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
Explanation:
Start
Input dollars
Set Euros = 0.91 * dollars
Set Yens = 109.82 * dollars
Output Euros
Output Yens
Stop
Note: The rates are as of 07-Feb-2020
Answer:
for(let i = 0: i <=5; i++) {
console.log(I)
}
Explanation:
An iterative statement repeats a body of code until the condition is not true. Here we declare an integer (i) and make it 0. Then the loop checks if the second part is true (i is less than or equal to 5), and if it is true, it executes the code inside the loop body, which logs i, and finally runs the last past, which increments i by one. When the second part becomes false, the loop exits.
The answer to this question is: CE
Calculator will memorize the input that you made from previous calculation until you press the = button.
CE stands for clear data, which means that by pressing this, you will eliminate the calculation from previous effort and start the new calculation on a blank state
The SDLC would be the usually used methodology by web project teams. Also known as the systems development life cycle, this kind of application development process is primarily used in information, computer, and software engineering which involves planning and testing applications.
