'r') as file:
        for line in file:
            search_names.append(line.strip())
    
    return search_names

def find_area(linked_list, search_names):
    current_node = linked_list.head
    
    while current_node:
        if current_node.name in search_names:
            area = current_node.x * current_node.y
            print(f"Name: {current_node.name}, Area: {area}")
        
        current_node= current_node.next


# Read coordinates from a file and store them in a linked list
coordinates_list = read_coordinates('coordinates.txt')

# Display names from the linked list
print("Names:")
coordinates_list.display_names()

# Read search names from a file
search_names_list = read_search_names('search_names.txt')

# Find the area for each search name in the linked list
print("\nAreas:")
find_area(coordinates_list, search_names_list)
