Answer:

You absolutely should throw an exception from a constructor if you're unable to create a valid object. This allows you to provide proper invariants in your class. ... Throw an exception if you're unable to initialize the object in the constructor, one example are illegal arguments.

Explanation:

Error codes cannot be used in constructors since they lack a return type. Therefore, throwing an exception is the most effective technique to indicate constructor failure. Here is a workaround if you don't have or are unwilling to use exceptions.

When an exception is thrown in a constructor, memory for the actual object has already been set aside before the constructor is even invoked. Therefore, after the exception is thrown, the compiler will immediately deallocate the memory the object was using.

There are two solutions to that: Simple and conventional approach: Use arrows. To make use of a two-stage construction, use a custom “construct” function after a default constructor that cannot throw exceptions.

Therefore, The constructor has the ability to “zombie” an object if it fails.

Answer:

d. Port mirror

Explanation:

Port mirroring is a method to monitor network traffic and it is used in the Intrusion Detection Systems. It is also called Switched Port Analyzer and is used to analyse the network errors. This technique basically copies the network packets and sends or transmits these copied packed from one port to another in a network device such as a switch. This means that this technique is used to copy the network packets from one switch port and send the copy of these packets to another port where these packets are monitored. This is how it analyses the network errors and incoming traffic for irregular behavior and also this can be done without affecting the normal operation of the switch and other network processes. It is simple, inexpensive and easy to establish and use. The most important advantage of using mirrored ports is that it catches the traffic on several ports at once or can capture all of the network traffic.

The correct option is (d) Use a service account and prohibit users from accessing this account for development work

Explanation:

Solution

As regards to the above requirement where the application and database server in the production environment will need to exchange the data once ever day, the following access control account practices would be used in this situation:

By making use of a service account and forbids users from having this account for development work.

The service account can be useful to explicitly issue a security context for services and thus the service can also access the local and the other resources and also prohibiting the other users to access the account for the development work.

Submitting an adhoc request daily is not a choice as this is required daily. Also, the servers can be different and cannot be put in one place. and, we cannot make use of the read-write permission to the members of that group.

Answer:

Let f be a function  

a) f(n) = n²  

b) f(n) = n/2  

c) f(n) = 0  

Explanation:  

a) f(n) = n²  

This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.  

Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:

                               f(a) = f(b) ⇒ a² = b² ⇒ a = b  

The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number.  For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.  

b) f(n) = n/2  

The above function example is an onto function because every natural number, let’s say n is a natural number that belongs to N, is the image of 2n. For example:

                               f(2n) = [2n/2] = n  

The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:  

When the value of n=1, then

                                  n/2 = [1/2] = [0.5] = 1  

When the value of n=2 then  

                                   n/2 = [2/2] = [1] = 1  

c) f(n) = 0

The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image.  The above function example is also not an onto function because every positive integer is not an image of any natural number.

Answer:

0.119

Explanation:

50 independent fair games

Mean will be 50/2 = 25

Standard deviation of the loosing probability is :

[tex]\sqrt{50*0.5*0.5}[/tex] * 10 = 33.536

we have to loose 33 times out of 50 games.

To find the approximate probability we use z- value table.

z value =  [tex]\frac{33-25}{3.35}[/tex]

z - value = 2.2659

Looking at the z-value table we get 0.119.

Answer:

In this example, the wireless router uses NAT to allocate private IP addresses to five PC's and router interface, since only one IP address is assigned or given to the wireless router by the ISP.

Explanation:

Solution

The Dynamic Host Configuration Protocol server provides the IP addresses to clients, dynamically.

Generally a wireless router contains DHCP server. a wireless router can also  assign IP addresses dynamically to its clients.

So, the wireless router assigns IP addresses to five PC's and the router interface dynamically using the DHCP.

It is stated that the Internet Service Provider (ISP) assigns only one IP address to the wireless router. Here there are five PC's and one router interface need to be allocated IP addresses.

In such cases the NAT (Network Address Translation)protocol is important and allows all the clients of the home network to sue a single internet connection (IP address) assigned or given by the ISP.

NAT permits the router to allocate the private IP addresses to client from the private IP address space reserved for the private networks. these private IP addresses are valid only in the home or local network .

   mins = 60000  # milliseconds in a minute

   secs = 1000  #milliseconds in a second

   hours =remaining / hrs  #value of millis input by user divided by 360000

   remaining %= hrs  #mod of remaining by 3600000

   minutes = remaining / mins  # the value of remaining divided by 60000

   remaining %= mins  #mod of remaining by 60000

   seconds = remaining / secs  

#the value left in remaining variable is divided by 1000

Create a Scanner object and get user entry the number of input (Line 6-7).

Use the input number as the limit to control the number of the for loop iteration to repeatedly get integer input from user (Line 9-13). Whenever user input an integer, use that integer, k, as the index to address the corresponding items in the array and increment it by one (LINE 11-12).

At last, create another for loop to iterate through each item in the array and check if there is any item with value above zero (this means with occurrence at least one). If so, print the item value as number of occurrence (Line 14-17).

Answer:

This question is answered using C++ programming language.

This program does not make use of comments; However, see explanation section for detailed line by line explanation.

The program starts here

#include <iostream>

using namespace std;

int main()

{

 double quantity,seconds;

 int minutes;

 cout<<"Quantity (mph): ";

 cin>>quantity;

 minutes = int(60/quantity);

 cout<<minutes<<" minutes and ";

 seconds = (60/quantity - int(60/quantity))*60;

 printf("%.1f", seconds);

 cout<<" seconds per mile";

 return 0;

}

Explanation:

The following line declares quantity, seconds as double datatype

 double quantity,seconds;

The following line declares minutes as integer datatype

 int minutes;

The following line prompts user for input in miles per hour

 cout<<"Quantity (mph): ";

User input is obtained using the next line

 cin>>quantity;

The next line gets the minute equivalent of user input by getting the integer division of 60 by quantity

minutes = int(60/quantity);

The next statement prints the calculated minute equivalent followed by the string " minuted and " without the quotes

 cout<<minutes<<" minutes and ";

After the minutes has been calculated; the following statement gets the remainder part; which is the seconds

 seconds = (60/quantity - int(60/quantity))*60;

The following statements rounds up seconds to 1 decimal place and prints its rounded value

 printf("%.1f", seconds);

The following statement prints "seconds per mile" without the quotes

is_prime(num)

Explanation:

This line defines the function is_prime

def is_prime(num):

The italicize line checks if the user input is 1; If yes it prints 1 is not prime

    if num == 1:

         print(str(num)+" is not prime")

If the above conditional statement is not true (i.e. if user input is greater than 1), the following is executed

    else:

The italicized checks if user input is primer (by using for loop iteration which starts from 2 and ends at the input number)

         for i in range(2 , num):

              if num % i == 0:

This line prints if the number is not a prime number and why it's not a prime number

                   print(str(num)+" is not prime because it can b divided by "+str(i)+" and "+str(int(num/i))+" with no remainder")

                   break;

If otherwise; i.e if user input is prime, the following italicized statements are executed

         else:

              print(str(num) + " is prime because only 1 and "+str(num)+" divide it with no remainder")

Explanation:

The program makes the following assumptions:

Scores between 90–100 has letter grade A

Scores between 80–89 has letter grade B

Scores between 70–79 has letter grade C

Scores between 60–69 has letter grade D

Scores between 0–69 has letter grade E

Line by Line explanation

This line defines the lettergrade functions; with two parameters (One for subject or class and the other for the score)

def lettergrade(subject,score):

This line prints the the score obtained by the student in a class (e.g. Maths Class)

     print(subject+": "+str(score))

The italicized determines the letter grade using if conditional statement

This checks if score is between 90 and 100 (inclusive); if yes, letter grade A is printed

     if score >= 90 and score <= 100:

           print("Letter Grade: A")

This checks if score is between 80 and 89 (inclusive); if yes, letter grade B is printed

     elif score >= 80 and score <= 89:

           print("Letter Grade: B")

This checks if score is between 70 and 79 (inclusive); if yes, letter grade C is printed

     elif score >= 70 and score <= 79:

           print("Letter Grade: C")

This checks if score is between 60 and 69 (inclusive); if yes, letter grade D is printed

     elif score >= 60 and score <= 69:

           print("Letter Grade: D")

This checks if score is between 0 and 59 (inclusive); if yes, letter grade F is printed

     elif score >= 0 and score <= 59:

           print("Letter Grade: F")

If input score is less than 0 or greater than 100, "Invalid Score" is printed

     else:

           print("Invalid Score")

This line prompts the user for score in Maths class

maths = int(input("Maths Score: "))

This line prompts the user for score in English class

english = int(input("English Score: "))

This line prompts the user for score in PE class

pe = int(input("PE Score: "))

This line prompts the user for score in Science class

science = int(input("Science Score: "))

This line prompts the user for score in Arts class

arts = int(input("Arts Score: "))

The next five statements is used to call the letter grade function for each class

public class Triangle

{

   //variables to hold sides of a triangle

   static double height;

   static double base;

   static double hypo;

   //method to compute hypotenuse

   static double rightTriangle(double h, double b)

   {

       return Math.sqrt(h*h + b*b);

   }

public static void main(String[] args) {

    height = 4;

    base = 3;

    hypo = rightTriangle(height, base);

 System.out.printf("The hypotenuse of the right-angled triangle is %.4f", hypo);

}

}

OUTPUT

The hypotenuse of the right-angled triangle is 5.0000

Explanation:

1. The variables to hold all the three sides of a triangle are declared as double. The variables are declared at class level and hence, declared with keyword static.

2. The method, rightTriangle() takes the height and base of a triangle and computes and returns the value of the hypotenuse. The square root of the sum of both the sides is obtained using Math.sqrt() method.

3. The method, rightTriangle(), is also declared static since it is called inside the main() method which is a static method.

4. Inside main(), the method, rightTriangle() is called and takes the height and base variables are parameters. These variables are initialized inside main().

5. The value returned by the method, rightTriangle(), is assigned to the variable, hypo.

6. The value of the hypotenuse of the triangle which is stored in the variable, hypo, is displayed to the user.

7. The value of the hypotenuse is displayed with 4 decimal places which is done using printf() method and %.4f format specifier. The number 4 can be changed to any number, depending upon the decimal places required.

8. In java, all the code is written inside a class.

9. The name of the program is same as the name of the class having the main() method.

10. The class having the main() method is declared public.

11. All the variables declared outside main() and inside another method, are local to that particular method. While the variables declared outside main() and inside class are always declared static in java.

Answer:

The Following are the outputs:

a. vroom

b. car 1

c. car 2

d. vroom

e. truck 1

f. car 2

Explanation:

The first statement System.out.println(mycar);  prints an instance of the Car object my car which calls the toString() method.

The second statement mycar.m1();  Calls the method m1() which prints car1

The third statement mycar.m2(); calls the method m2() which prints car2

Then another class is created Truck, and Truck inherits all the methods of Car since it extends Car. Truck has a method m1() which will override the inherited method m1() from the Car class.

The fourth statement System.out.println(mytruck); will print print vroom just as the first statement since it inherits that method toString()

The fifth statement calls m1() in the Truck class hence prints Truck 1

Finally the sixth statement will print car 2 because it also inherited that method and didnt overide it.

Answer:

Both b and c

Explanation:

Dotted Decimal notation is a presentation of numerical data which is expressed as decimal numbers separated by full stops. Dotted decimal notation expresses each eight bit sections of 32 bit numbers as decimal value. It provides convenient notation which is easy to understand by the people who are IT experts.

Answer:

#include <iostream>

#include <string>

using namespace std;

int main()

{

   double charge = 0.00;

   int numChars = 8;

   string color = "gold";

   string woodType = "oak";

   if(numChars > 5){

       charge += (numChars - 5) * 4;

   }

   if(woodType == "oak"){

       charge += 20;

   }

   if(color == "gold"){

       charge += 15;

   }

   charge += 35;

   cout << "The charge is: $" << charge << endl;

   return 0;

}

Explanation:

Include the string library

Initialize the variables as specified

Check if the number of characters is greater than 5 or not. If it is, add 4 to the charge for each character that is greater than 5

Check if the sign is made of oak or not. If it is, add 20 to the charge

Check if the color is gold or not. If it is, add 35 to the charge

Add the minimum cost to the charge

Print the charge

In this exercise we have to use the knowledge of the C++ language to write the code, so we have to:

The code is in the attached photo.

So to make it easier the code can be found at:

#include <iostream>

#include <string>

using namespace std;

int main()

{

  double charge = 0.00;

  int numChars = 8;

  string color = "gold";

  string woodType = "oak";

  if(numChars > 5){

      charge += (numChars - 5) * 4;

  }

  if(woodType == "oak"){

      charge += 20;

  }

  if(color == "gold"){

      charge += 15;

  }

  charge += 35;

  cout << "The charge is: $" << charge << endl;

  return 0;

}
