Answer:

C.

Explanation:

An operating system is a route between the software system and hardware system in computers. This program helps to perform actions and execute applications. <u>Functionc performed by an operating system includes process management, handling files, controlling devices such as printers</u>.

The step which is not performed by an operating system while printing a document is that it does not create the document that has to be printed.

While printing, an operating system helps other system know if printer is busy with other operations. Other actions performed by an OS while printing document is that it sends the file, document, or data to be printed to the printer, it connects the computer system with printer.

Thus the correct option is C.

class UserName{

  ArrayList<String> possibleNames;

  UserName(String firstName, String lastName){

      if(this.isValidName(firstName) && this.isValidName(lastName)){

          possibleNames = new ArrayList<String>();

          for(int i=1;i<firstName.length()+1;i++){

              possibleNames.add(lastName+firstName.substring(0,i));

          }  

      }else{

          System.out.println("firstName and lastName must contain letters only.");

      }

  }

  public boolean isUsed(String name, String[] arr){

      for(int i=0;i<arr.length;i++){

          if(name.equals(arr[i]))

              return true;

      }

      return false;

  }

  public void setAvailableUserNames(String[] usedNames){

      String[] names = new String[this.possibleNames.size()];

      names = this.possibleNames.toArray(names);

      for(int i=0;i<usedNames.length;i++){

          if(isUsed(usedNames[i],names)){

              int index = this.possibleNames.indexOf(usedNames[i]);

              this.possibleNames.remove(index);

              names = new String[this.possibleNames.size()];

              names = this.possibleNames.toArray(names);

          }

      }

  }

  public boolean isValidName(String str){

      if(str.length()==0) return false;

      for(int i=0;i<str.length();i++){

          if(str.charAt(i)<'a'||str.charAt(i)>'z' && (str.charAt(i)<'A' || str.charAt(i)>'Z'))

              return false;

      }

      return true;

  }

  public static void main(String[] args) {

      UserName person1 = new UserName("john","smith");

      System.out.println(person1.possibleNames);

      String[] used = {"harta","hartm","harty"};

      UserName person2 = new UserName("mary","hart");

      System.out.println("possibleNames before removing: "+person2.possibleNames);

      person2.setAvailableUserNames(used);

      System.out.println("possibleNames after removing: "+person2.possibleNames);

Write a method named rotateright that accepts an array of integers as a parameter and rotates the values in the array to the rig
trasher [3.6K]
You should really state what language you are using. I have produced your method in C#, and should be easily translatable in to any other language.

static void RotateRight<T>(T[] arr)
{          
    T temp = arr[arr.Length - 1];
   
    for (int i = arr.Length - 1; i >= 0; i--)
    {               
        if (i == 0)                   
            arr[i] = temp;               
        else                   
            arr[i] = arr[i - 1];           
    }       
}

Out of a list of the values 2, 45, 18, 22, 8, and 37, what result would the MAX function return?
Vika [28.1K]
37 most likely.
No programming language is specified, and you didn't put what the function is, so assuming it's already implemented, MAX should display the highest number.
