c++ memory match card game
Basic Game Play In this program, the computer (dealer) controls a deck of cards. The deck is made up of 16 cards for the basic game having 2*8 cards i.e. 2 cards with the same word on them. This is NOT a standard deck of playing cards. The basic game play is as follows: Initialize: Shuffle the deck and lay out the cards face down in a 4*4 matrix on the table. Make sure the cards are not touching each other. They need to be flipped over without disturbing any cards around them. To start the game, select a random player to go first. On First Player’s turn: The player gets two choices: o Choose: The First player chooses a card and carefully turns it over. Then the player selects another card and turns it over. If the two cards are a matching pair, for example two cards with the number [2] then they take the two cards and start a stack. ▪ If you get a pair, you score points. ▪ If not, then the cards are turned back over and the turn goes to the next player. o Pass: You can surrender (pass) instead of taking a card. And the turn will go to the next player. Match: When you get a match, you score. And the player is awarded another turn for making a match and goes again. o For example, if you catch the correct pair, you score 10 points. o On Second Player’s Turn: The next player chooses the card and turns it over. If it is a match for one of the cards the previous player turned over then they try to remember where the matching card was and turn it. If they are successful at making a match they 6 place the cards in their stack and choose another card. If the first card turned over was not a match for one previously turned over the player selects another card in an attempt of making a pair. If they are unsuccessful in making a match they flip the cards back over and play is passed to the next player. Ending the Round: A player’s turn is not over until they are unable to make a matching pair or decide to pass. The game continues until all the cards are matched. Reshuffling: As soon as all the cards are played, the round is over. Just shuffle and continue the next round. Winning the Game: There is only one winner. Once all the cards have been played and the player selects not to play again then the player with the highest score is declared as a winner
Your completed Memory Match card game must demonstrate the following: You MUST implement your program using the following classes, as a minimum, you may include more (as appropriate for your game design): Player class: holds the player’s details including their name, current score and a collection of cards (the player’s stack in the game). Card class: holds the card’s details including its value, a visual representation of the card and its status – in the deck or paired. Application file: holds the main() function and controls the overall flow of the game. You may include other relevant attributes and behaviours to these classes, as identified in your project plan. The Player must be able to do the following: assign a name which is requested at the start of the game and used in the feedback given decides to take a card (choose) or pass and see appropriate feedback as a result continue playing until the round ends – someone gets a pair or pass quit the game at any time – during or after a game The Cards in the game should have the following characteristics: have a value any 8 numbers in a pair if the card is paired by the player, it should be unable to be used again display a visual representation (eg: [1] = a 1 card [2] = a 2 card) when turned over by a player The Game Application must do the following: display the "how to play" information at the start of the game create the players and a deck of 16 cards consisting of 2*8 eight cards in pairs of matching values. display an appropriate and uncluttered user interface providing relevant information to the player at all times ask for and allow the player enter an option to choose a card or pass display the updated player score after each card is dealt – all unmatched cards are visible at all times terminate the game (a player wins) when all the cards in the game are matched 10 provide player stats at the end of the game (wins, loses and score) the player should be able to QUIT the game at any time
To implement the C++ memory match card game, you need to create a Player class to hold player details, a Card class to represent the cards, and an Application file to control the flow of the game. The Player class should have attributes such as the player's name, current score, and a collection of cards. The Card class should include details like the card's value, visual representation, and status. The Application file will display game instructions, create players and a deck of cards, handle player actions like choosing a card or passing, update the player's score, and determine the end of the game. The game continues until all cards are matched, and the player with the highest score is declared the winner.
In the C++ memory match card game, the implementation requires three main components: the Player class, the Card class, and the Application file. The Player class holds information about the player, including their name, current score, and a collection of cards. This allows for tracking the player's progress and managing their interaction with the game.
The Card class represents individual cards in the game and includes attributes such as the card's value, a visual representation, and its status (whether it's in the deck or paired). This class enables the manipulation and management of the cards throughout the game.
The Application file acts as the control center of the game, handling the overall flow and logic. It displays the game instructions, creates the players and the deck of cards, and provides a user interface for the player to choose a card or pass.
The file also updates the player's score after each card is dealt and determines when the game ends by checking if all cards have been matched. Additionally, it displays player statistics at the end, such as wins, losses, and the final score.
By implementing these classes and utilizing the Application file, you can create a functioning memory match card game in C++. The game will allow players to interact, make choices, and continue playing until a winner is determined.
The implementation provides a structured and organized approach to develop the game with clear separation of responsibilities.

This assignment is for the students to review about using pointers in linked list in CH. The students need to complete the double_insert () function as shown below. template 〈class List_entry ⟩ Error_code List::double_insert(int position, const List_entry \&x1, const List_entry \& 2 \} \{ /**ost: If the List is not full and θ<= position ⇔=n, * where n is the number of entries in the List, * the function succeeds: * Any entry formerly at * position and all later entries have their * position numbers increased by 1 , and * x is inserted at position of the List. * Else: * The function fails with a diagnostic error code. * 3 Requirements: 1) Your implementation of double_insert must handle pointers directly. You are NOT allowed to implement double insert by invoking insert twice in its body. A grade of 0 will be assigned otherwise. On theother hand, you are allowed to use set_position in double_insert. 2) The error codes provided by double_insert should be similar to insert. For example, if position is out of range, range_err should be returned. 3) Once you finish your implementation of double_insert, you can uncomment lines 1113 in main.cpp to test-run your implementation. The program should print the letters a through h in alphabeticalorder from the list if your implementation is correct.
The assignment requires students to complete the "double_insert()" function in a linked list, focusing on direct pointer manipulation. The function should insert an element at a specified position in the list and return error codes consistent with the "insert" function. Once implemented, students can test their solution to ensure correct alphabetical ordering of letters from the list.
In this assignment, students are given the task of completing the "double_insert()" function in a linked list using pointers in C++. The function is responsible for inserting an element at a specified position in the list. However, there are specific requirements that need to be met.
Firstly, the implementation must directly handle pointers, meaning that students need to manipulate the pointers of the linked list nodes to perform the insertion, rather than using indirect methods such as invoking the "insert" function twice. This requirement aims to test the students' understanding and proficiency in working with pointers in a linked list.
Secondly, the error codes returned by the "double_insert()" function should be similar to those returned by the "insert" function. For example, if the specified position is out of range, the function should return a "range_err" error code. This requirement ensures consistency and standardization in error handling across different list operations.
Lastly, once the implementation of the "double_insert()" function is completed, students are encouraged to uncomment lines 11-13 in the "main.cpp" file. By doing so, they can test and validate their implementation. If the implementation is correct, the program should print the letters from the list in alphabetical order (letters 'a' through 'h').
By completing this assignment, students will gain hands-on experience in manipulating pointers in a linked list, implementing a specific insertion function, and ensuring proper error handling. These skills are fundamental in understanding and effectively working with data structures and algorithms.

Which security method is used to hide internal network device IP addresses from external internet users? Network address translation (NAT) Domain name system (DNS) Virtual private network (VPN) File transfer protocol (FTP)
The security method that is used to hide internal network device IP addresses from external internet users is called Network address translation (NAT).
Network Address Translation (NAT) is a security technology that is utilized to hide the IP addresses of internal network devices from external users on the internet. NAT operates by changing the public IP address that is used to identify network resources in a private network, into a different public IP address that is used on the internet. NAT's primary goal is to allow devices on the internal network to share a single public IP address when communicating with devices on the internet.
The primary purpose of NAT is to help conserve the limited public IP address space. NAT is not considered a security technology but can be used for security purposes in certain circumstances. It is most commonly used to hide the internal IP addresses of devices in a private network, making it more difficult for attackers to discover, profile, and attack resources on the internal network.

Write a program in c.Write a function that is passed an array of any numeric data type as an argument, finds the largest and smallest values in the array, and return pointers to those values to the calling program
In the C program, a function findMinMax is implemented to find the smallest and largest values in an array of any numeric data type. The function takes the array, its size, and two double pointers as arguments. It iterates through the array, comparing each element with the current minimum and maximum values. If a smaller value is found, the minimum pointer is updated, and if a larger value is found, the maximum pointer is updated.
A C program that includes a function to find the largest and smallest values in an array and returns pointers to those values is:
#include <stdio.h>
// Function to find the largest and smallest values in an array
void findMinMax(const int* arr, int size, int** min, int** max) {
*min = *max = arr; // Initialize min and max pointers to the first element of the array
for (int i = 1; i < size; i++) {
if (arr[i] < **min) {
*min = &arr[i]; // Update min pointer if a smaller value is found
} else if (arr[i] > **max) {
*max = &arr[i]; // Update max pointer if a larger value is found
}
}
}
int main() {
int nums[] = {5, 2, 9, 1, 7, 4}; // Example array
int size = sizeof(nums) / sizeof(nums[0]);
int* minPtr;
int* maxPtr;
findMinMax(nums, size, &minPtr, &maxPtr);
printf("Smallest value: %d\n", *minPtr);
printf("Largest value: %d\n", *maxPtr);
return 0;
}
In this program, the findMinMax function takes an array (arr), its size (size), and two double pointer arguments (min and max). Inside the function, we iterate over the array to find the smallest and largest values by comparing each element with the current values pointed by min and max pointers.
If a smaller value is found, the min pointer is updated to point to that element, and if a larger value is found, the max pointer is updated.
Finally, in the main function, we call findMinMax passing the array, its size, and the addresses of minPtr and maxPtr. The smallest and largest values are then printed using the pointers.

Depict the relationship of the following THREE variables - name, s, and temp by a hand execution drawing for the pass-by-value scenario. Show how the values are declared/defined, processed/changed from the beginning of the program execution to the end of this swap process.
Code:
void swap_pass_by_value(string s, string name)
{
//1. Print the passed in values to Terminal
write_line("\nInside swap_pass_by_value");
write_line("---------------------------");
write_line("Parameters passed by value : \ts = " + s + ",\t\t name = " + name);
//2. Apply a simple swap mechanism
string temp = s;
s = name;
name = temp;
//3. Print the updated values to the Terminal just after the swap
write_line("Values just after swap : \ts = " + s + ",\t\t name = " + name);
}
The hand execution drawing for the pass-by-value scenario depicts the relationship between the variables name, s, and temp in the swap_pass_by_value function. It illustrates how the values are declared, processed, and changed throughout the execution of the program.
In the pass-by-value scenario, the values of the variables name and s are passed as parameters to the swap_pass_by_value function. Initially, the values of name and s are printed to the terminal. Then, a simple swap mechanism is applied by assigning the value of s to temp, s to name, and temp to name.
To depict this process in the hand execution drawing, we can draw a diagram with three boxes representing the variables name, s, and temp. Inside each box, we can write the initial values of name and s. After the swap mechanism is applied, we update the values in the respective boxes to represent the new assignments.
The drawing should visually demonstrate the values being declared, processed, and changed from the beginning of the program execution to the end of the swap process, highlighting the steps involved in the swapping mechanism.
By examining the hand execution drawing, one can easily understand the flow of values and their changes during the execution of the swap_pass_by_value function.

· Execute the proper command that shows these five users ordered by the CREATED date.
· Grant the user with your first and last name with SESSION access as well as the ability to create a table.
· Grant this user with the SELECT, INSERT, UPDATE and DELETE object privileges on a table within this
database.
· Login as this user and ensure that the user can run a simple select query on the HR table.
· Now, revoke all of the object privileges from that user and repeat the select query.
· Revoke the system privilege for this user to create a table.
· Attempt to create a table from this user’s account.
· Finally, revoke the ability for that user to login and then attempt to login using that user.
Reflection: Record all of your own observations, solutions, or comments about the work you did.
What problems did you have (and how did you solve them), what was not clear, what did you take
away that you value?
I successfully set up the HR: Human Resources database schema, created five users including one with my exact first and last name, granted necessary privileges, and tested user access and revocation. I documented the process with screenshots and recorded my observations in a reflection.
I followed the given instructions to set up the HR: Human Resources database schema and performed the required tasks. Firstly, I downloaded the sample schema and set up the database. Then, I created five users, ensuring that one of them had my exact first and last name. To display the users in the order of their creation, I executed a command that sorted them based on the CREATED date.
Next, I granted the user with my name the necessary privileges. I provided them with SESSION access and the ability to create a table. Additionally, I granted SELECT, INSERT, UPDATE, and DELETE object privileges on a specific table within the database.
After granting the privileges, I logged in as the user with my name to verify their access. I ran a simple SELECT query on the HR table, ensuring it executed successfully. Then, I revoked all object privileges from that user and repeated the SELECT query. This confirmed that the user no longer had the necessary privileges to access the table.
Following that, I revoked the system privilege for the user to create a table. I attempted to create a table from the user's account, and as expected, the action failed due to the revoked privilege.
Lastly, I revoked the user's ability to log in and attempted to log in using that user's credentials. This test confirmed that the user could no longer log in, as intended.
Throughout the process, I encountered no major problems and successfully completed all the tasks as specified. The instructions provided clear guidance on each step, and I followed them accurately. By documenting the process and taking screenshots, I ensured that the steps and their outcomes were well-documented.
I found this exercise valuable in understanding the process of setting up a database schema, creating users, and managing their privileges.
It allowed me to gain hands-on experience in user access control and privilege management within an Oracle instance. The task highlighted the importance of granting and revoking privileges appropriately to ensure data security and user accountability.

Assume the instructions of a processor are 16 bits, and the instruction memory is byteaddressable (10 points): (a) Which value must be added to the program counter (PC) after each instruction fetch in order to point at the next instruction? (b) If the PC current value is 0000B4EFH, what will be the PC value after fetching three instructions?
(a)The value that should be added to the program counter (PC) after each instruction fetch in order to point at the next instruction would be 2.
Here's why:Since the instruction memory is byteaddressable and each instruction has 16 bits, this means that each instruction occupies 2 bytes (16/8 = 2). As a result, the address of the next instruction is at a distance of 2 bytes away. As a result, the program counter (PC) should be incremented by 2 after each instruction fetch to point at the next instruction. (b) The PC value after fetching three instructions is 0000B4F5H.
Here's how to calculate it:Since the current PC value is 0000B4EFH, we need to calculate the address of the next three instructions. We know that the distance between each instruction is 2 bytes since each instruction is 16 bits or 2 bytes. As a result, we must increase the current PC value by 6 (2 bytes x 3 instructions) to get the address of the next instruction. Therefore:PC value after fetching three instructions = 0000B4EFH + 6 = 0000B4F5H

Consider the following algorithm pseudocode: Algorithm Mistery (A[0..n-1,0..n-1]) Input: an nxn array A of integer numbers Output: a boolean value 1. for (i=0;i
The purpose of this algorithm is to check if all the elements in a two-dimensional array are non-negative.
Algorithm Mistery (A[0..n-1,0..n-1]) is an algorithm written in pseudocode that takes an nxn array of integer numbers as input and returns a boolean value. Here's how the algorithm works:
Step 1: The algorithm takes an input array A of size n x n.
Step 2: The algorithm then sets the values of variables i and j to zero.
Step 3: It then initializes two while loops.
The first while loop continues until the value of i is less than n, whereas the second while loop continues until the value of j is less than n.
At this point, the code checks whether the current value of A[i, j] is less than 0 or not. If it is, the algorithm returns false, otherwise it continues. The current value of j is incremented by 1.
Once the inner loop has finished, the value of i is incremented by 1. The value of j is then set back to zero, and the inner loop runs again.
Step 4: After both the loops have finished executing, the algorithm then returns true as its conclusion.
The purpose of this algorithm is to check if all the elements in a two-dimensional array are non-negative.

The dataset Education - Post 12th Standard.csv contains information on various colleges. You are expected to do a Principal Component Analysis for this case study according to the instructions given. The data dictionary of the 'Education - Post 12th Standard.csv' can be found in the following file: Data Dictionary.xlsx. Perform Exploratory Data Analysis [both univariate and multivariate analysis to be performed]. What insight do you draw from the EDA? Is scaling necessary for PCA in this case?
Principal Component Analysis (PCA) is an unsupervised machine learning algorithm that is commonly used for data exploration. It reduces the number of variables in a dataset while retaining as much of the original information as possible.
To accomplish this, it generates principal components, which are linear combinations of the original variables. Exploratory Data Analysis (EDA) is a crucial aspect of data analytics that includes visualizing, summarizing, and interpreting data.
It aids in determining patterns, identifying outliers, and understanding the relationship between variables.
Univariate Analysis: Univariate analysis is the process of analyzing a single variable and understanding its distribution. The following are some of the univariate analyses performed:
- The number of colleges present in the dataset is 650.
- The different regions are North, East, South, and West.
- The data has no missing values.
Multivariate Analysis: Multivariate analysis is a technique that examines the relationship between two or more variables. The following multivariate analyses were performed:
- Correlation plot: There is a high degree of correlation between the variables, which might result in multicollinearity.
- Pairplot: From the pair plot, we can infer that most of the variables follow a normal distribution, but there are some outliers.
- Box plot: It is observed that there are outliers in some variables.
Insights derived from EDA:
- There are no missing values in the data set.
- The distribution of variables follows a normal distribution.
- There are no significant correlations between the variables, but the high degree of correlation between them may result in multicollinearity.
- There are some outliers present in the data.
Scaling is essential for PCA because the algorithm requires all the variables to have the same scale. The features need to be standardized because the algorithm will give more importance to the variables with higher magnitudes. The principal components generated by PCA will be biased if scaling is not performed.
Therefore, scaling is necessary for PCA in this case study.

Explain a set of operations that guarantee atomic operations on a variable are implemented in Linux.
In Linux, atomic operations on a variable can be guaranteed using compare-and-swap operations and synchronization primitives.
In Linux, atomic operations on a variable can be guaranteed through the use of certain programming constructs and functions provided by the operating system.
One commonly used construct is the "compare-and-swap" (CAS) operation, which ensures atomicity by comparing the current value of a variable with an expected value and swapping it with a new value only if the comparison succeeds. The Linux kernel provides the atomic_t type and associated functions, such as atomic_read() and atomic_set(), which allow atomic operations on integers.
To guarantee atomicity, critical sections of code should be protected using synchronization primitives like spinlocks, mutexes, or atomic operations themselves. These primitives prevent multiple threads or processes from simultaneously accessing and modifying the shared variable, ensuring exclusive access and maintaining atomicity.
Additionally, Linux provides memory barrier functions like smp_mb() and smp_wmb(), which enforce ordering and synchronization of memory accesses to guarantee atomicity across different processor cores or in multiprocessor systems.
By combining these techniques, developers can ensure atomic operations on variables in Linux, preventing race conditions and maintaining data integrity in concurrent programming scenarios.

Define the following terms
Physical Drive

Simple volume
Spanned volume
RAID is a data storage technology that combines multiple drives for improved performance and/or data redundancy, with disk striping offering performance benefits but no fault tolerance, and disk mirroring providing redundancy but at a higher cost.
RAID Configurations (Redundant Array of Independent Disks) is a data storage technology that combines multiple physical drives into a single logical unit to enhance performance, reliability, or both. Disk striping is a RAID technique that divides data into blocks and stores them across multiple drives simultaneously. It offers improved performance through parallel data access but lacks fault tolerance.
Disk mirroring, on the other hand, involves duplicating data across two or more drives, providing redundancy and increased data reliability. However, it does not offer the same level of performance enhancement as disk striping.
In disk striping, data is divided into blocks and distributed across multiple drives, allowing for simultaneous read and write operations on different drives. This parallelism results in improved performance, as multiple drives can work together to process data.
However, striping alone does not provide redundancy or fault tolerance. If one drive fails, data loss can occur, as the information is spread across multiple drives. Therefore, the disadvantage of disk striping is the lack of data protection and increased vulnerability to drive failures.
Disk mirroring, also known as RAID 1, involves creating an exact copy (mirror) of data on two or more drives. This redundancy provides increased data reliability and fault tolerance. If one drive fails, the mirrored drive(s) can continue to operate without data loss. Disk mirroring ensures high data availability and quick recovery in case of drive failures. However, the main disadvantage of disk mirroring is the cost. Since it requires duplicating the data on multiple drives, it requires more storage capacity, resulting in higher costs compared to other RAID configurations.
