5)What are the differences in the function calls between the four member functions of the Shape class below?void Shape::member(Shape s1, Shape s2);void Shape::member(Shape *s1, Shape *s2);void Shape::member(Shape& s1, Shape& s2) const;void Shape::member(const Shape& s1, const Shape& s2);void Shape::member(const Shape& s1, const Shape& s2) const;
Answer:
void Shape :: member ( Shape s1, Shape s2 ) ; // pass by value
void Shape :: member ( Shape *s1, Shape *s2 ) ; // pass by pointer
void Shape :: member ( Shape& s1, Shape& s2 ) const ; // pass by reference
void Shape :: member ( const Shape& s1, const Shape& s2 ) ; // pass by const reference
void Shape :: member ( const Shape& s1, const Shape& s2 ) const ; // plus the function is const
Explanation:
void Shape :: member ( Shape s1, Shape s2 ) ; // pass by value
The s1 and s2 objects are passed by value as there is no * or & sign with them. If any change is made to s1 or s2 object, there will not be any change to the original object.
void Shape :: member ( Shape *s1, Shape *s2 ) ; // pass by pointer
The s1 and s2 objects are passed by pointer as there is a * sign and not & sign with them. If any change is made to s1 or s2 object, there will be a change to the original object.
void Shape :: member ( Shape& s1, Shape& s2 ) const ; // pass by reference
The s1 and s2 objects are passed by reference as there is a & sign and not * sign with them. If any change is made to s1 or s2 object.
void Shape :: member ( const Shape& s1, const Shape& s2 ) ; // pass by const reference
The s1 and s2 objects are passed by reference as there is a & sign and not * sign with them. The major change is the usage of const keyword here. Const keyword restricts us so we cannot make any change to s1 or s2 object.
void Shape :: member ( const Shape& s1, const Shape& s2 ) const ; // plus the function is const
The s1 and s2 objects are passed by reference as there is a & sign and not * sign with them. const keyword restricts us so we cannot make any change to s1 or s2 object as well as the Shape function itself.

Explanation:
A network is the interconnection and communication of two or more computer devices. Computer systems on a network shares resources with one another, using network standards like OSI and TCP/IP suite model and using the protocols on each layers.
There are two major types of network communication between devices and they are peer to peer or point to point Network and client-server network.
Point to point Network uses one secure physical link to connect two computers or routers in a network.
Convert the value of the following binary numbers to hexadecimal notation. (Note: this question has 2 parts; you must answer each part correctly to receive full marks. Do not include spaces, commas or subscripts in your answer.)
a. 11012 =
b. 111011102 =
Answer:
Explanation: Where binary numbers are made up of 0s and 1s, numbers in hexadecimal (base 16) contains digits from 0 to 9 as well as letters from A to F. Any number gotten from applying the placeholders (8,4,2,1) that is above 9 is changed into letters. Thus: 10 = A; 11 = B; 12 = C; 13 = D; 14 = E & 15 = F
Solving the question, we split the binaries groups of fours while adding 0s from the left hand side of incomplete groups of four to make it up to four.
I would place the placeholders in brackets for example 1(8) should be read as "number of 8s is 1; 0(2) as " number of 2s is 0"
1. 1101 in base to to base 16 = 1(8) 1(4) 0(2) 1(1)
= 8 + 4 + 0 + 1 = 13 = D
Therefore, 1101 base 2 is D in hexadecimal
2. 11101110 = 1110 & 1110 {group of four}
1110 = 1(8) 1(4) 1(2) 0(1)
= 8 + 4 + 2 + 0 = 14 = E
Therefore, 11101110 base 2 = EE in hexadecimal
Explain why deploying software as a service can reduce the IT support costs for a company. What additional costs might arise if this deployment model is used?
Answer:
It reduces the cost of multiple subscription, but the cost of management is applied.
Explanation:
Cloud computing is the use of online resources like storage infrastructure available on database servers to hold company resources on a central level. There are various platforms available in adopting cloud services and they are SaaS or software as a service, PaaS, or platform as a service, IaaS or infrastructure as a service etc.
SaaS is a cloud computing services where software applications are made centrally available for an organisation. It reduces the cost of purchasing multiple activation keys for software traditionally installed. But it requires a skilled personnel and annual or monthly subscription, which when added together, might spike the cost of deployment.
1. Write an expression whose value is the result of converting the str value associated with s to an int value. So if s were associated with "41" then the resulting int would be 41.2. Write an expression whose value is the last character in the str associated with s.
3. Given variables first and last, each of which is associated with a str, representing a first and a last name, respectively. Write an expression whose value is a str that is a full name of the form "Last, First". So, if first were associated with "alan" and last with "turing", then your expression would be "Turing,Alan". (Note the capitalization! Note: no spaces!) And if first and last were "Florean" and "fortescue" respectively, then your expression’s value would be "Fortescue,Florean".
4. Write an expression whose value is the result of converting the int value associated with x to a str. So if 582 was the int associated with x you would be converting it to the str "582".

Implement the function calcWordFrequencies() that uses a single prompt to read a list of words (separated by spaces). Then, the function outputs those words and their frequencies to the console.
Ex: If the prompt input is:
hey hi Mark hi mark
the console output is:
hey 1
hi 2
Mark 1
hi 2
mark 1
Final answer:
The function calcWordFrequencies prompts for input, splits the input into words, counts their occurrences using an object, and logs each word along with its frequency to the console.
Explanation:
To implement the function calcWordFrequencies that reads a list of words separated by spaces and outputs their frequencies, you can use a programming language like JavaScript. The function will prompt the user for input, then split the input string by spaces to get an array of words. After that, the function will count the occurrences of each word using an object to store the frequencies, and finally, it will log the words and their respective frequencies to the console.
Here is an example of how this function might look:
function calcWordFrequencies() {
var input = prompt('Enter a list of words separated by spaces:');
var words = input.split(' ');
var frequencies = {};
for (var i = 0; i < words.length; i++) {
var word = words[i].toLowerCase();
frequencies[word] = (frequencies[word] || 0) + 1;
}
for (var word in frequencies) {
console.log(word + ' ' + frequencies[word]);
}
}
Note: The example above converts all words to lowercase to count 'Mark' and 'mark' as two occurrences of the same word. You can remove the toLowerCase call if you want to distinguish between capitalized and lowercase words.
Final answer:
To count word frequencies in Python, use the input() function to collect user input, split the input into words, use a dictionary to track frequencies, then iterate and print each word with its frequency.
Explanation:
To implement the function calcWordFrequencies that reads a list of words from the user and outputs the frequency of each word, you can follow these steps in Python:
Use the input() function to prompt the user to enter a list of words separated by spaces.Create an empty dictionary to keep track of word frequencies.Split the input string into words using the split() method.Iterate over the list of words and for each word: If the word is already in the dictionary, increment its frequency.If the word is not in the dictionary, add it with a frequency of 1.Iterate over the dictionary and print each word along with its frequency.Here is an example code snippet that demonstrates these steps:
def calcWordFrequencies():Write pseudocode to represent the logic of a program that allows a user to enter three values then outputs the product of the three values. (If you're not sure of the definition of product be sure to look it up to verify its meaning.)
Final answer:
The pseudocode for a program that outputs the product of three user-entered values involves prompting the user for each value, calculating the product by multiplication, and displaying the result.
Explanation:
Writing Pseudocode for a Multiplication Program
The task is to write pseudocode that represents the logic of a program allowing a user to enter three values and then outputs the product of these values. The product refers to the result of multiplying the three numbers together. Below is the pseudocode for accomplishing this task:
START
Prompt user to enter the first value
Read firstValue
Prompt user to enter the second value
Read secondValue
Prompt user to enter the third value
Read thirdValue
Set product to firstValue multiplied by secondValue multiplied by thirdValue
Output product
END
This simple algorithm prompts the user to input three separate values and calculates the product by multiplying them together. The result is then displayed to the user.
Final answer:
The pseudocode for calculating the product of three user-entered values consists of reading the values, computing the product, and outputting the result.
Explanation:
The student is asking for pseudocode to calculate the product of three values entered by the user. Pseudocode is an informal way of programming description that does not require any strict programming language syntax, yet it describes the logic of the algorithm clearly. Below is an example of how this pseudocode might look:
START
Prompt user for first value
Read value1
Prompt user for second value
Read value2
Prompt user for third value
Read value3
Set product = value1 * value2 * value3
Output product
END
This pseudocode begins by prompting the user to enter three values. It then reads the values into three variables, calculates the product of these values by multiplying them, and finally outputs the product.
If you hear that an airplane crashes into the Empire State Building, and you immediately think of the 9/11 terrorist attack on the World Trade Center, you are reacting to what type of memory? a repressed memory a suppressed memory a flashbulb memory a pseudo-memory
Final answer:
If you think of the 9/11 terrorist attack when hearing about an airplane crashing into the Empire State Building, you are reacting to a flashbulb memory.
Explanation:
If you hear that an airplane crashed into the Empire State Building and immediately think of the 9/11 terrorist attack on the World Trade Center, you are reacting to a memory known as flashbulb memory. A flashbulb memory is an exceptionally clear recollection of an important and emotionally charged event.
Thus, a flashbulb memory is a vivid, detailed, and long-lasting recollection of the circumstances surrounding a significant, emotionally charged event. Many people remember exactly where they were and how they heard about significant events like 9/11, even years later. These memories can be vivid and distinct, often accompanied by strong emotions.
The type of memory you are experiencing is called a flashbulb memory so the correct option is C. a flashbulb memory.
If you hear that an airplane crashes into the Empire State Building and immediately think of the 9/11 terrorist attack on the World Trade Center, you are reacting to a flashbulb memory.

In C#Write the program SubscriptExceptionTest in which you use an array of 10 doubles. Write a try block in which you place a loop that prompts the user for a subscript value and displays the value stored in the corresponding array position or asks the user to quit the program by entering 99. Create a catch block that catches any IndexOutOfRangeException and displays the message: Index was outside the bounds of the array.
Answer:
using System;
namespace ConsoleApp3
{
class Program
{
static void Main(string[] args)
{
double[] doubleArray = { 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0 };
Console.WriteLine("Double Array values are:");
foreach (var b in doubleArray)
{
Console.WriteLine(b);
}
Console.WriteLine("Enter value to find position in Array");
var input = Console.ReadLine();
var value = Convert.ToDouble(input);
if (value == 99.0)
{
Environment.Exit(0);
}
try
{
var index = Array.IndexOf(doubleArray, value);
if (index == -1)
{
Console.WriteLine("Index was outside the bounds of the array");
Console.ReadLine();
}
else
{
Console.WriteLine("Position in Array is:" + index);
Console.ReadLine();
}
}
catch (Exception e)
{
Console.WriteLine("Index was outside the bounds of the array");
Console.ReadLine();
}
}
}
}
Explanation:
this is the code of console program which initialize the double array from 1-10 and displays the existing values of array in console.
Then it will take input from user, convert it to double and find the value position in double array.
if 99, then program will be exist
if exist in array:display the index position
else:index was outside the bounds of the array in try catch block.

Universal Containers has a monthly accounts receivable report that compiles data from Accounts, Contacts, Opportunities, Orders. and Order Line Items. What difficulty will an architect run into when implementing this in Salesforce?
Answer:
There are four options for this question, A is correct.
A. Salesforce allows up to four objects in a single report type.
B. Salesforce does not support orders or orders line items.
C. A report cannot contain data from accounts and contacts.
D. Custom report types cannot contain opportunity data.
Explanation:
The Salesforce doesn't permit adding more than four objects if the user tries to add more than this limit, the user will receive an error message, this would be the main problem for an architect run into when implementing this in Salesforce, some reports need more data and with this limit is hard to do the reports.
Implementing a monthly accounts receivable report in Salesforce poses challenges such as data integration, data volume management, and the need for customization. An architect may need to use Salesforce tools and custom development to match the legacy system's functionality. Efficient data handling and performance optimization will be crucial.
Challenges in Implementing a Monthly Accounts Receivable Report in Salesforce
When transitioning a monthly accounts receivable report from a legacy system to Salesforce, an architect may encounter several difficulties:
Data Integration: Aligning data from multiple objects like Accounts, Contacts, Opportunities, Orders, and Order Line Items can be complex due to differences in data models and relationships.Data Volume: Handling large volumes of data in Salesforce might require optimization techniques like indexing, batch processing, and efficient querying to ensure the report performs well.Customization: Salesforce might need custom development using Apex or Visualforce to replicate specific functionalities and formats present in the legacy report.Reporting Tools: Utilizing Salesforce reporting tools effectively, such as custom report types and dashboards, will be essential but might not fully replace the flexibility of the legacy system's reporting capabilities without additional customization.Examples and Solutions
For example, integrating Order Line Items with related Opportunities might involve creating custom report types that relate these objects. Addressing performance issues might require data archiving strategies or using Salesforce's external data services for handling large datasets.
Consider a system that contains 32K bytes. Assume we are using byte addressing, that is assume that each byte will need to have its own address, and therefore we will need 32K different addresses. For convenience, all addresses will have the same number n , of bits, and n should be as small as possible. What is the value of n ?
Answer:
n = 15
Explanation:
Using
Given
Number of bytes = 32k
At the smallest scale in the computer, information is stored as bits and bytes.
In the cases when used to describe data storage bits/bytes are calculated as follows:
Number of bytes when n = 1 is 2¹ = 2 bytes
When n = 2, number of bytes = 2² = 4 bytes
n = 3, number of bytes = 2³ = 8 bytes
So, the general formula is
Number of bytes = 2^n
In this case
2^n = 32k
Note that 1k = 1024 bytes,
So, 32k = 32 * 1024 bytes
Thus, 2^n = 32 * 1024
2^n = 2^5 * 2^10
2^n = 2^15
n = 15.
Final answer:
To address 32K bytes uniquely using byte addressing, 15 bits are required which [tex]2^{15}[/tex] equals 32768, the number of bytes in 32K. This demonstrates a fundamental concept of how memory is addressed in computing.
Explanation:
Understanding the minimum number of bits required to represent a certain amount of memory is a fundamental concept in computer science. To represent 32K bytes where 'K' stands for kilo (1024) due to binary base, we need to calculate the minimum number of bits (n) to address each byte. Essentially, 32K bytes equals 32 * 1024 = 32768 bytes. The question is how many bits are required to uniquely address each of these bytes.
To find the value of n, we rely on the principle that each bit can represent 2 states. Therefore, [tex]2^{n}[/tex] should be equal to or greater than 32768. Calculating this, we see that [tex]2^{15}[/tex] = 32768 exactly, indicating that 15 bits are sufficient to address 32K bytes uniquely. Thus, n = 15.
This example highlights how binary representation and addressing work in computing, illustrating why understanding of binary and byte addressing is crucial in fields related to computers and technology.

ETL or extract-transform-load is very important for the successful implementation of data warehousing
A 1 MB digital file needs to transmit a channel with bandwidth of 10 MHz and the SNR is 10 dB. What is the minimum amount of time required for the file to be completely transferred to the destination?
Answer:
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.
Explanation:
We can calculate the channel capacity using Shannon's Capacity formula:
C = B + log₂ (1 + SNR)
Where C = Channel Capacity
B = Bandwidth of the Channel
SNR = Signal to Noise Ratio
We are given SNR in dB so we need to convert it into a ratio.
[tex]SNR_{dB}[/tex] = 10log₁₀ (SNR)
10 = 10log₁₀ (SNR)
1 = log₁₀ (SNR)
SNR = 10¹
SNR = 10
So, using Shannon Channel Capacity formula:
C = 10 x 10⁶ log₂ (1 + 10)
C = 34.5 MHz
Total amount of time required to transmit a 1MB file:
1MB = 1 x 8 Mbytes = 8Mb
C = 34.5 MHz = 34.5 Mb/s
Time required = 8Mb/34.5Mb/s = 0.23 seconds
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.

Answer:
Hi there! This question is good to check your knowledge of entities and their relationships. The diagram and explanation are provided below.
Explanation:
The entity relationship diagram for the association between the entities according to the description in the question is drawn in the first attachment. We can further simplify the relationship by removing this many to many relationship between "Chemists" and "Projects" by adding another entity called "Worklist" as detailed in second attachment.
in a multitasking system, the context-switch time is 1ms and the time slice is 10ms. Will the CPU efficiency increase or decrease when we increase the time slice to 15ms? Explain why.
Answer:
Answer explained below
Explanation:
It depends on the arrival time and burst time of the processes. On increasing the time slice the waiting and turn around time can increase and decrease both.
As waiting time and turn around time are the major criteria for calculating the efficiency, so we can't say whether the efficiency will increase or decrease.
Write a function solution that returns an arbitrary integer which is greater than n.
Answer:
public static int greaterThanInt(int n){
return n+10;
}
Explanation:
This is a very simple method in Java. it will accept an argument which is an integer n and return n+10 since the question requires that an arbitrary integer greater than n be returned adding any int value to n will make it greater than n.
A complete java program calling the method is given below:
import java.util.Scanner;
public class ANot {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Please enter an integer");
int n = in.nextInt();
int greaterInt = greaterThanInt(n);
System.out.println("You entered "+n+", "+greaterInt+" is larger than it");
}
public static int greaterThanInt(int n){
return n+10;
}
}
Some architectures support the ‘memory indirect’ addressing mode. Below is an example. In this case, the register R2contains a pointer to a pointer. Two memory accesses are required to load the data. ADD R3, @(R2)The MIPS CPU doesn’t support this addressing mode. Write a MIPS code that’s equivalent to the instruction above. The pointer-to-pointer is in register $t1. The other data is in register $t4.
