Programming Assignment 1
In this project, you will write a program that helps a player select players in Fantasy Premier League game. You have £100 to get 15 players, distributed as follows:
£10 to get 2 goal keepers
£25 to get 5 defenders
£35 to get 5 midfielders
£30 to get 3 forwards
You will develop the following classes:
Player class: It is an abstract base class and has as private data fields
string name;
string team;
string position;
double price;
int ptsPrevSeason;
As regular public methods, the getters and setters of each private data field
An abstract function selectPlayer defined as follows
virtual vector<Player*> selectPlayer(vector<Player*> players)=0;
Goalkeeper class:
This is a derived class of class Player
It overrides selectPlayer method to select the designed players for goalkeeper position
It defines the budget for goalkeepers as static const
Defender class:
This is a derived class of class Player
It overrides selectPlayer method to select the designed players for defender position
It defines the budget for defender as static const
Midfielder class:
This is a derived class of class Player
This is a derived class of class Player
It overrides selectPlayer method to select the designed players for midfielder position
It defines the budget for midfielder as static const
Forward class:
This is a derived class of class Player
It overrides selectPlayer method to select the designed players for forward position
It defines the budget for forward as static const
You are given in “Players.txt” the list of player names, teams, positions, price and points in previous season. You have to parse this file to populate the vectors of players of type goalkeeper, defender, midfielder and forward.
When overriding selectPlayer method at each derived class, you must count the available budget for that position and substract the amount of money you spent for previous players taking into consideration that you can select exactly only 2 goalkeepers, 5 defenders, 5 midfielders and 3 forwards.
You are given some handouts of sample code to read from/write to a file and to insert to/ delete from vectors.
Write the final squad choice into file “Squad.txt” as follows:
*****************************
The selected Goalies are:
*****************************
Hugo Lloris (Spurs)
Heurelho Gomes (Watford)
*****************************
The selected Defenders are:
*****************************
Kyle Walker (Man City)
Daley Blind (Man Utd)
Hector Bellerin (Arsenal)
Alberto Moreno (Liverpool)
Seamus Coleman (Everton)
*****************************
The selected Midfielders are:
*****************************
Dimitri Payet (West Ham)
Oscar (Chlesea)
Sadio Mane (Liverpool)
Anthony Martial (Man Utd)
Christian Eriksen (Spurs)
*****************************
The selected Forwards are:
*****************************
Sergio Aguero (Man City)
Jermain Defoe (Sunderland)
Harry Kane (Spurs)
