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
