4 reasons why users attach speakers
to their computers
Answer: we connected speakers with computers for listening voices or sound because the computer has not their own speaker. the purpose of speakers is to produce audio output that can be heard by the listener. Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver.

Explanation:
Define a class Complex to represent complex numbers. All complex numbers are of the form x + yi, where x and y are real numbers, real numbers being all those numbers which are positive, negative, or zero.
Answer:
The program in C++ is as follows:
#include<bits/stdc++.h>
using namespace std;
class Complex {
public:
int rl, im;
Complex(){ }
Complex(int Real, int Imaginary){
rl = Real; im = Imaginary;
}

You will write code to manipulate strings using pointers but without using the string handling functions in string.h. Do not include string.h in your code. You will not get any points unless you use pointers throughout both parts.
You will read in two strings from a file cp4in_1.txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i] = a[i], but rather *c *a is allowed. You will not get any points unless you use pointers.

Write a program named HoursAndMinutes that declares a minutes variable to represent minutes worked on a job, and assign a value to it. Display the value in hours and minutes. For example, 197 minutes becomes 3 hours and 17 minutes.'
Answer:
Explanation:
The following code is written in Python, it asks the user for the number of minutes worked. Divides that into hours and minutes, saves the values into separate variables, and then prints the correct statement using those values. Output can be seen in the attached image below.
import math
class HoursAndMinutes:
min = input("Enter number of minutes worked: ")
hours = math.floor(int(min) / 60)
minutes = (int(min) % 60)
print(str(hours) + " hours and " + str(minutes) + " minutes")

the importance of optimizing a code
Answer:
Definition and Properties. Code optimization is any method of code modification to improve code quality and efficiency. A program may be optimized so that it becomes a smaller size, consumes less memory, executes more rapidly, or performs fewer input/output operations.
The function below takes one parameter: an integer (begin). Complete the function so that it prints every other number starting at begin down to and including 0, each on a separate line. There are two recommended approaches for this: (1) use a for loop over a range statement with a negative step value, or (2) use a while loop, printing and decrementing the value each time.
1 - def countdown_trigger (begin):
2 i = begin
3 while i < 0:
4 print(i)
5 i -= 1 Restore original file
Answer:
Follows are code to the given question:
def countdown_trigger(begin):#defining a method countdown_trigger that accepts a parameter
i = begin#defining variable that holds parameter value
while i >= 0:#defining while loop that check i value greater than equal to0
print(i)#print i value
i -= 2 # decreasing i value by 2
print(countdown_trigger(2))#calling method
Output:
2
0
None
Explanation:
In this code, a method "countdown_trigger" is declared, that accepts "begin" variable value in its parameters, and inside the method "i" declared, that holds parameters values.
By using a while loop, that checks "i" value which is greater than equal to 0, and prints "value" by decreasing a value by 2.

Which of the following is a form of media?Check all that apply.
A. a brochure distributed to many people
B. a diary
C. an email to a friend
D. a blog
Answer:
A. a brochure distributed to many people.
D. a blog.
Explanation:
Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties.
Generally, the linear model of communication comprises of four (4) main components and these are;
1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.
2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.
3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.
4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.
Hence, the following are forms of media (communication channel);
I. A brochure distributed to many people. It comprises of printed textual informations used mainly for promotional purposes.
II. A blog. It is an online website that contains both textual and multimedia messages, especially as a news platform.

What is output? public class MathRecursive { public static void myMathFunction(int a, int r, int counter) { int val; val = a*r; System.out.print(val+" "); if (counter > 4) { System.out.print("End"); } else { myMathFunction(val, r, counter + 1); } } public static void main (String [] args) { int mainNum1 = 1; int mainNum2 = 2; int ctr = 0; myMathFunction(mainNum1, mainNum2, ctr); } }
a) 2 4 8 16 32 End
b) 2 2 2 2 2
c) 2 4 8 16 32 64 End
d) 2 4 8 16 32
Answer:
The output of the program is:
2 4 8 16 32 64 End
Explanation:
See attachment for proper presentation of the program
The program uses recursion to determine its operations and outputs.
The function is defined as: myMathFunction(int a, int r, int counter)
It initially gets the following as its input from the main method
a= 1; r = 2; counter = 0
Its operation goes thus:
val = a*r; 1 * 2 = 2
Print val; Prints 2
if (counter > 4) { System.out.print("End"); } : Not true
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 2; r = 2; counter = 1
val = a*r; 2 * 2 = 4
Print val; Prints 4
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 4; r = 2; counter = 2
val = a*r; 4 * 2 = 8
Print val; Prints 8
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 8; r = 2; counter = 3
val = a*r; 8 * 2 = 16
Print val; Prints 16
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 16; r = 2; counter = 4
val = a*r; 16 * 2 = 32
Print val; Prints 32
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 32; r = 2; counter = 5
val = a*r; 32 * 2 = 64
Print val; Prints 64
if (counter > 4) { System.out.print("End"); } : True
This prints "End"
So; the output of the program is:
2 4 8 16 32 64 End
SimpleScalar is an architectural simulator which enables a study of how different pro-cessor and memory system parameters affect performance and energy efficiency.
a. True
b. False
Answer:
a. True
Explanation:
SimpleScalar refers to a computer architectural simulating software application or program which was designed and developed by Todd Austin at the University of Wisconsin, Madison, United States of America. It is an open source simulator written with "C" programming language and it's used typically for modelling virtual computer systems having a central processing unit (CPU), memory system parameters (hierarchy), and cache.
The main purpose of SimpleScalar is to avail developers or manufacturers the ability to compare two computers based on their capacities (specifications) without physically building the two computers i.e using a simulation to show or illustrate that computer B is better than computer A, without necessarily having to physically build either of the two computers.
Hence, it is an architectural simulator which makes it possible to study how different central processing units (CPUs), memory hierarchy or system parameters and cache affect the performance and energy efficiency of a computer system.
