Write a program that defines an interface having the following methods: addition, subtraction, multiplication, and division. Cre
Tatiana [17]

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

Illustrate why Sally's slide meets or does not meet professional expectations?
givi [52]

The correct answer to this open question is the following.

Unfortunately, you did not provide any context or background about the situation of Sally and the problem with her slides. We do not know it, just you.

However, trying to be of help, we can comment on the following general terms.

When someone does not meet professional expectations, this means that this individual did not prepare her presentation, lacked technical skills, did not included proper sources, or missed the proper visual aids to make the presentation more attractive and dynamic.

What Sally can improve about her slides is the following.

She can design a better structure for the presentation to have more congruence.

Sally has to clearly establish the goal or goals for her presentation.

She has to add many visuals instead of plain text. This way she can better capture the interest of her audience.

If she can use more vivid colors instead of pale or dark ones, that would be best.

No paragraphs unless necessary. She better uses bullet points.

Take care of the tone of her voice. During her practice, she can record her vice to check how it sounds.
