Hello, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.
Answer:
1. # -*- coding: utf-8 -*-
2. #Python
3. class Calculator:
4. def add(self):
5. print(a + b)
6. def sub(self):
7. print(a - b)
8. def mul(self):
9. print(a * b)
10. def div(self):
11. print(a / b)
12.
13. obj = Calculator()
14. choice = 1
15. while choice != 0:
16. a = int(input("\nEnter first number: "))
17. b = int(input("Enter first number: "))
18.
19. print("\n0. EXIT")
20. print("1. DIVISION")
21. print("2. ADDITION")
22. print("3. SUBTRACTION")
23. print("4. MULTIPLICATION")
24.
25. choice = int(input("\nEnter your choice: "))
26. if choice == 1:
27. obj.div()
28. elif choice == 2:
29. obj.add()
30. elif choice == 3:
31. obj.sub()
32. elif choice == 4:
33. obj.mul()
34. else:
35. break
Explanation:
- From lines 1 to 12 we define the object with four methods, addition, subtraction, multiplication, and division. Each method contains the operation between two variables inside a print function
- On line 13 we instantiate our class
- On line 14 we declare the variable choice that is going to store the operation that the user wants to perform
- On line 15 we declare a while loop, this is going to keep running the program until the user wants to exit
- From line 16 to 18 we ask the user to enter two numbers
- From line 19 to 24 we print the possible operation, assigning a number for each operation, this indicates to the user what number to press for what operation
- On line 25 we ask the user for the operation
- From lines 26 to 35 we check the user input an accordingly we call the corresponding method to performs the operation
TCP tells or state how applications can make channels of communication across a network.
<h3>What is the role of TCP?</h3>
TCP is known to often help in the management of how a message is put together into smaller packets before they are sent or transmitted over the internet and then put together again in the right way at the arriving or destination address.
Therefore, TCP tells or state how applications can make channels of communication across a network.

Answer:
1. get the absolute path to the file
2. load the file as a table (dataframe in python)
3. to insert a row;
- create a dataframe of the same field type
- concatenate the new dataframe horizontally with the same dataframe
4. to delete a row, select and drop the row where the 'Number' field matches a value.
5. to update the values in row, use the number field as a key to replace the existing values.
6. print of save to a variable the rows where the number field matches a given value.
Explanation:
Follow the report template to create a report for the algorithm.
The algorithm gets the absolute path to the file and loads the file as a tabular file from there the data can be queried without accessing the main file. The insert algorithm creates a new dataframe and appends it to the main dataframe.
The delete, update and retrieve all use the same subalgorithm, getting the rows with the number field as the key value.
