Answer:

In Java:

import java.util.*;

public class Main{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int n;

System.out.print("Max of series: ");

n = input.nextInt();

for(int i = 1; i<=n;i+=4){

System.out.print(i+" ");

}

Explanation:

This declares n as integer. n represents the maximum of the series

int n;

This prompts the user for maximum of the series

System.out.print("Max of series: ");

This gets user input for n

n = input.nextInt();

The following iteration prints from 1 to n, with an increment of 4

for(int i = 1; i<=n;i+=4){

System.out.print(i+" ");

}

Which of the following is not an Error Style for data validation?

Brut [27]

Based on the Microsoft Excel data validation, the option that is not an Error Style for data validation is the choice that does not show an error alert.

Given that there is no option available, the best way to answer this question is to show the types of Error Styles for data validation available.

<h3>Different types of Error Style for data validation</h3>

Stop style: this will bring the option of "Retry, " "Cancel, " and "Help."

Warning style: this will show "Continue," with options of "Yes," "No," "Cancel," and "Help."

Information Style: this will ask you to input the whole number with the option of "Ok," "Cancel," and "Help."

Hence, in this case, it is concluded that the Error Style for data validation is Stop, Warning, and Information Style.

Answer:

Check the explanation

Explanation:

//Bugs are highlighted in bold text

class Invoice

Declarations

private num invoiceNumber

private string customer

private num balanceDue

private num tax

public void setInvoiceNUMBER(num number)

Declarations

num LOW_NUM = 1000

num HIGH_NUM = 9999

if number > HIGH_NUM then

invoiceNumber = 0

else

if number < LOW_NUM then

invoiceNumber = 0

else

invoiceNumber = num

endif

return

public void setCustomer(string cust)

customer = cust

return

public void setBalanceDue(num balance)

//Bug balanceDue is Invoice class varible

//but it is assigned to balance .it gives error

balance = balanceDue

setTax()

return

private void setTax()

Declarations

//Bug TAX_RATE is declared as string

//but assigned a double value

string TAX_RATE = 0.07

tax = tax * TAX_RATE

return

public void displayInvoice()

output "Invoice #", invoiceNumber

output "Customer: ", customer

output "Due: ", balanceDue

output "Tax: ", taxDue

//Bug

//Invoice class has no variable called balance .it should be balanceDue

output "Total ", balance + taxDue

return

endClass

start

Declarations

Invoice inv1

Invoice inv2

//Warning

//it gives warning object taken but not initilaized

//Bug

//setTax method of Invioce doesnot take any arguments

inv3.setTax(210.00)

inv3.displayInvoice()

stop

//Here is the complete program in c++

Which option ie an example of an html end tag

Kay [80]

Any end tag in HTML needs to look like this, the word body used in this example is one of the more important elements, but you can replace it to any real element in HTML:
