this is a question about arrays and methods

A Game maintains scores for its players in a comma delimited sequential file "scores.txt" with the record structure outlined below.

An example file. It contains the following sample data:

G001,Hot Shot,280

G002,Loose Cannon,650

G003,FireFox,720

G004,Foxxy,100

scores.txt record structure

Field Name	Type
Player Number	String
PlayerName	String
Score	Integer

A menu driven program is required the user create an report and/or search the file..

Menu Format

Game Menu

1. Player Report

2. Search for a Player

3. Score Analysis

4. Exit

The user shall be able to create report, search and do score analysis as often as they like. The program will terminate when exit is selected.

Report Format (for sample data)

Player Name Score Citation

Hot Shot 280 Sluggish Snail

Loose Cannon 650 Bobbing Bobcat

Fire Fox 720 Rocketing Rabbit

Foxxy 100 Sluggish Snail

Note : Player with highest amount of votes (assume 1 only)

Average Score 575

Top Player FireFox

Alongside the score, you must display the appropriate citation for each player, use the table below do to determine the citation.

Table 1

Score	Citation
Less than 400	Sluggish Snail
between 400 and 599	Ambling Armadeillo
Between 600 and 699	Bobbing Bobcat
Between 700 and 999	Rocketing Rabbit
Greater than 999	TurboCharged Cheetah

Search

Allow the user enter a player number, the program will then search the file, and display the players name, and the score for chosen player. If the player is not found display a message stating "No match found".

Example dialogue

Enter Player Number: G002

Player name : Loose Cannon

Score : 650

Score Analysis

A report showing the number of players that score in the above ranges is required. Use an array to store the number in each range.

Range Number in this range

0-399 2

400-599 0

600-699 1

700-999 1

1000 and over 0

Try this:
