Question
Players Class:
Instance variables: First name of player, Last name of player, Batting average represented by a decimal number from 0 to 1.
Methods:
Default constructor
Constructor that accepts singles, doubles, triples, homeruns and atBats and then calls the calculateAverage
Getters, setters and toString- which displays the player’s name and batting average in a single line:
John Smith .462
Note: Batting average should be displayed with three decimal places.
calculateAverage- This method will accept the number of singles, doubles, triples and homeruns, as well as the number of atBats and then changes the result to set the player’s batting average.
setAverage- This method receives a player’s average already calculated and sets the value.
Team Class:
Instance variables: an array of Players, team name
Methods:
Team batting average- this method will collect the batting average of each player and return the team average.
Getters and setters
outputTeam- this method should output the team name, team average and then in a loop, call the toString of the Player Class
Red Sox Team Average: .486
Player Batting Average
John Smith .528
Adam Sandler .479
….
Driver Class:
Create four instances of the Team Class.
Read in a file of player names and number of singles, doubles, triples, homeruns and atBats, as well as the team name. The file should contain at least 40 players, representing four different teams. The team order of the players should be scrambled. Therefore, each record read should create a new instance of the player class, determine batting average, store that average into the player instance variable, determine which team the player is on, and then add the player to the array of the correct team.

Explanation / Answer
here is your program :==========
#include<iostream>
#include<fstream>
using namespace std;

}

}

double avr = (sing+2*doub+3*trip+home)/atBats;
setAvarage(avr);
}
void setAvarage(double avr){
// if(avr < 1 && avr > 0){

// }
}

}
