Final assignment need immediate assistance

RogerWang (8)
Using the code that i will post below i need to add in certain functions that I will list in a moment so what I'm asking is can someone give me assistance on how to do this. This is for an assignment that is due at 11 tonight and I am panicking right now.

Here are the functions:
1. DisplayMainMenu: Displays the Main Menu as described above. Performs error checking for possible choices. Returns menu choice as an enumerated type (see below).

2. LoadPlayerRecords : Loads player records from PlayerStats.txt at start up of program.
Input parameters: array of player records to load. Returns: the #of records loaded from the file.

3. WritePlayerRecords: Writes out the player statistics to the PlayerStats.txt file. Input
parameters: array of player records and the # of records to write.

4. DisplayPlayerRecords: Displays the player statistics to the screen in a table format. Input parameters: array of player records and the # of records to display.

5. EnterPlayerRecords: Requests the user to enter a call sign for each player, checks to see if the call sign already exists, if it does then it does nothing, otherwise it creates a new player record for each player. Checks to ensure that both players use different call signs. Input parameters: array of player records and # of records in list. Returns: the updated # of records in list, the index into the list for player 1 and the index into the list for player 2.

6. CheckForExistingCallSign: Checks to see if a call sign already exists in the player record list( if it does then it returns the index to the existing player record otherwise it returns -1).
Input parameters: array of player records, #of records in the list and the call sign. Returns:index of player record (or -1).

7. AssignSymbolsToPlayers: Requests the players to choose a symbol (“X” or “O”) and assigns the symbol to the appropriate player. Input parameters: array of player records, index into the list for player 1 and index into the list for player 2.
8. PlayTicTacToe: Plays the TicTacToe game. Input parameters: array of player records, index into the list for player 1, index into the list for player 2, and # of records in the player record list.

9. UpdatePlayerStats: Updates player 1 and player 2 stats (based on win/loss/tie) using function UpdatePlayerRecord for each player. Input parameters: array of player records, index into the list for player 1, index into the list for player 2, # of records in the player record list and game state (win/loss/tie).

10. UpdatePlayerRecord: Updates an individual player record (win/loss/tie). Input parameters: array of player records, index into the list for player and game state (did player win, lose or tie).

11. BONUS: selectionSort: Sorts the player record list by player’s individual points. Research details on the Selection Sort algorithm. Document in writing (using your own words) how this algorithm works.
