Player Management System using C++ (With Source Code)

Hello, coders. Welcome to the codewithrandom blog. In this article, we will learn how to create a Player Management System using C++ (With Source Code).

A Player Management System is implemented in C++ is a simple console based application which allows users to add, modify, delete, and display player records. It may also provide functionality to search for players based on their attributes, such as ID or name.

This system assists the authorities in managing incoming players. In terms of the project, the user may control their player profiles. He has the ability to look for and update them. This effort also helps to reduce the danger of data loss. When you save a player record, it is automatically saved in text format in the database.

Objective of the System:

The player management system’s goal is to provide an organized and efficient method of managing player records inside a sports organization. Its goal is to centralize and organize player information such that it is easily accessible and retrievable. The system helps administrators to maintain track of players’ personal information, game data, and contact information by allowing them to input, modify, delete, and display player details. The technology may also make it easier to find certain players based on features such as ID or name. The ultimate objective is to improve communication and maintain smooth operations within the sports organization by streamlining the maintenance of player records.

Overview of the UI:

The user will choose an option to perform the operation of their choice. User will then enter a values according to the prompts that will be displayed on the console to perform that operation.

You can directly use this code by copying it in your IDE to understand the working and then can create it by understanding the project.

Now let us understand the code:-

• We will start by writing the header of the code with the required libraries – iostream  (input and output stream), fstream (For File Handling), string (For String Manipulation), stdlib.h (memory management), conio.h (console input/output).
• We will create a class called file and create private data members which will store information about the player – playerid, playerName, age, add, phno (we are not taking int because Mob No. is 10 digit which is outside the range of int), parentName, game, coachn, coachName, dorm (dorm number), bed (bed number).
• We will also create public member functions – 
• The input() function will let the user input the information/details of the user. The details which user will put are – player id number, age, first and kast name, address (city), phone no., parent’s name, game they play, coach name, dorm number, and bed number.
• The output() function will output/print the player details which we entered above using the input() function.
• The retplayername() function will return the player name.
• The retage() function will return the player’s age.
• The radd() will return address.
• The rphno() function will return the phone number of the player. We will take long long as data type as int cannot store the mobile since it is out of range.
• The rparentn() function will return parent name.
• The rgame() function will return game name.
• The rcoachn() function will return coachName.
• The rdorm() function will return the dorm number.
• The rbed() function will return the bed number allotted to the player.
• Now outside the class we will create a function called writeInFile(). This function is used to write the details in the file. It takes details of class instance and append that into the file. It writes the player’s details to a file named “PlayersRecord.txt” in a specific format. For this code snippet – fout<<‘D’; – D will be starting character of Dorm no. in file for unique identification. All Dorm No. will start with D.
• For fout<<‘B’; – B will be the Starting char of every Bed No. for its unique identification.
• Now we will create a function called showAllRecords(). This functions shows all the Players record which we have stored in file. It will read from the file “PlayersRecord.txt”. After reading it will also close the file.
• The deleteInRecords() function is function which deletes the Record of Player from “Playersrecord.txt file” and it can delete the Record of Player using Player Id and Player Name both. If the choice is 1: it asks for Player’s Id else the choice is not 1 here it is 2 as passed by main as 2(deleInRecords(2)): it asks for Player’s Name. It searches the Player’s id and if found it deletes that record.
• The readFile.close(); will be closing the PlayersRecord,txt file.
• The writeFile.close(); will be closing sample.txt file.
• The remove(“PlayersRecord.txt”) function will be deleting Playersrecord.txt file since unmatched(contents which doesn’t need to be deleted) content is copied to sample.txt file.2
• The rename(“sample.txt”, “PlayersRecord.txt”) function will rename sample.txt as PlayersRecord.txt since Sample.txt contains the contents which were not needed to be deleted.
• The countPlayers() function counts the Total number Players available in our Record File (“PlayersRecord.txt”). It uses the string “id” to uniquely identify a record(line) since there is id for every Player. So, No. of Player available in Record is equal to no.of times “id” is found in Record File(“PlayersRecord.txt”). Most of the code will be explained in the source code itself.
• The countPlayersInGame() function counts Total number of Players in all Games here “Basketball”,”TableTennis”,”Cricket”,”Volleyball”,”Hockey”, “Taekwondo”, “Badminton”;. It contains the list of games available for enrollment. We will use for loop and while loop.
• The searchInRecords() function finds the Player record by using the PlayerId, PlayerName,Parents Name, Game, Dorm No. Bed No. It takes the Player Name as from user & returns the details of the player. It searches the Entered Player name in File “PlayersRecord.txt” and returns the record if it is there. If the Player is not found in the file it Returns “Player not found…!!”. We will use a switch case control statement to enter details.
• The clearCompleteDatabase() function is used to completely delete the Player Database. It asks for re-confirmation from user. If the user press “Y” it completely clears the Player’s record.
• The main() function. We will create an object called ‘fileobj’ for the class file. Using the hile loop we will first display the list of menu options on the console. The user will enter the choice. We will use switch case statements to select between choices.
• This sums up our project of Player Management System using C++ (With Source Code).
