a. A numeric keypad.
b. An interpreter.
c. A 3D printer.
d. A speaker.
Explanation:
An output device can be defined as a hardware device that typically receives processed data from the central processing unit (CPU) and converts these data into information that can be used by the end user of a computer system.
Also, an input device can be defined as any device that is typically used for sending data to a computer system.
Generally, all of the output and input device of a computer are known as peripheral (external) devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.
Since output and input devices are peripheral (external) devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).
Some examples of peripheral (external) devices are monitor, speakers, keyboard, printer, mouse, scanner, projector etc.
Basically, the three (3) key element of a computer system are: a set of memory modules, processor and a set of input-output (I/O) modules. Each of the input-output (I/O) module interfaces to the central switch or system bus and are used to control one or more peripheral (external) devices.
a. A numeric keypad is a device used to input a PIN. It comprises of numbers ranging from 0 to 9.
b. An interpreter analyses and executes a program line by line.
c. A 3D printer produces output in the form of solid objects. It is typically used for inscribing or printing textual informations or graphic images on an object in three dimensions.
d. A speaker produces output in the form of sound. It is an electronic device that converts electrical signals into sound energy (waves).

Bugs always seem to creep into programs and code. What strategies have you learned to find bugs more easily and crush them with a fix?
Answers
The process involves in finding bugs as well as crushing them in a debugging process is extensive and this can consist of following process;
Examination of the error symptoms
identifying the cause of it
fixing of the error.
This process is usually required a large amount of work, Although no precise procedure that is set in for fixing all error, but some useful strategies that use in reducing the debugging effort.
One of the significant part of this process is localizing of the error, which is figuring out the cause as well as the symptoms. Strategies that I have learnt in finding and fixing the error in the process of debugging includes;Incremental as well as bottom-up program development; development of the program incrementally remains one of the most effective ways that can be used in localizing the error, often testing as the piece of code is added, so with this it will be easier to find the error since any error is from the last piece of code added.And also since the last fragment of the code will be small then searching for bugs won't take much time to find and debug.Bottom-up development helps in maximizing the benefits that comes from incremental development. With bottom-up development, after successful testing of a code, it's behavior will not change once another piece is added to it, since existing code will never replied on new part so it will be easier to trace error in the new code and fix it.Instrument program can be used to log information and there can be insertion of print statements.Instrument program using assertions; Assertions can be used in checking if the program actually maintains the properties or those invariant that the code relies on, Because the program will definitely stops once the assertion fails, and there is actuality that the point where the program reached and stops is closer to the cause, as well as good indicator of how the problem looks like , then the bug can then be fixed.breakpoints can be set in the program as well as stepping and over functions, then watching program expressions, as well as inspection of the memory contents at a particular point during the execution can give the needed run-time information.Backtracking: this option works in a way whereby one will need to start from the point that the problem occurred then go back through the code to to detect the issue, then the bug can then be fixed.Binary search: this is exploration of the code by using divide and conquer approach, so that the the bug be pin down quickly.Therefore, Bugs are treat to programs and they can be dealt with using discussed methods.

In this laboratory, we are going to maintain a username-password system by storing the usernames and passwords in a file. The file will consist of a single username and password per line with a space in between.
1. Begin by creating a class PasswordFile which has the following interface:
class PasswordFile
public:
PasswordFile(string filename); // opens the file and reads the names/passwords in the vectors user and password.
void addpw(string newuser, string newpassword); //this adds a new user/password to the vectors and writes the vectors to the file filename bool checkpw(string user, string passwd); // returns true if user exists and password matches
private:
string filename; // the file that contains password information
vector user; // the list of usernames
vector password; // the list of passwords
void synch(); writes the user/password vectors to the password file
The constructor accepts a filename, and reads the file one-line at a time and adds values to the vectors user and password. The function addpw adds a user/password pair to end of each vector.
2. Now create a password.txt file with some entries such as:
jsmith turtle
madams apple
Also create a main program to test your classes :
int main() PasswordFile passfile
("password.txt");
passfile.addpw("dbotting","123qwe");
passfile.addpw("egomez", "qwerty");
passfile.addpw("tongyu", "liberty");
// write some lines to see if passwords match users

a. cybersquatting
b. logic bombing
c. cyberbullying
d. bot herding
e. cyberstalking
Answers
Answer:
The correct answer is a. cybersquatting
Explanation:
Cybersquatting is the registration of a domain name that corresponds to the denomination of a brand or name, with the main objective of obtaining some economic benefit from its sale to the owner and legitimate owner of the brand. Cybersquatting can range from making money by parking domains (buying names that are then "parked", that is, left unused but generating advertising revenue based on the visits they receive) to redirecting users to another website In order for it to get more traffic, that is, with cybersquatting it is generally intended to sell the registered domain names to the legitimate owners or interested parties, at a price well above the cost of registration or also to use the domain taking advantage of the recognition associated with the legitimate owner to obtain commercial advantages, as clients in the network.
It is desired to create a mortgage estimator by writing a program containing a function. The user inputs the amount of loan (L), the loan term in number of months (W, and the annual interest rate (D in the script. The script then makes use of a function that accepts these values as inputs through its argument and calculates and returns the monthly payment and the total payments over the life of the loan. The monthly payment and the total payment could be calculated using the following expressions:
monthly payment 1-(1+ 1 112) N I/12 total payment Nxmonthly payment
Note that the interest rate must be expressed in decimal; for example, if the interest rate is 8% it must be entered as 0.08 Test your program for several scenarios and submit the results with the program listing.
The values of L, I, monthly payment, and total payment should be written to a file as shown below:
Interest Loan Amount Interest Months Monthly Payment Total Payment
0.06 10000 36
108 120000 0.05
0.07 85000 48
0.08 257000 240
0.05 320000 120
Answers
Answer:
In Python:
L = int(input("Loan Amount: "))
N = int(input("Months: "))
I = float(input("Annual Interest Rate: "))
monthly_payment = round(L/((1 - (1 + I/12)**(-N))/(I/12)),2)
total_payment = round(N * monthly_payment,2)
f= open("outputfile.txt","a+")
f.write(str(L)+"\t\t"+str(I)+"\t\t"+str(N)+"\t\t"+str(monthly_payment)+"\t\t"+str(total_payment)+"\n")
Explanation:
The next three lines get the required inputs
L = int(input("Loan Amount: "))
N = int(input("Months: "))
I = float(input("Annual Interest Rate: "))
Calculate the monthly payment
monthly_payment = round(L/((1 - (1 + I/12)**(-N))/(I/12)),2)
Calculate the total payment
total_payment = round(N * monthly_payment,2)
Open the output file
f= open("outputfile.txt","a+")
Write output to file
f.write(str(L)+"\t\t"+str(I)+"\t\t"+str(N)+"\t\t"+str(monthly_payment)+"\t\t"+str(total_payment)+"\n")

Write a program that picks up a secret number from 1 to 100 when the user starts the game and asks the
user to guess what number it is. If the user’s guess is correct, the program congratulates the user for the
perfect answer and then make it possible for the user to start a new game; otherwise, it will tell the user
that it is too high or too low and let the user continue to play.
In your program, you may use the following code to generate a random number from 1 to 100 as the
secret number for a new game.
import random
number = random.randint(1, 100)
In addition, your program will keep track of the number of guesses the user made and display the number
of guesses when a game is over. If a user is successful by more than 7 tries, display an additional message
to tell the user to consider a different strategy in order to improve one’s performance.
Given below is a typical dialog between a user and your program when the user uses your program.
Hello, what is your name? John
John, I am thinking a number between 1 and 100 (both included).
Can you guess what it is?
Guess a number (1-100): 50
Your guess is too high. Try again.
Guess a number (1-100): 25
Your guess is too low. Try again.
Guess a number (1-100): 35
Your guess is too low. Try again.
Guess a number (1-100): 43
John, you won in 4 tries. Congratulations!
Do you want to continue to play? no
Thank you for playing this game. Bye.
In the above, the user plays the game only once. If the user says ‘yes’ at the second to last step, he/she
would be able to play the game again.

RequireD:
Write a recursive function that takes as its argument the height of a pyramid of cannonballs and returns the number of cannonballs it contains.
Answers
Answer:
The function in C is as follows:
#include <stdio.h>
int C_ball(int height){
if(height == 1) {
return 1;}
return (height * height) + C_ball(height - 1);}
int main(){
int n;
printf("Height: ");
scanf("%d",&n);
printf("Balls: %d",C_ball(n));
return 0;

Explanation:
The function begins here
#include <stdio.h>
This defines the function
int C_ball(int height){
If height is 1, return 1
if(height == 1) {
return 1;}
This calls the function recursively
return (height * height) + C_ball(height - 1);}
The main begins here
int main(){
This declares the height as integer
int n;
This prompts the user for the height
printf("Height: ");
scanf("%d",&n);
This calls the function
