Question

Lets get ready for the basketball tournament! Assume the class Bracket has the following interface:

class Bracket
{
 public:
 Bracket(string location);
 string getdata() const;
 private:
 string location;
};

The function getdata should return the value of the attribute. Write the member functions for this class. ALSO - rewrite the interface so that the getdata function is virtual.

Create a class Team which is derived from the base class Bracket. Include a constructor that accepts the location (Bracket) and the team name which is a string attribute for the class. Also include a function getdata which returns the team name.

1. Create a class Player which is derived from the base class Team. Include a constructor that accepts the location (Bracket), team name (Team) and the player name which is a string attribute for the class. Also include a function getdata which returns the player name.
2. a. Write a main program that creates a vector v of Bracket* (pointer) objects by reading the data in from a file. The file (named tournament.txt) has the following format. Each line in the file has four string values (all without spaces)

   string1 string2 string3 string4
   

   • String1 indicates the type of the record - Bracket, Team, Player.
   • String2 is the Bracket name.
   • String3 is the Team name (if the record type is Bracket, the value is na).
   • String4 is the Player name (if the record type is Bracket or Team, the value is na).

   b. Process the vector v by applying the getdata function to each value object pointed to by elements of the vectori and outputing the result - one value per line.
