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
Answer:
<u>He wants to easily and quickly find specific bits of research that cover certain topics.</u>
<u>Explanation:</u>
Remember, a research work typically has these 6 (six) components:
- The Abstract.
- Introduction
- Methodology
- Results
- Discussion
- References.
Thus, Aika's decision to label several folders for different parts of his research would make it easier and quicker for him to find specific bits of research that cover certain topics, instead of spending time looking for topics.
It’s 12 because 3 times 4 is twelve, hope i helped!
I believe the answer could be the first choice. I'm not quite sure, though
Cryptography is not a reason to use when posting photos on a public social media website.
Cryptography is the use of certain techniques that help protect important and personal information from being accessed by other parties. This technological practice or method allows a person to send sensitive or personal information over the internet without risking any "leak" of information.
- Cryptography literally means "hidden writing", which is what the method is all about.
- It presents a safe and secure way of sending or passing information, even personal or sensitive ones.
- This technological method enables businesses and other companies as well as individuals to procure and send information without fearing for any loss of their information.
- Cryptography is mainly used in the military, secret operations, businesses, or even in maintaining one's passwords while using social media platforms or submitting a password on a website.
- One reason to not use it is when posting photos on social media websites as the website is to be used by the web world and may/can be accessed by everyone around the world.
Cryptography not only allows a person to maintain certain privacy and security but also help the smooth functioning of businesses and other national security works. Thus, cryptography is the "security" of individuals in the 'internet world'.
