Final answer:
To solve the programming exercise, include cin to read two strings representing the first and last name, then output them in 'Last name, First name' format using cout, followed by a newline.
Explanation:
To complete the coding exercise, you need to read in a person's first and last name and then display the last name followed by a comma, and then the first name. You can achieve this by using the cin to read the names and cout to output the result in the required format.
The program will look like this:
#include
#include
using namespace std;
int main() {
string firstName;
string lastName;
// Reading the first and last name
cin >> firstName >> lastName;
// Output in 'Last name, First name' format
cout << lastName << ", " << firstName << endl;
return 0;
}
Simply include the code segment within the "/* Your solution goes here */" section in your program. When you run this code, it will prompt you to input a first and last name, and after you provide it, the program will print out the last name, a comma, and then the first name followed by a newline as specified in the exercise.
Discuss the type of noise that is the most difficult to remove from an analog and a digital signal? Give reasons for your answer. How does error detection and correction work with wireless signals? Is data compressed when being transmitted? Describe the process.
Answer:
Explanation: One of the noise difficult to remove is "Flicker noise". This noise is a 1/f power spectral density that occurs in almost all electronic devices, which increases the overall noise level. It also shows up with variety of other effects, such impurities in conductive channels of electronic components.
Error detection and correction in wireless signals work by modulating the carrier signals of a waveform through radio transmission.
Data is not compressed when transmitted, rather data is broken into fragments known as packets and transmitted by method of packet switched networking and applying a protocol called "Transmission control protocol".
Final answer:
The answer discusses the challenges of removing noise from analog and digital signals, error detection and correction with wireless signals, and the data compression process.
Explanation:
Analog vs. Digital Signal Noise
Most Difficult Noise to Remove: The most challenging noise to remove from an analog signal is cumulative noise that builds up with each copy due to continuous variability. In digital signals, noise is less problematic as it can be regenerated and removed.
Error Detection and Correction with Wireless Signals: Error detection and correction in wireless signals involve adding redundant data to check for errors and correct them if detected.
Data Compression Process: Data is compressed before transmission by reducing redundant information, utilizing encoding schemes like lossless or lossy compression.
How is the security of a firm's information system and data affected by its people, organization, and technology? Is the contribution of one of these dimensions any more important than the other? Why?
Explanation:
What happens is that the security of a company's information and data system can be affected by its people because it is the organization's own employees who can leak sensitive information, for their own benefit or for the benefit of others. That is why it is extremely relevant that organizations should limit the level of access that each user has to their information system.
Adequate training in the use of these systems is essential for employees to use it properly, to correct system failures, and for top management to have adequate knowledge in the preparation of system security plans.
It is the security policies that will prevent unauthorized access and greater control over the security of important data and information, so it is important that any company with a data information system keeps itself up to date with the software and implements necessary security resources, in a way maintain security and always update and analyze the operation of technological equipment.
Discuss how a router knows where to send a message and then any experience you might have setting one up. In your opinion what are the challenges in establishing a network connection between two points over a large distance? Describe your own knowledge of this network configuration.
Answer:
Routing table and routing table population.
Explanation:
A router is an intermediate network device used to determine a good path for routing packets. It is a layer 3 device. Each interface of the router is a broadcast domain, that is, it represents a network.
It uses its routing table to find paths to a network. The router's routing table can populated (to add more routes) statically and dynamically.
To populate a routing table statically, use the format, "IP rout 'network address' 'subnet mask' 'next hop address'".
To populate dynamically, the protocols like RIP, OSPF, BGP, EIGRP etc, are used. The static routing is good for small networks because routing table population is manual while dynamic routing is good for large networks because it's routing table population is automatic.
In this assignment you will implement a class called "string_class". Place the class declaration in the file "string_class.h" and the class implementation in the file "string_class.cpp". The class has the following characteristics"
1. A private string variable "current_string".
2. A default constructor that sets "current_string" to an empty string ("").
3. An explicit-value constructor that sets "current_string" equal to the argument that is passed to the explicit-value constructor when a string_class object is declared.
4. A public member Boolean function called "palindrome" that returns true if the current_string reads the same forward asit does backwards; otherwise it return false. For example "madam", "463364", and "ABLE WAS I ERE I SAW ELBA" are all palindromes.
5. A public member string function called "replace_all" that accepts two string arguments, " old_substring" and "new_substring". The function will return a copy of the string "current_string" with each occurrenceof "old_substring" replacedby "new_substring". For example, when the function is invoked, if current_string = "aaabbacceeaaa", old_substring = "aa", and new_substring= "zzz", then after execution of the function, current_string = "zzzabbacceezzza", and the function will return "zzzabbacceezzza". NOTE: DO NOT USE THE STRING CLASS FUNCTIONS "find", "replace", or "substr".
6. Overload the insertion operator (<<) as a friend function of the class with chaining to print the contents of a string_class object’s "current_string".
7. You make implement other class member functions if necessary

Group of answer choices True False
Answer:
True
Explanation:
OOP or object oriented programming is a structured programming process that relates or classify data into fields. It is based on creating objects with available data.
OOP deals with classes and objects. Classes are containers or a defined collection of objects. Objects are collections of data that identifies that object.
An example of class and object is man and John, where man is the class and John, the object.
There can only be one version of the class "man" in the program.
A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow.Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name.
Final answer:
The student's question is about creating a Python program to map names to phone numbers using a dictionary, where after inputting contacts, the program can search for and retrieve phone numbers by name.
Explanation:
The student's question involves writing a program to manage a list of contacts, specifically to map names to phone numbers. To solve this task, one would typically use a data structure known as a dictionary in programming, where each name (key) is associated with a corresponding phone number (value). Below is a simple example of how one could write such a program in Python:
# Prompt for the number of contacts
N = int(input('Enter the number of contacts: '))
# Initialize an empty dictionary to store contacts
contacts = {}
# Loop to enter the contacts into the dictionary
for _ in range(N):
name, phone_number = input('Enter contact name and phone number: ').split()
contacts[name] = phone_number
# Prompt for the name to search
search_name = input('Enter a name to search for their phone number: ')
# Output the phone number for the given name
if search_name in contacts:
print(f'The phone number for {search_name} is {contacts[search_name]}')
else:
print('Name not found in contact list.')
This script takes the number of contacts as input, then iterates and adds each name-phone pair to the contacts dictionary. When the user enters a name to search, the program looks up the name in the dictionary and prints out the associated phone number if found.
n the case of the sentinel-controlled while loop, the first item is read before the while loop is entered. True False

Write a function call it isEvenPositiveInt which takes an integer x and return true if x is positive and also even. Note isinstance(x, int) will return True if x is an integer
So
>>> isinstance (23, int)
True
>>> isinstance (12.34, int)
False
>>> isinstance (12.34, float)
True
Answer:
The program to this question as follows:
Program:
def isEvenPositiveInt(x): #defining method isEvenPositiveInt
if x>0: #checking number is positive or not
if x%2==0: #check true condition
return True #return value True
else:
return False #return value False
return False #return value False
print(isEvenPositiveInt(24)) #calling method and print return value
print(isEvenPositiveInt(-24)) #calling method and print return value
print(isEvenPositiveInt(23)) #calling method and print return value
Output:
True
False
False
Explanation:
In the above Python program, a method "isEvenPositiveInt" is defined, that accepts a variable "x" as its parameter, inside the method a conditional statement is used, which can be described as follows:
In the if block the condition "x>0" is passed, that check value is positive, if this condition is true, it will go to another if block. In another, if block is defined, that checks the inserted value is even or not, if the value is even it will return "true", otherwise it will go to the else part, that returns "false".Write a program that converts grams to pounds.

Explanation:
Final answer:
The question involves creating a program in Computers and Technology to calculate the distance of free-fall in meters and feet over 10 seconds using physics formulas and programming methods for calculations and conversions.
Explanation:
The student's question involves writing a program that calculates the distance an object falls in meters over 10 seconds, as well as converting that distance to feet. This problem applies the physics concept of free-fall, using the equation of motion h = (1/2) * g * t^2, where h is the height, g is the acceleration due to gravity (9.81 m/s2), and t is the time in seconds. The student should also write a method to convert the distance from meters to feet (1 meter = 3.28084 feet).
The main method should include a loop that calls these methods to generate a table of distances fallen and the corresponding times. To convert meters to feet, the following formula can be used:
feet = meters * 3.28084
