A program is being developed to implement a game for up to six players.
During the game, each player assembles a team of characters. At the start of the game there are 45 characters available.
Each character has four attributes, as follows:
| Attribute | Examples | Comment |
|---|---|---|
| Player | 0, 1, 3 | The player the character is assigned to. |
| Role | Builder, Teacher, Doctor | The job that the character will perform in the game. |
| Name | Bill, Lee, Farah, Mo | The name of the character. Several characters may perform the same role, but they will each have a unique name. |
| Level | 14, 23, 76 | The skill level of the character. An integer in the range 0 to 100 inclusive. |
The programmer has defined a record type to define each character.
The record type definition is shown in pseudocode as follows:
TYPE CharacterType
DECLARE Player : INTEGER
DECLARE Role : STRING
DECLARE Name : STRING
DECLARE Level : INTEGER
ENDTYPE
The Player field indicates the player to which the character is assigned (1 to 6). The field value is 0 if the character is not assigned to any player.
The programmer has defined a global array to store the character data as follows:
DECLARE Character : ARRAY[1:45] OF CharacterType
At the start of the game all record fields are initialised, and all Player field values are set to 0
The programmer has defined a program module as follows:
| Module | Description |
|---|---|
Assign() | - called with two parameters: - an integer representing a player - a string representing a character role - search the Character array for an unassigned character with the required role- If found, assign the character to the given player and output a confirmation message, for example: "Bill the Builder has been assigned to player 3"- If no unassigned character with the required role is found, output a suitable message. |
The save operation is to be extended so that multiple files may be saved as the game progresses. This will allow the user to restore the game from any saved position. The filename must reflect the sequence in which the files are saved.
Describe a method that would allow multiple files to be saved and give an example of two consecutive filenames.
