For this assignment, implement and use the methods for a class called Seller that represents information about a salesperson.
The Seller class
Use the following class definition:
class Seller { public: Seller(); Seller( const char [], const char[], const char [], double ); void print(); void setFirstName( const char [] ); void setLastName( const char [] ); void setID( const char [] ); void setSalesTotal( double ); double getSalesTotal(); private: char firstName[20]; char lastName[30]; char ID[7]; double salesTotal; };
Data Members
The data members for the class are:
firstName holds the Seller's first name
lastName holds the Seller's last name
ID holds the Seller's id number
salesTotal holds the Seller's sales total
Constructors
This class has two constructors. The default constructor (the one that takes no arguments) should initialize the first and last names to "None", the seller ID to "ZZZ999", and the sales total 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 Seller's first name, a character array with a Seller's last name, a character array with a Seller's id number, and a double that holds the Seller's sales total. The data members should be initialized by calling the various set methods.
Methods
void print()
This method displays the Seller information. It takes no arguments and returns nothing.
The information should be displayed as follows:
Giant, Andre BIG357 678.53
void setFirstName( const char [] )
This method changes a Seller's first name. It takes one argument: an array of characters that represents the Seller's first name. It returns nothing.
If the length of the passed in argument is greater than 0, it should be used to initialize the firstName data member. Otherwise, the firstName data member should be set to "None".
void setLastName( const char [] )
This method changes a Seller's last name. It takes one argument: an array of characters that represents the Seller's last name. It returns nothing.
If the length of the passed in argument is greater than 0, it should be used to initialize the lastName data member. Otherwise, the lastName data member should be set to "None".
void setID( const char [] )
This method changes a Seller's id number. It takes one argument: an array of characters that represents the Seller's id number. It returns nothing.
If the length of the passed in argument is greater than 0 and less than 7, it should be used to initialize the ID data member. Otherwise, the ID data member should be set to "ZZZ999".
void setSalesTotal( double )
This method changes a Seller's sales total. It takes one argument: a double that represents the Seller's sales total. It returns nothing.
If the passed in argument is greater than or equal to 0, it should be used to initialize the salesTotal data member. Otherwise, the salesTotal data member should be set to 0.
double getSalesTotal()
This method returns a Seller's sales total data member. It takes no arguments.
main()
In main(), create 5 Seller objects. They should contain the values:
The first Seller should have your name, an id of "CSI240", and a sales total of 1234.56. Note: if you're pair programming, set the first name to the first name of both you and your partner: "Jane/John" and the last name to the last name of both you and your partner: "Doe/Doe".
The second Seller should be created using the default constructor (the one that doesn't take any arguments)
The third Seller should have the first name of an empty string (""), a last name of "Robinson", an id of "TOOBIG999", and a sales total of -876.34.
The fourth Seller should have the name "Tarik Cohen", an id of "RUN29", and a sales total of 13579.11
The fifth Seller should have the name "Kyle Long", an id of "TACK75", and a sales total of 24680.24
The rest of main() will include using the various methods on each of the 5 Seller objects. Display a label similar to "The first Seller" before anything is outputted for each of the objects.
For the first Seller, display the Seller information.
For the second Seller, display the Seller information, set the Seller name to "Mitchell Trubisky", set the id number to "QB10", set the sales total to 246.80, and then display the Seller information once again.
For the third Seller, display the Seller's information, set the Seller's first name to "Allen", set the id number to "WIDE12", set the sales total to 9900000.99, and then display the Seller information once again.
For the fourth Seller, display only the Seller's sales total.
For the fifth Seller, display the Seller's information, set the first name to an empty string (""), set the last name to an empty string, set the id number to an empty string, set the sales total to -52.96, and then display the Seller information once again.
Programming Notes
Each method must have a documentation box like a function.
Hand in a copy of the source code using Blackboard.
Output
Note: The information for the first Seller object will have your name.
