Consider the following general code for allowing access to a resource:
Margaret [11]

Answer:

a) The code allows access even when  IsAccessAllowed(...) method fails.

b) Either use If

(dwRet = ACCESS_ALLOWED)

or use

if (dwRet == NO_ERROR)

to avoid flaw

Explanation:

Lets first see what the code chunk does:

DWORD dwRet = IsAccessAllowed(...);

if (dwRet == ERROR_ACCESS_DENIED) {

// Security check failed.

// Inform user that access is denied.

} else {

// Security check OK.

}

In the given code, DWORD is basically a data type for double word type integers and this is defined in windows.h

So there is DWORD type variable dwRet that is assigned a method calls.

The method is IsAccessAllowed() which checks if the access is allowed to user.

if (dwRet == ERROR_ACCESS_DENIED) condition basically checks if the value of DWORD type variable dwRet is equal to ERROR_ACCESS_DENIED

If this condition evaluates to true then the security checks fails and user is informed via some message or action that the access is denied.  But when the if condition evaluates to false then the else part executes which allows access.

So basically this chunk of code checks if the error ERROR_ACCESS_DENIED is returned.

Now the flaw in this program is what if the method IsAccessAllowed() by any reason. The reasons can be system failure or the memory failure. In memory failure case for example, the system returns out of memory error. So this means that the error is not  ERROR_ACCESS_DENIED. Instead it is out of memory error. So in such a case the user is allowed access as the if condition evaluates to false and else part executes. So if any other error is produced due to some reason like mentioned above, then user has unrestricted access.

This shows that the doe should not check for the failure or rely on checking ERROR_ACCESS_DENIED to allow access but instead it should check for success. Code should only give access privilege if access is allowed successfully or no error is produced.

So to avoid this flaw the code is altered as:

DWORD dwRet = IsAccessAllowed(...);

If (dwRet = ACCESS_ALLOWED) {

//Security check OK.

} else {

//Security check failed.

//Inform user that access is denied.

}

This will only allow access if ACCESS_ALLOWED evaluates to true and success is checked instead of failure here

You can also alter the if condition as:

If (dwRet = No_Error)

or

If (dwRet = 0)

The above if conditions checks if the access is allowed or if no error is produced. Only then it will allowed access otherwise not. So the access check is a success is checked first and failure (for any reason). The user is allowed access only if there is no error otherwise user is not allowed access.

If you are referencing cell (C2)in Excel and want to be able to copy the formula and keep using the data in cell C2 in every place you copy it to, the way to reference the cell? is known to be $C$2.

<h3>What is a cell reference in Excel?</h3>

A cell reference is known to be called a cell address and this is seen as a make up of a column letter and also those of  row number that tells a cell on a worksheet.

One lap around a standard high-school running track is exactly 0.25 miles. Write a program that takes a number of miles as input
salantis [7]

Answer:

import java.util.Scanner;

public class Miles {

public static void main(String[] args) {

   //initialization

       double Number_Miles;

       //print the message

       System.out.print("Enter the number of miles: ");

       Scanner scn1 = new Scanner(System.in);

       

       Number_Miles = scn1.nextDouble();  //read the input from user

       //calculate the laps

       double yourValue = Number_Miles/0.25;

       //display the output on the screen

       System.out.printf("%.2f", yourValue);

     

}

}  

Explanation:

First import the library Scanner than create the class and define the main function. In the main function, declare the variables.

print the message on the screen and then store the value enter by the user into the variable.

Scanner is a class that is used for reading the output. So, we make the object of the class Scanner and then object call the function nextDouble() which reads the input and store in the variable.

After that, calculate the number of laps by dividing the number of miles with the given one lap running track value (0.25 miles).

Number\,of\,laps = \frac{Number\,of\,miles}{0.25}

the output is stored in the variable.

After that, print the value on the screen with 2 digits after the decimal point.

we can use "%.2f" in the printing function in java.

like System.out.printf("%.2f", output);
