Answer:

  1. #include <iostream>
  2. using namespace std;
  3. class myinteger {
  4.    
  5.    private:
  6.        int value;
  7.        
  8.    public:
  9.        myinteger(int x){
  10.            value = x;
  11.        }
  12.        
  13.       int getValue(){
  14.           return value;
  15.       }
  16.        
  17. };
  18. int main()
  19. {
  20.    myinteger obj(4);
  21.    cout<< obj.getValue();
  22.    return 0;
  23. }

Explanation:

Firstly, we use class keyword to create a class named myinteger (Line 5). Define a private scope data field named value in integer type (Line 7 - 8).

Next, we proceed to define a constructor (Line 11 - 13) and a getter method for value (Line 15 -17) in public scope. The constructor will accept one input x and set it to data field, x. The getter method will return the data field x whenever it is called.

We test our class by creating an object from the class (Line 23) by passing a number of 4 as argument. And when we use the object to call the getValue method, 4 will be printed as output.

Explanation:

Change the value of n in the main file for different array size. Output is in the same format as mentioned, time is shown in milliseconds.

Answer:

The answer is below

Explanation:

Elements of Server software that is built-in, in Windows workstations are:

1. Hard drives,

2. RAM (Random Access Memory)

3. Processors

4. Network adapters.

Windows Professional OS is not considered a server due to the following:

1. Windows Professional OS has a limit on the number of client connections it allowed.

2. Unlike Server, Professional OS uses less memory

2. In comparison to Server, Professional OS uses the CPU less efficiently

4. Professional OS is not built to process background tasks, unlike Server that is configured to perform background tasks.
