Overview

For this assignment, implement and use the methods for a class called Player that represents a player in the National Hockey League.

Player class

Use the following class definition:

class Player
{
public:
  Player();
  Player( const char [], int, int, int );
    
  void printPlayer();

  void setName( const char [] );
  void setNumber( int );
  
  void changeGoals( int );
  void changeAssists( int );

  int getNumber();
  int getGoals();
  int getAssists();

private:
  char name[50];
  int number;
  int goals;
  int assists;
};

Data Members

The data members for the class are:

• name this holds the player's name

• number this holds the player's number

• goals this holds the number of goals that the player has scored

• assists this holds the number of assists that the player has earned

Constructors

This class has two constructors. The default constructor (the one that takes no arguments) should initialize the name to the null string (this can be done by assigning '\0' to the 0th spot of the character array or by using strcpy to copy an empty string ("") into the character array) and the integer data members to 0.

The other constructor for the class should initialize the data members using the passed in arguments. It takes 4 arguments: a character array with a player name, and integer that holds the player's number, an integer that holds the number of goals that the player has scored, and an integer that holds the number of assists the player has earned. The numeric values can be initialized with simple assignment statements or by calling the set/change methods that are described below. However, if the change methods are going to be used, don't forget to set the individual data members to 0 before calling the appropriate change method. Use the setName method or a simple call to strcpy function to initialize the name.

Methods

void printPlayer()

This method displays the player information and the number of points. It takes no arguments and returns nothing. The number of points is calculated as follows:

Points = number of goals + number of assists

The information should be displayed as follows:

Steven Stamkos     #91
Goals: 1       Assists: 1        Points: 2

void setName( const char playerName[] )

This method sets/changes a player's name. It takes one argument: an array of constant characters that represents the player's name. It returns nothing.

Use the strcpy function to assign the passed in argument to the name data member. No error checking is required.

void setNumber( int newNumber )

This method sets/changes a player's number. It takes one argument: an integer that represents the player's number. It returns nothing.

Use a simple assignment statement to assign the passed in argument to the number data member. No error checking is required.

void changeGoals( int goalsScored )

This method changes a player's number of goals. It takes one argument: an integer that represents the number of goals that have recently been scored by the player. It returns nothing.

If the passed in number of goals that have recently been scored is less than 0, display an error message and do not make any changes to the goals data member. If the passed in number of goals that have recently been scored is greater than or equal to 0, increment the goals data member by the passed in number of goals that have been scored.

void changeAssists( int assistsEarned )

This method changes a player's number of assists. It takes one argument: an integer that represents the number of assists that have recently been earned by the player. It returns nothing.

If the passed in number of assists that have recently been earned is less than 0, display an error message and do not make any changes to the assists data member. If the passed in number of assists that have recently been earned is greater than or equal to 0, increment the assists data member by the passed in number of assists that have been earned.

int getNumber()

This method returns a player's number. It takes no arguments.

int getGoals()

This method returns a player's number of goals scored. It takes no arguments.

int getAssists()

This method returns a player's number of assists earned. It takes no arguments.

main()

In main(), create 6 Player objects. They should contain the values:

• The first player should have your name, the number 66, 5 goals scored, and 3 assists. Note: if you're pair programming, set the name to both you and your partner: "Jane Doe/John Doe".

• The second player should be created using the default constructor (the one that doesn't take any arguments)

• The third player should have the name "Jonathan Toews", the number 19, 35 goals scored, and 46 assists earned

• The fourth player should have the name "Patrick Kane", the number 88, 44 goals scored, and 66 assists earned

• The fifth player should have the name "Alex DeBrincat", the number 12, 41 goals scored, and 35 assists earned

• The sixth player should have the name "Dylan Strome", the number 17, 20 goals scored, and 37 assists earned

The rest of main() will include using the various methods on each of the 6 Player objects. Display a label similar to "The first Player object" before anything is outputted for each of the objects.

For the first player, display the player information.

For the second player, display the player information, set the player name to "Duncan Keith", set the number to 2, change the number of goals scored to 6, and change the number of assists to 34, and then display the player information once again.

For the third player, display the player's information, using the changeGoals method, try to change the player's number of goals by -8, using the changeAssists method, try to change the player's number of assists by -2, and then display the player information once again.

For the fourth player, display the player's information, using changeAssists, increase the number of assists by 4, and then display the player information once again.

For the fifth player, display only the player's number and the number of goals scored, and then display all the player information.

For the sixth player, display only the player's number and the number of assists earned, and then display all the player information.

Programming Notes

1. Each method must have a documentation box like a function.

2. Hand in a copy of your source code using Blackboard.
