You designed a program to create a username using the first three letters from the first name and the first four letters of the last name. Usernames cannot have spaces. You are testing your program with a user whose name is Jo Wen. What step in the program plan do you need to revisit

Answers

Answer 1

Answer:

See Explanation

Explanation:

The question would be best answered if there are options to select from; since none is provided, I will provide a general explanation.

From the question, we understand that, you are to test for Jo Wen.

Testing your program with this name will crash the program, because Jo has 2 letters (3 letters are required), and Wen has 3 letters (4 letters are required)

So, the step that needs to be revisited is when the username is generated.

Since the person's name cannot be changed and such person will not be prevented from registering on the platform, you need to create a dynamic process that handles names whose lengths are not up to the required length.

Sixteen stations, numbered 1 through 16, are contending for the use of a shared channel by using the adaptive tree walk protocol. If all the stations whose addresses are prime numbers suddenly become ready at once, how many bit slots are needed to resolve the contention

Answers

Answer:

11 bit slot will be needed

Explanation:

The number of prime numbers between 1 through 16

= 2, 3 , 5, 7, 11 and 13

hence we can say 6 stations are to use the shared channel

Given that all the stations are ready simultaneously

The number of bit slots that will be needed to handle the contention will be 11 bits :

slot 1 : 2, 3, 5 , 7, 11 , 13

slot 2 : 2,3, 5, 7

slot 3 : 2, 3

slot 4 : 2 .   slot 5 : 3 .  slot 6 : 5,7.   slot 7 : 5 .   slot 8 : 7.  slot 9: 11,13.  

slot 10 : 11.   slot 11 : 13

Use the man or info page to find out how to use this utility, and use it to add three users. When finished, view the /etc/passwd, /etc/shadow, and /etc/group files to verify that the users were added successfully.

Answers

Explanation:

Given - When adding several user accounts, you might want to use the new users utility, which can process a text file full of entries to add user accounts.

To find - Use the man or info page to find out how to use this utility, and use it to add three users.

Proof -

New Users Utility:

It is an utility which reads the file full of usernames and clear text passwords.

It then uses this information to update a group of the existing users to create new users.The format of the file consists of specified things like:

pw - passwd

pw - age

pw - gid

pw - dir

Use of the Utility:

The command is new users filename

The file should look like -

(Username : Password : UID : GID : User Information : Home Directory : Default Shell)

where ,

UID = User Identifier

GID = Group Identifier

Testing the Users:

Creating users from the file given above test User 1, directory Of File

Executing the create user new users directory Of File

Repeat this step to undergo all the users that are been noted down in the file to make them a user in the noted group policy.

Hence,

These are the steps of using the new Users utility.

Write a program that will create an array of random numbers and output the values. Then output the values in the array backwards. SPECIFICATIONS: File name: ArrayBackwards.java Your program must make use of at least one method other than main()to receive full credit (methods can have a return type of void). Suggestion: create and populate the array in the main() method. Make a method for Step 3 below and send in the array as a parameter. Make another method for Step 4 and send in the array as a parameter.

Answers

Answer:

The program is as follows:

import java.util.*;

public class Main{

public static void backward(int [] Rndarray, int lnt){

    System.out.print("Reversed: ");

    for(int itm = lnt-1;itm>=0;itm--){

        System.out.print(Rndarray[itm]+" ");     } }

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 int lnt = input.nextInt();

 Random rd = new Random();

 int [] Rndarray = new int[lnt];

 for (int itm = 0; itm < lnt; itm++) {

        Rndarray[itm] = rd.nextInt();

        System.out.print(Rndarray[itm]+" ");

     }

     System.out.println();

 backward(Rndarray,lnt); }}

Explanation:

This defines the backward() method

public static void backward(int [] Rndarray, int lnt){

This prints string "Reversed"

    System.out.print("Reversed: ");

This iterates through the array

    for(int itm = lnt-1;itm>=0;itm--){

Each element is then printed, backwards

        System.out.print(Rndarray[itm]+" ");     } }

The main begins here

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

This gets the array length

int  n = input.nextInt();

This creates a Random object

Random rd = new Random();

This declares the array

 int [] Rndarray = new int[lnt];

This iterates through the array for input

 for (int itm = 0; itm < lnt; itm++) {

This generates a random number for each array element

        Rndarray[itm] = rd.nextInt();

This prints the generates number

        System.out.print(Rndarray[itm]+" ");

     }

This prints a new line

     System.out.println();

This passes the array and the length to backward() method

 backward(Rndarray,lnt); }}

With RAID 0 or RAID 1, you'd require at least two drives, so you would require to buy one additional drive in most cases. With RAID 5 you'll require at least three drives, so two additional drives, and with RAID 6 or 10 you'd require at least four total drives.

1-How many moles of NazCOs are in 10.0 ml of a 2.0 M solution?​

Answers

Answer:

A solution is a mixture in which the particles are so small that the components are indistinguishable from each other. The amount of the solute and the solvent in a solution can be expressed in terms of different concentration expressions such as molarity, morality, etc.

Explanation:

To calculate the number of moles of sodium carbonate, the volume in liters will be multiplied by the molar concentration of the solution.

moles Na2CO3 = 2.0 M  x 0.0100 L = 0.020 moles Na2CO3

Hope it helps :)

Answer:

There are 20. mol of Na2CO3 in 10.0L of 2.0M solution.

Explanation:

Molarity is represented by this equation:

(look at attachment)

In our case, we already have the molarity and volume of solution, both of which have good units.

Let's rearrange the equation to solve for the number of moles. We can do this by multiplying by L solution on both sides of the equation. The L solution will cancel out on the right side, leaving the number of moles being equal to the molarity times volume:

Moles of solute

=Lsolution×Molarity

Now we just plug the known values in!

Moles of solute = (10.0 L) (2.0M) = 20. moles

If the user enters any operator symbol other than , -, *, or /, then an UnknownOperatorException is thrown and the user is allowed to reenter that line of input. Define the class UnknownOperatorException as a subclass of the Exception class. Your program should also handle NumberFormatException if the user enters non-numeric data for the operand.

Answers

Answer:

Explanation:

The following code is written in Java. It creates the UnknownOperatorException class and catches it if the user enters something other than the valid operators. If so it continues asking the user for a new input. Once a valid operator is entered, it exits the function and prints the operator.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       char symbol = askForOperand();

       System.out.println("Operand: " + symbol);

   }

   public static char askForOperand() {

       Scanner in = new Scanner(System.in);

       try {

           System.out.println("Enter operator symbol: ");

           char symbol = in.nextLine().charAt(0);

           if ((symbol != '-') && (symbol != '*') && (symbol != '/')) {

               System.out.println(symbol);

               throw new UnknownOperatorException();

           } else {

               return symbol;

           }

       } catch (NumberFormatException | UnknownOperatorException e) {

           System.out.println("Not a valid operand");

           char symbol = askForOperand();

           return symbol;

   }

}
