Explanation:
It's not A because all modern computers use some form of an Operating System.
It's not B because some Operating Systems can cost hundreds of dollars.
While C has some truth to it, it's reversed. Operating Systems are there to manage and allocate system resources, and D is the better choice.

So there are separate soft skill training provided for various roles and years of experience. So, I suggest to have soft skill training and do additionally MBA degree.
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
Complete Question:
Write statements that output variable numComputers as follows. End with a newline. There are 10 computers.
#include <iostream>
using namespace std;
int main()
{
int numComputers;
cin >> numComputers; // Program will be tested with values: 10.
...
return 0;
}
Answer:
cout << "There are ";
cout << numComputers;
cout << " computers." << "\n";
Explanation:
Using three cout statements the string "There are 10 computers." is printed out, notice that the variable numComputers is entered by the user when the program is run. Another way of concatenating an integer variable and string for printout is by the use of the + (plus) operator.
