Possible Section Questions[edit | edit source]
Section C Predictions[edit | edit source]
Theory Questions on Skeleton Code:
- The Skeleton Program loads the game data from a binary file. State two reasons why a binary file might have been chosen for use with the Skeleton Program instead of a text file. [2 mark]
The GetIndexOfItem subroutine is used to find the position of an item in Items. The item to find can be specified using either its name or its ID
- Explain what it means if a value of -1 is returned by GetIndexOfItem. [1 mark]
- How does the subroutine GetIndexOfItem know if it should try to find the item using the name or the ID passed to it as parameters? [1 mark]
- What is the time complexity of the algorithm used to find an item in the GetIndexOfItem subroutine? [1 mark]
- There is an error in the code for the Skeleton Program that does not cause a problem when using the data in the game files provided but could cause a problem with alternative game files. Under what circumstances will the GetIndexOfItem subroutine return the index of an item that was not the item being searched for? [2 marks]
- If the Skeleton Program had been designed to use a hash table to store the items it is likely that it would be able to find the position of an item, when given its ID, in less time than the algorithm currently used in the subroutine GetIndexOfItem. [3 marks]
- Explain the steps involved in finding an item in the hash table. You should assume that all the items available in the game have already been successfully added into the hash table. [4 marks]
- Give one reason why a hash table is not a suitable choice to store the items in the Skeleton Program. [1 mark]
A set is an unordered collection of values in which each value occurs at most once. The items in the game can be described using sets.
- The set A contains all the items in the game.
- The set B contains all the items that have “use” in their Commands.
- The set C contains all the items that have “gettable” in their Status.
- The set D contains all the items in the player’s inventory.
- The set E contains all the items which have a Location equal to the CurrentLocation of the player and that have “usable” in their Status.
- The set F contains all the items which have a Location equal to the CurrentLocation.
Four operations that can be performed on sets are union, difference, intersection and membership.
- Explain how the operations can be used with some of the sets A–F to produce the set of items that the player can use in the current game state. [3 marks]
- The set described in the above bullet point is a proper subset of some of the sets A–F. List all of the sets (A–F) that it is a proper subset of. [1 mark]
- Explain why the intersection of sets F and C does not contain all the items that the player can currently get. [1 mark]
- Explain the difference between a subset and a proper subset. [1 mark]
Section D Predictions[edit | edit source]
Programming Questions on Skeleton Program
- The 2018 paper 1 contained one 2 mark question, a 5 mark question, two 9 mark questions, and one 12 mark question - these marks include the screen capture(s). In contrast, the 2017 paper 1 contained a 5 mark question, three 6 mark questions, and one 12 mark question.
- The 2019 paper 1 will contain 4 questions: a 5 mark, an 8 mark question, a 9 mark question and one 13 mark question - these marks include the screen capture(s), so the likely marks for the coding will be 1-2 marks lower.
This list was created based on analysis of the flag files, ZigZag Education suggestions, and suggestions contained on this Wikibooks page. Please add to this list if you can establish any other likely section D questions.
Most likely predictions:
Note that these mark suggestions include marks for screen capture(s).
- Help command (2 marks)
- Allow file name with/without extension (2 marks)
- Examine room (2+ marks)
- Look into next room for a room description if the door is open (5 marks)
- Have to move rug before being able to open the trapdoor (5 marks)
- Drop item (5 marks)
- Fight the guard using the truncheon (use truncheon command) (5 marks)
- Eat command (5 marks - including regenerating health could be 9 marks)
- Save game using save command (5 marks)
- Player has HP + eating regenerates health (9 marks)
- Filling/drinking from containers - eg. the flask and barrel (9 marks)
- Movement history (9+ marks)
- Go command automatically unlocks and opens doors if you have the key (9+ marks)
- Limit inventory space by item size - tiny, small, and medium items (9+ marks)
Other Ideas[edit | edit source]
Ideas waiting to be programmed
- Open and close all doors in the current location
- Create a new location/room
- give an item to the guard i.e. red dice
- add water to the barrel which can then be put in the flask
- Give an option to pick the lock of a door based on percentage chance, if it fails the guard arrests you
- Add benefits to sleeping i.e. higher chance of winning dice
- Save game
- when "use chair" is executed, it states it can't be done, however the file says the guard won't let you sit on his lap. need a fix?
Unlikely, the .gme file has the incorrect instruction attached to the use function of the chair.
The gme file should have "say,The guard won't let you sit on his lap" not "use,The guard won't let you sit on his lap"
its likely this is just a left over piece of data, no surprise as the code is of questionable quality.

History Stack[edit | edit source]
Taken from ZigZag's example questions.
History uses a stack, to allow players to go to previous locations by typing 'go back' or to display previous locations by typing 'history'. You need 2 subroutines: Push, to add a new visited location, and Pop, to remove to last location from the stack and return it. If the stack is empty this should return -1.
Java:
//This class is the stack class that deals with
//all of the pushing and popping.
class History{
int pointer = -1;
int pastPlaces[] = new int[5];
void push(int newLocation)
{
if(pointer == 4)
{
for(int i = 0; i < 4; i++)
{
pastPlaces[i] = pastPlaces[i+1];
}
pastPlaces[4] = newLocation;
}
else
{
pastPlaces[pointer + 1] = newLocation;
pointer++;
}
}
int pop()
{
if(pointer == -1)
{
return-1;
}
else
{
int poppedValue = pastPlaces[pointer];
pastPlaces[pointer] = 0;
pointer--;
return poppedValue;
}
}
}
//These changes to 'playGame' allow for the
//use of the history stack
void playGame(ArrayList<Character> characters, ArrayList<Item> items, ArrayList<Place> places) {
History history = new History();
...
case "go":
moved = go(characters.get(0), instruction, places.get(characters.get(0).currentLocation - 1), history);
break;
...
}
//These changes to go add the past places to the history stack,
//and allow the user to travel 'back'
boolean go(Character you, String direction, Place currentPlace, History history) {
boolean moved = true;
switch (direction)
{
case "north":
if (currentPlace.north == 0) {
moved = false;
} else {
history.push(you.currentLocation);
you.currentLocation = currentPlace.north;
}
break;
case "east":
if (currentPlace.east == 0) {
moved = false;
} else {
history.push(you.currentLocation);
you.currentLocation = currentPlace.east;
}

case "south":
if (currentPlace.south == 0) {
moved = false;
} else {
history.push(you.currentLocation);
you.currentLocation = currentPlace.south;
}
break;
case "west":
if (currentPlace.west == 0) {
moved = false;
} else {
history.push(you.currentLocation);
you.currentLocation = currentPlace.west;
}
break;
case "up":
if (currentPlace.up == 0) {
moved = false;
} else {

you.currentLocation = currentPlace.up;

Answer 1 - Alter Examine function to take in Places as well.
def Examine(Items, Characters, ItemToExamine, CurrentLocation, Places):
Count = 0
if ItemToExamine == "inventory":
DisplayInventory(Items)
elif ItemToExamine == "room":
print(Places[Characters[0].CurrentLocation - 1].Description)
DisplayGettableItemsInLocation(Items, Characters[0].CurrentLocation)
else:
IndexOfItem = GetIndexOfItem...
Answer 2 - alter the selection statement in PlayGame
elif Command == "examine":
if Instruction == "room":
Moved = True
else:
Examine(Items, Characters, Instruction, Characters[0].CurrentLocation, Places)
VB.NET:
Adjust case statement within Playgame subroutine:
Case "examine"
If Instruction = "room" Then
Moved = True
Else
Examine(Items, Characters, Instruction, Characters(0).CurrentLocation)
End If

Create 'time' command.[edit | edit source]
Create 'time' command. It should tell you how many minutes you have been playing. Alternative add the time (eg how many mins) you have been in the game each time you move from room to room - Note: I doubt that they would ask you to do this as it is trivial in some languages and more difficult in others. More realistically it may ask you to count the number of instructions the player has typed throughout the game.

sw.Start();

Create Attack System with Health[edit | edit source]
Add a 'health' attribute to characters that can be changed in the code (or a command could be added for the user to change it).
Create an attacking system that gives a percentage chance to the player and character that takes one from their health if hit.
If the player dies, the game ends. If the other character dies, their items are dropped in the room that the fight occurs in.
