Assignment $3$: Game Scores Management with Singly Linked List $($Without User Input$)$

Develop a C$++$ application to manage the top game scores using a singly linked list,

implementing add and remove functionalities. This includes creating a GameEntry

class, a GENode class for the linked list structure, and a Scores class to manage

the game entries. The singly linked list will have a maximum number of elements

it can hold $($maxEntries data member$).$

$***$

Part $1$: Implementation

### GameEntry Class Implementation

Create a class GameEntry to store game entries.

#### GameEntry.h $($Header File$)$

$-$ Member Variables $($Private$)$:

$-$ std::string name; $//$ Player's name

$-$ int score; $//$ Player's score

$-$ Member Functions $($Public$)$:

$-$ GameEntry$($const std::string& n$="",$ int s$=0)$; $//$ Constructor

$-$ std::string getName$()$ const; $//$ Get player nAssignment $3$: Game Scores Management with Singly Linked List $($Without User Input$)$

Part $1$: Implementation

### GameEntry Class Implementation

Create a class GameEntry to store game entries.

#### GameEntry.h $($Header File$)$

$-$ Member Variables $($Private$)$:

$-$ std::string name; $//$ Player's name

$-$ int score; $//$ Player's score

$-$ Member Functions $($Public$)$:

$-$ GameEntry$($const std::string& n$="",$ int s$=0)$; $//$ Constructor

$-$ std::string getName$()$ const; $//$ Get player name

$-$ int getScore$()$ const; $//$ Get player score

$-$ void setName$($std::string nName$)$; $//$ Set player name

$-$ void setScore$($int nScore$)$; $//$ Set player score

#### GameEntry.cpp $($Implementation File$)$

$-$ Implement the functions declared in GameEntry.h$.$

### GENode Class Implementation

Develop GENode with the following structure to represent a node in the singly linked list.

#### GENode.h $($Header File$)$

$-$ Member Variables $($Private$)$:

$-$ GameEntry elem; $//$ Game entry stored in the node

$-$ GENode$*$ next; $//$ Pointer to the next node

$-$ Member Variables $($Public$)$:

$-$ static int activeNodes; $//$ Static variable to track number of active nodes

$-$ Member Functions $($Private$)$:

$//$ Inside the body of the constructor increment activeNodes by one

$//$when a node is created

$-$ GENode$($const GameEntry& e$,$ GENode$*$ n $=$ nullptr$)$; $//$ Constructor

$-$ Member Functions $($Public$)$:

$//$ Inside the body of the destuctor decrement activeNodes by one

$//$when a node is destroyed

$-$ ~GENode$()$;

### Scores Class Implementation

Construct Scores to manage a list of GameEntry objects using a singly linked list.

#### Scores.h $($Header File$)$

$-$ Member Variables $($Private$)$:

$-$ int maxEntries; $//$ Maximum number of entries

$-$ int numEntries; $//$ Current number of entries

$-$ GENode$*$ head; $//$ Head of the list

$-$ GENode$*$ tail; $//$ Tail of the list

$-$ Member Functions $($Public$)$:

$-$ Scores$($int maxEnt $=10)$; $//$ Constructor

$-$ ~Scores$()$; $//$ Destructor

$-$ void add$($const GameEntry& e$)$; $//$ Add a game entry

$-$ GameEntry remove$($int i$)$ throw$($IndexOutOfBounds$)$; $//$ Remove a game entry

$-$ void printAll$()$; $//$ Print all game entries

$-$ bool empty$()$ const; $//$returns true if the list is empty and false otherwise

$-$ int size$()$ const; $//$returns current number of entries in the list

$-$ int capacity$()$ const; $//$returns max number of entries allowed in the list $($top $5)$

#### Scores.cpp $($Implementation File$)$

$-$ Implement the functions declared in Scores.h$.$

### Exception Handling Implementation

Utilize RuntimeException and IndexOutOfBounds classes for handling exceptions.

### Main Function Implementation

Implement the main function in a separate $.$cpp file $($main$.$cpp$)$ to demonstrate

the functionality of the Scores class.

#### main.cpp

$-$ Include the necessary files

$-$ Initialize the static variable activeNodes with $0$ before main function

example code:

#include $....$

int GENode::activeNodes $=0$;

int main$()\{.....\}$

$-$ Implement the main function

#### Main Function Details

$-$ Create an object of type Scores, with maxEntries $=5.$

$-$ Add $4$ GameEntry items with different scores, minimum score of $5.$

$-$ Print all entries.

$-$ Add $3$ other GameEntry items with scores interspersed among the first $4.$

$-$ Print all entries after additions.

$-$ Remove the first GameEntry item.

$-$ Print all entries after removal.
