What is one way polymorphism is implemented?


created a new class using an existing class

changing a variable from a string to a float

hiding class variables from the programs using instances of the class

repurposing an operation

Answer:

Following are the code to this question:

def combine_guest(guest1, guest2):#defining a method combine_guest that accepts two dictionary

   guest2.update (guest1)#use dictionary guest2 that use update method to update guest2 dictionary

   return guest2#return guest2 dictionary values

Rory_guest= { "Ada":2, "Ben":3, "Dav":1, "Jo":3, "Charry":2, "Terry":1, "bob":4}#defining a dictionary and add value

Taylor_guest = { "Dav":4, "Nan":1, "bobert":2, "Ada":1, "Samantha":3, "Chr":5}#defining a dictionary and add value

print(combine_guest(Rory_guest,Taylor_guest))#calling the combine_guest method

Output:

{'Nan': 1, 'Samantha': 3, 'Ada': 2, 'bob': 4, 'Terry': 1, 'Jo': 3, 'Ben': 3, 'Dav': 1, 'Charry': 2, 'bobert': 2, 'Chr': 5}

Explanation:

In the code a method, "combine_guest" is defined, that accepts two dictionaries "guest1, guest2" inside the method, in which the "guest2" dictionary uses the update method to combine the value of the guest1 dictionary and use a return keyword to return guest2 values.

In the next step, two dictionaries are declared, that holds some values and use a print method to call the "combine_guest" method and prints its return values.  

Answer:

the address of the first byte of storage.

Explanation:

If a variable uses more than one byte of memory, for pointer purposes its address is the address of the first byte of storage.

A buffer in computer technology can be defined as a temporary area set aside for data storage. Buffers reside in the random access memory (RAM). In the event that, a system process or program places more data (much more than what was originally or initially intended to be allocated for data storage) in a buffer, the extra data overflows. Consequently, this would result in having some of the data to flow into other buffers and thus, causing the data to be overwritten or corruption of the data being held in that buffer.

For instance, we can liken a buffer-overflow to pouring water (data) into a container (program memory), once it is filled the water begins to overflow as the container has reached its maximum amount.

Answer:

Catch the exception.

Explanation:

In Computer programming, an exception can be defined as an unprecedented error or event that occurs unexpectedly while a computer software application or program is running. Thus, when this exception occurs while a software program is running, it would affect its flow.

However, if the software program is able to handle and process unprecedented error or event that occured unexpectedly, it would continue to run but if it cannot handle it, the software program will force quit.

In Java programming language, exception class such as IOException, UserException, TimeoutException, and exception subclass such as CharacterCodingException, FileNotFoundException etc may be thrown when a software program encounters an unexpected error or event.

A software program that is properly coded or well-written is able to check for exceptions and appropriately handle the exceptions (unexpected errors) so as to prevent the software program from crashing or forced to quit.

This ultimately implies that, when an exception is thrown using a try clause or throw statement as it occurs, it is caught by a block of code in the software program.

Hence, if an exception is thrown, it is passed to a block of code that can catch the exception, which means to receive it in a block that can handle the problem.

Answer:

All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.

A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision

Explanation:

Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.

CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.

Answer:

B. True.

Explanation:

Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.

An incremental model refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

Hence, an incremental method typically involves developing a system through repeated cycles and smaller portions at a time, enhancing and evolving the system over time.

A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.

Hence, once you start designing the processing logic for each function of your software, you might end up throwing out your logical data model design and completely redesigning it because each function would use a specific processing logic respectively.

The complete code is as follows:

from array import *

myArr = array('f',[3, 5, 7,3, 10])

location = myArr.index(7)

print(str("7")+" is at position "+str(location+1))

Explanation:

I made corrections to the third line of the code and I added a line

This line gets the index of 7 from the array myArr using the index keyword

location = myArr.index(7)

This line prints the position of the 7 in the array

print(str("7")+" is at position "+str(location+1))

Answer:

(A) Always true

Explanation:

Given

Boolean variables x and y

Required

What is (x && y) || !(x && y)

Irrespective of what x or y is, the x && y is always true

Take for instance:

x = true;

y = true;

x&&y will also be true because the values of x and y were not altered

And this is true for whatever boolean value x or y assume

Having said that:

x&&y = true

So, the expression is analysed as follows:

(x && y) || !(x && y)

Substitute true for x&&y

(true) || !(true)

!(true) = false

So, the expression becomes:

true || false

|| represents the OR operator; and it returns true if at least one of the conditions is true.

By this:

true || false = true

Option (A) Always true answers the question.

Answer:

TreeNode minimum(TreeNode root) {

   if (root != null) {

       if (firstChild == null && nextSibling == null) {

           return root;

       } else {

           TreeNode begin = minimum(root.firstChild);

           TreeNode last = minimum(root.nextSibling);

           if (begin == false && (last == false || begin.data < last.data)) {

               return begin;

           } else {

               return last;

           }

   } else {

       return null;

   }

}

Explanation:

The Java program defines a recursive method called minimum that calls itself twice with the first and last leaf of the treenode as the respective arguments. and returns the minimum value of the treenode if the root argument is not undefined.

Printing while writing code can be useful in several ways.

One of which is to determine the progress of your code. Many a times when you write a code and some parts of your codes are not working as expected, you can use the print statement to track where the program stopped working properly.

Take for instance, you write a program of 50 lines of code and you suspect that the program stops working at line 30, you can use the print statement to track this program.

Please note that: the statement to be printed is not specific but you should make use of something unique that you can easily spot.

#include <stdio.h>

#include <math.h> /* has sin(), abs(), and fabs() */

int main(void) {

   double interval;

   int i;

   for(i = 0; i <30; i++) {

Persuasive communication is a form of interpersonal communication that aims to influence the communication partner. The primary goal of persuasive communication is to achieve changes in attitudes, but not understanding or exchanging information. Thus, basically, persuasion seeks to convince the receiver of the message of the idea emitted by the sender of the same.

In my particular case, I would like to persuade my parents to let me drive my father's car, which because it is a new car and of a quality model is restricted to me. To do this, I should use the argumentative and probative method, showing his false mistrust of me and proving that I can drive the car without problems.

The memory with variable names str1, str2, and str3 all have equal and the same value after the first if-statement.

Explanation:

The str1 was first assigned a null value while the str2 and str3 were assigned the string value "Karen" with the String class and directly respectively. On the first if-statement, the condition checks if the str1 is null and assigns the value of the variable str2 to str1, then the other conditional statement compares the values of all the string variables.

Answer:

C. 22

Explanation:

Given that the argument is being passed by value, there is no memory to consider.  So cookieJar(7) returns 7 and cookieJar(22) returns 22.

If the argument parameter was passed by reference or pointer, then perhaps the value from cookieJar(7) would be considered with cookieJar(22).

Note, this code block really isn't doing anything other than returning the value passed into it.  The "amount" variable is immediately set to 0, and then the value passed in is added to amount (which is 0), and returns.  The following code could replace this function:

public static int cookieJar(int addCookies){

return addCookies;

}

The above code will return an equivalent output to the given code.

Notice, the function is not dependent on any previous call, so the value for each is unique to the call itself, i.e., cookieJar(22) returns 22 and cookieJar(7) returns 7.

So, C. 22 would be correct.

The output for the program will be 50 with error statement is 0.50.

Program is defined as a collection of guidelines that a computer follows to carry out a certain task. Low-level access to system memory is made possible by the procedural and general-purpose nature of the C programming language. To create an executable that a computer can run, a C program needs to be run through a C compiler. A computer programmer can write lines of code that the computer can understand by utilizing a programming language to develop a program.

A & B and the variable a & b are distinct. Thus, the #main program is the only program that functions.

As a result, A = 5 and B = 10, and the answer is

A x B, which equals 5 x 10 = 50.

Thus, the output for the program will be 50 with error statement is 0.50.

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.

Spoofing can be defined as a type of cyber attack which typically involves the deceptive creation of packets from an unknown or false source (IP address), as though it is from a known and trusted source. Thus, spoofing is mainly used for the impersonation of computer systems on a network.

Hence, in spoofing internet attack, the attacker's computer assumes false internet address in order to gain access to a network.
