Answer:
In pass-by-value, the function receives a copy of the argument as a parameter. This means that any changes made to the parameter inside the function have no effect on the argument outside the function.
On the other hand, in pass-by-reference, the function receives a reference to the memory location of the argument. This means that any changes made to the parameter inside the function are reflected in the argument outside the function.
Here is an example in C++ to illustrate the difference:
#include <iostream>
void increment(int x)
{
x++;
}
void increment(int* x)
{
(*x)++;
}
int main()
{
int y = 5;
increment(y); // pass-by-value
std::cout << y << std::endl; // prints 5
increment(&y); // pass-by-reference
std::cout << y << std::endl; // prints 6
retuIn the first call to increment, the value of y is passed to the function as a parameter. Since the function receives a copy of the value of y, any changes made to the parameter inside the function have no effect on the argument outside the function. Therefore, the value of y is not changed and remains 5.
In the second call to increment, the memory address of y is passed to the function as a parameter. Since the function receives a reference to the memory location of y, any changes made to the parameter inside the function are reflected in the argument outside the function. Therefore, the value of y is incremented to 6.rn 0;

Answer:
Severe riboflavin deficiency can impair the metabolism of other nutrients, especially other B vitamins, through diminished levels of flavin coenzymes [3]. Anemia and cataracts can develop if riboflavin deficiency is severe and prolonged [1]. The earlier changes associated with riboflavin deficiency are easily reversed.

The vulnerabilities common to the software development process, including buffer overflows, race conditions, input validation attacks, authentication attacks, authorization attacks, and cryptographic attacks, and how we might mitigate these by following secure coding guidelines. Besides protecting O S software on hosts, there is a need to protect applications that run on these devices. Aspects of application security includes all except:____.
A. Application development security.
B. Secure coding techniques.
C. Code testing.
D. Requirement Assessment.
Answer:
Aspects of application security includes all except:____.
D. Requirement Assessment.
Explanation:
The requirement assessment is carried out during the initial development stage to meet the user's requirements. This assessment does not necessarily deal with application security. However, the other three aspects are security-related. They focus on the areas where application security is mostly required to reduce errors and technical weaknesses of a software, including authentication, privacy, access control, data segregation, and error handling.

C++ StructuresC++ StringsIn this program, a structure(student) is created which contains name, roll and marks as its data member. Then, a structure variable(s) is created. Then, data (name, roll and marks) is taken from user and stored in data members of structure variable s. Finally, the data entered by user is displayed.This structure has three members: name (string), roll (integer) and marks (float).
Then, a structure variable s is created to store information and display it on the screen.

outline four advantages of digital
cameras over analogue cameras
Answer:
Explanation:
A digital camera refers to a camera whereby the photographs are being captured in digital memory. An analogue camera refers to the traditional camera that typically sends video over cable.
The advantages of digital cameras over analogue cameras include:
1. Massive Storage Space:
There is a large storage space for photos and thus helps to prevent limitations to film. There are memory cards that can store several images.
2. Multiple functions:
The digital camera performs several functions like face detection, night and motion detection This makes capturing of images more fun and brings about better images.
3. Video Camera:
Digital cameras can also capture moving pictures while analog camera typically captures images that are still. Digital camera is vital as it can be used for live streaming.
4. Smaller and Lighter:
Digital cameras are usually smaller and lighter which makes them more portable and easy to carry about.

What is the output of the following code?
int num=25;
if (num > 5)
System.out.print(num + " ");
num += 10;
}
if (num > 30){
System.out.print(num + " ");
num += 5;
}
if (num > 45 ) {
System.out.print(num);
}
Answer:
25 35
Explanation:
First if checks if num is greater than 25, it is so it prints 25 with a space after and adds 10 to num (num is now 35)
Then it checks if num is greater than 30, it is, so it prints 35 with a space after and adds 5 to num (num is now 40)
Lastly, it checks if num is greater than 45, it is not, so the program terminates with output: "25 35 " (note the space at the end)

You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types.
What you need to do?
1. Writing detailed comments and docstrings
2. Organizing and structuring code for readability
3. URL = :///
Steps for Completion
Task
Create two lists of strings - one list for Protocol called valid_protocols, and one list for storing File extension called valid_ftleinfo . For this take the protocol list should be restricted to http , https and ftp. The file extension list should be hrl. and docx CSV.
Split an input named url, and then use the first element to see whether the protocol of the URL is in valid_protocols. Similarly, check whether the URL contains a valid file_info.
Task
Write the conditions to return a Boolean value of True if the URL is valid, and False if either the Protocol or the File extension is not valid.

5.27 LAB*: Program: Soccer team roster (Vectors)
This program will store roster and rating information for a soccer team. Coaches rate players during tryouts to ensure a balanced team.
(1) Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99) and the player's rating (1 - 9). Store the jersey numbers in one int vector and the ratings in another int vector. Output these vectors (i.e., output the roster). (3 pts)
Ex:
Enter player 1's jersey number:
84
Enter player 1's rating:
7
Enter player 2's jersey number:
23
Enter player 2's rating:
4
Enter player 3's jersey number:
4
Enter player 3's rating:
5
Enter player 4's jersey number:
30
Enter player 4's rating:
2
Enter player 5's jersey number:
66
Enter player 5's rating:
9
ROSTER
Player 1 -- Jersey number: 84, Rating: 7
Player 2 -- Jersey number: 23, Rating: 4
...
(2) Implement a menu of options for a user to modify the roster. Each option is represented by a single character. The program initially outputs the menu, and outputs the menu after a user chooses an option. The program ends when the user chooses the option to Quit. For this step, the other options do nothing. (2 pts)
Ex:
MENU
a - Add player
d - Remove player
u - Update player rating
r - Output players above a rating
o - Output roster
q - Quit
Choose an option:
(3) Implement the "Output roster" menu option. (1 pt)
Ex:
ROSTER
Player 1 -- Jersey number: 84, Rating: 7
Player 2 -- Jersey number: 23, Rating: 4
...
(4) Implement the "Add player" menu option. Prompt the user for a new player's jersey number and rating. Append the values to the two vectors. (1 pt)
Ex:
Enter a new player's jersey number:
49
Enter the player's rating:
8
(5) Implement the "Delete player" menu option. Prompt the user for a player's jersey number. Remove the player from the roster (delete the jersey number and rating). (2 pts)
Ex:
Enter a jersey number:
4
(6) Implement the "Update player rating" menu option. Prompt the user for a player's jersey number. Prompt again for a new rating for the player, and then change that player's rating. (1 pt)
Ex:
Enter a jersey number:
23
Enter a new rating for player:
6
(7) Implement the "Output players above a rating" menu option. Prompt the user for a rating. Print the jersey number and rating for all players with ratings above the entered value. (2 pts)
Ex:
Enter a rating:
5
