Extra Credit: $00$P $2$: Derived Classes $\backslash$& Polymorphism

Objectives:

After performing this lab, the students should be able to

$-$ Implement derived class

$-$ Understand and use polymorphism in your code

Activities

Part A: Inheritance

You have been hired by the Chaffey football team to create a roster of players for display during sporting events regardless of sport $($football$,$ soccer, etc$).$

Create a Base class called basePlayer with the following:

$1)$ Private Member variables:

a$.$ int PlayerAge

b$.$ Strings LastName and FirstName

$2)$ Public Member functions:

a$.$ SetName which takes the players first and last name

b$.$ SetPlayerAge which takes an int player age

c$.$ Print which prints

Create a derived class called SportsPlayer with the following:

$1)$ Private variables:

a$.$ String pNum

$2)$ Public

a$.$ SetPlayerNumber which takes a string player number similar to $"\backslash$#$42"$

Create a main in which you are able to populate the following players and print:

John Doe, $20$ years of Age, Player number $42$

Jane Doe, $21$ years of Age, Player number $22$

Part B: Use Polymorphism

Write a new virtual print function for the base class below. $```$

#include

#include

#include

using namespace std;

class BaseUser $\{$

public:

void SetLastName$($string lName$)\{$

lastName $=$ lName;

$\}$;

$/*$ Create a new virtual function

$/*$ here for the base class$*/$

protected:

string lastName;

$\}$;

class derivedUser : public BaseUser $\{$

public:

void SetFirstName$($string fName$)\{$

firstName $=$ fName;

$\}$;

void PrintItem$()\{$

cout $$ "Player First and last name: $"$;

cout $$ firstName lastName $$ endl;

$\}$;

private:

string firstName;

$\}$;

int main$()$

$\{$

cout welcome player $=======$

$"$;

BaseUser$*$ BaseUserPtr $=$ nullptr;

derivedUser$*$ derivedUserPtr $=$ nullptr;

vector userList;

BaseUserPtr $=$ new BaseUser$()$;

BaseUserPtr$->$SetLastName$("$Luigi$")$;

derivedUserPtr $=$ new derivedUser$()$;

derivedUserPtr$->$SetLastName$("$Mario$")$;

derivedUserPtr$->$SetFirstName$("$Super$")$;

userList.push$\_$back$($BaseUserPtr$)$;

userList.push$\_$back$($derivedUserPtr$)$;

for $($int i $=0$; i $$ userList.size$()$; $++$i$)\{$

userList.at$($i$)->$PrintItem$()$;

$\}$

return $0$;

$\}$
