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
The answer should be B tell me if I'm wrong.
Answer:
<a href="enter_site_url_here">Click here to visit site!</a>
Explanation:
href is the link that the element is going to point towards. Meaning it's going to direct the end-user to that site. "Click here to visit site!" is the text that the element is going to say, and that text will have an underline. So it's best to keep it short as you don't want <u>something like this happening on your site</u>.
I'd stick with the classic "here" as the text and have the text before-hand say "Click" and after-hand say " to visit site X" with X being the site name. Or, something along those lines.
Answer:
Program memory is paged, this statement is defined as in a computer system paged memory is the process of allocation of memory and storing a portion of a process of execution. Page is a unit of logical memory in a program. It follows the process of paging, as it is a method of writing an information and reading the output from the storage drive. The main advantage of this process is that it become easy to swap because everything is the same size.
