# A-level Computing/AQA/Paper 1/Skeleton program/AS2017

This is the skeleton code for the AQA AS Paper from 2017. This code is useful for those retaking, and can also be used as a practise for those taking a newer paper.

This is where suggestions can be made about what some of the questions might be, and how they can be solved in different programming languages. If you see that a solution to a question is missing in a language you use, be bold and add it!

Please be respectful and do not vandalise or tamper with the page, as this would affect students' preparation for their exams!

## Make Sure The Number of Years Entered Is Valid

### VB.NET

```    Function GetHowLongToRun() As Integer
Dim Years As Integer
Dim Valid As Boolean = False

```

### Fire

```Function GetHowLongToRun() As Integer

## Crop Virus

### C# Solution

```//minor edit to the simulate summer subroutine
// James Barlow BTC
static void SimulateSummer(char[,] Field)
{
Random RandomInt = new Random();
int RainFall = RandomInt.Next(0, 3);
int Virus = RandomInt.Next(0, 5);
int PlantCount = 0;
if (RainFall == 0)
{
PlantCount = 0;
for (int Row = 0; Row < FIELDLENGTH; Row++)
{
for (int Column = 0; Column < FIELDWIDTH; Column++)
{
if (Field[Row, Column] == PLANT)
{
PlantCount++;
if (PlantCount % 2 == 0)
{
Field[Row, Column] = SOIL;
}
}
}
}
Console.WriteLine("There has been a severe drought");
CountPlants(Field);
}
if (Virus == 0)
{
PlantCount = 0;
for (int Row = 0; Row < FIELDLENGTH; Row++)
{
for (int Column = 0; Column < FIELDWIDTH; Column++)
{
if (Field[Row, Column] == PLANT)

## Adding Rocks to the Simulation

Currently the rocks are defined as a constant but not used - we can either allow the user to enter a number of rocks to be randomly placed, or add a random number of rocks to the field.

### VB.NET Solution

```Function CreateNewField() As Char(,)
Dim Row As Integer
Dim Column As Integer
Dim Field(FIELDLENGTH, FIELDWIDTH) As Char
Dim AmountOfRocks As Integer = 0

Console.Write("How many rocks should be in the field: ")    'Ask user for input
Try                                                         'Try/Catch to ensure correct datatype
Catch ex As Exception
Console.WriteLine("Invalid entry: simulation will continue without rocks.")
End Try

For Row = 0 To FIELDLENGTH - 1
For Column = 0 To FIELDWIDTH - 1
Field(Row, Column) = SOIL
Next
Next

Row = FIELDLENGTH \ 2
Column = FIELDWIDTH \ 2
Field(Row, Column) = SEED

For x = 1 To AmountOfRocks
Row = Int(Rnd() * FIELDLENGTH)
Column = Int(Rnd() * FIELDWIDTH)
If Field(Row, Column) = SOIL Then
Field(Row, Column) = ROCKS
Else
Console.WriteLine("Rock #{0} wasn't placed as it would have replaced the seed!", x)
End If
Next
Return Field
End Function
```

### Java Solution

```JAVA:
static void instertRocks(char[][] Field)
{ Random RandomInt = new Random();
int Row = 0;
int Column = 0;
int rocknum;
for (Row = 0; Row < FIELDLENGTH; Row++)

do{
Row = RandomInt.nextInt(FIELDLENGTH);
Column = RandomInt.nextInt(FIELDWIDTH);
} while(Field[Row][Column] == ROCKS);
Field[Row][Column] = ROCKS;
}

## Changing the seed position

This includes either allowing the player to set exact coordinates of the seed (which should also implement column letters), or spawn the seed in a random position.

### C# Solution

```		static void CreateNewField(char[,] Field){
//added onto the bottom of CreateNewField() Subroutine.
if (!SpecificSeedPlacement()) {
Row = FIELDLENGTH / 2;
Column = FIELDWIDTH / 2;
Field[Row, Column] = SEED; //places 1 seed in the middle of board.
}
else {
int[] Placement = new int;
SetSeedPlacement(ref Placement); // defines where user wants to place seed.
Field[Placement, Placement] = SEED;
}
}

static bool SpecificSeedPlacement() {
Console.WriteLine("Would you like to Place the seed in a specific square? Y/N");
if (input == "Y" || input == "y") {
return true;
}
else {
return false;
}
}

static void SetSeedPlacement(ref int[] Placement) {
Console.WriteLine("Where would you like to place the seed? Enter (X,Y) coordinate");
bool correct = false;
do {
string tempinput = Console.ReadLine().Replace(" ", "").Trim('(', ')'); //removes space and brackets
string[] input = tempinput.Split(','); //Splits string into an array

if (Convert.ToInt32(input) >= FIELDLENGTH || Convert.ToInt32(input) < 0 || Convert.ToInt32(input) >= FIELDWIDTH || Convert.ToInt32(input) < 0) { //checks if array is out of bounds
correct = false;
Console.WriteLine("You have enter a value that is invalid. Please Try Again.");
}
else {
Placement = Convert.ToInt32(input); //set the referenced 'Placement[]' array to user input
Placement = Convert.ToInt32(input);
correct = true;
}
} while (!correct);
}
```

```i have found a simpler solution that doesn't require much coding

### VB.Net Solution

Within `Function CreateNewField()`, below the code that selects the number of rocks if that is in use.

```Console.Write("Should the seed position be centre (C), random (R), or at specific coordinates (S)? C/R/S: ")
Field = PlantFirstSeed(Field, SeedPosition)
```

```Function PlantFirstSeed(ByVal Field As Char(,), ByVal SeedPosition As Char) As Char(,)
Dim Row, Column As Integer
Dim RowValid, ColumnValid As Boolean
Select SeedPosition
Case "C":
Console.WriteLine("Planting seed in the centre of the field!")
Case "R":
Console.WriteLine("Planting the seed in a random location")
Row = Int(Rnd() * FIELDLENGTH)
Column = Int(Rnd() * FIELDWIDTH)
Field(Row, Column) = SEED
Return Field
Case "S":
Do
Console.Write("Enter the X coordinate: ")
If Row >= 0 And Row <= FIELDWIDTH Then
RowValid = True
Else
End If
Loop Until RowValid = True
Do
Console.Write("Enter the Y coordinate: ")
If Column >= 0 And Column <= FIELDLENGTH Then

Case Else:
Console.WriteLine("Invalid input, defaulting to centre position")
End Select
Row = FIELDLENGTH \ 2
Column = FIELDWIDTH \ 2
Field(Row, Column) = SEED
Return Field
End Function
```

### Python Solution

This solution will require that you add `import random` to the start of the program.

```def CreateNewField():
Field = [[SOIL for Column in range(FIELDWIDTH)] for Row in range(FIELDLENGTH)]
Row = FIELDLENGTH // 2
Column = FIELDWIDTH // 2
Valid = False
while not Valid:
SelectPosition = input("Do you want the starting seed position to be the centre (C), random (R) or coordinates you select (S)?\nC/R/S: ")
if SelectPosition == "C":
Valid = True
print("The seed will be planted in the centre")
elif SelectPosition == "R":
Valid = True
Row = random.randint(0, FIELDWIDTH)
Column = random.randint(0, FIELDLENGTH)
print("The seed will be planted at the random coordinates ({}, {})".format(Row, Column))
elif SelectPosition == "S":
try:
x = int(input("Enter the x coordinate: "))
y = int(input("Enter the y coordinate: "))
if x > FIELDWIDTH or x <= 0:
print("Invalid x coordinate entered, please try again.")
elif y > FIELDLENGTH or y <=0:
print("Invalid y coordinate entered, please try again.")
else:
Valid = True
Row, Column = y-1, x-1
except ValueError:
print("An invalid value was entered, please try again.")
Field[Row][Column] = SEED
return Field
```

### Java Solution

```static void CreateNewField(char[][] Field)
{
Random RandomInt = new Random();
int Row = 0;
int Column = 0;
for (Row = 0; Row < FIELDLENGTH; Row++)
{
for (Column = 0; Column < FIELDWIDTH; Column++)

## Intelligent File Opening

When the program loads a file, if the user does not include the ".txt" extension, ensure that it is automagically added.

### C# Solution

```		static void ReadFile(char[,] Field){
string FileName = "";
string FieldRow = "";
Console.Write("Enter file name: ");

// These two lines are the only changes

FileName = FileName + ".txt";

//-

try {
for (int Row = 0; Row < FIELDLENGTH; Row++) {
for (int Column = 0; Column < FIELDWIDTH; Column++) {
Field[Row, Column] = FieldRow[Column];
}
}
CurrentFile.Close();
}
catch (Exception) {
CreateNewField(Field);
}
}
```

### Delphi/Pascal Solution

```Function ReadFile() : TField;
Var
Row, Column : Integer;
FileName : String;
FieldRow : String;
CurrentFile : Text;
Field : TField;
Begin
Write('Enter file name: ');
if RightStr(filename,4)<>'.txt' then     //StrUtils must be used
filename:=filename+'.txt';
Try
AssignFile(CurrentFile, FileName);
Reset(CurrentFile);
For Row := 0 To FIELDLENGTH - 1 Do
Begin
For Column := 0 To FIELDWIDTH - 1 Do
Field[Row][Column] := FieldRow[Column + 1];
End;
CloseFile(CurrentFile);
Except
Field := CreateNewField();
End;
End;
```

### Java Solution

```  static void ReadFile(char[][] Field) {
String FileName = "";
String FieldRow = "";
Console.print("Enter file name: ");
if (FileName.contains(".txt")) {
FileName = FileName;
}
else {

}
}
FileHandle.closeFile();
}
catch(Exception e){
CreateNewField(Field);
}
}
//Inder Panesar 15/03/2017
```

### Python Solution

```def ReadFile():

```

### VB.NET Solution

```'adds .txt if required, but ignores other file types for now. Add into readfile subroutine (and possibly the saving one too while you're at it)
If Right(FileName, 4) = ".txt" Then
FileName = FileName
Else
FileName = String.Concat(FileName, ".txt")
End If
```

## The rows are numbered but not the columns. Fix this columns as letters.

### C# Solution

```        static void Display(char[,] Field, string Season, int Year)
{
//base 62
char[] alphabet = new char[]
{
'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f','g','h','i','l','m','n','m','o','p','q','r','s','t','u','v','w','x','y','z'

for (int Row = 0; Row < FIELDLENGTH; Row++)
{
for (int Column = 0; Column < FIELDWIDTH; Column++)
{
Console.Write(Field[Row, Column]);
}
if (Row <= 9)
Console.WriteLine("| " + String.Format("{0,3}", Row));
else
Console.WriteLine("| " + String.Format("{0,3}", alphabet.GetValue(Row - 10)));
}

{
if (Column <= 9)
Console.Write(Column);
else
Console.Write(alphabet.GetValue(Column - 10));
}
Console.WriteLine();
}
```

### C# Solution 2 (an esaier on that requires less work and looks cooler!)

```  static void Display(char[,] Field, string Season, int Year)
{
Console.WriteLine("Season: " + Season + " Year number: " + Year);
String alphabet = "abcdefghijklmnopqrstuvwxyzABCDEFGHI";
```
```           for (int column = 0; column < FIELDWIDTH; column++)
{
Console.Write(alphabet[column]);
}
Console.WriteLine();
for (int Row = 0; Row < FIELDLENGTH; Row++)
{
for (int Column = 0; Column < FIELDWIDTH; Column++)
{
Console.Write(Field[Row, Column]);

}
Console.WriteLine("| " + String.Format("{0,3}", Row));

}
}
```

### C# Solution 3 (Solution 1 but uses vertical numbers instead of base 62 *works for field sizes larger than 62)

```static void Display(char[,] Field, string Season, int Year)
{
Console.WriteLine("Season: " + Season + " Year number: " + Year);

for (int Row = 0; Row < FIELDLENGTH; Row++)
{
for (int Column = 0; Column < FIELDWIDTH; Column++)
{
Console.Write(Field[Row, Column]);
}
Console.WriteLine("| " + String.Format("{0,3}", Row));
}

for (int Column = 0; Column < FIELDWIDTH; Column++)
{
Console.Write("-");
}
Console.WriteLine();

int count = -1;
for (int Column = 0; Column < FIELDWIDTH; Column++)
{
if (Column % 10 == 0)
count++;
if (Column <= 9)
Console.Write(Column);
else
Console.Write(count);
}
Console.WriteLine();

count = 0;
for (int Column = 0; Column < FIELDWIDTH; Column++)

count++;
if (Column <= 9)
Console.Write(" ");
else
Console.Write(Column - (count * 10) + 10);
}
Console.WriteLine();
}
```

### Pascal Solution

#### concerned by both the above solutions for these reasons
#### random ranges incorrect in both cases

## the random ranges can be changed if the question demands it, it is only there if you need
## it, as this is more of a template of code than a real answer.

#### no need to loop through every column when only one column is being eaten

## the loop i use is scanning the field for the co-ordinates that the desired column is
## located in.

#### no need to return field on both paths

## I return the field on both paths because of the way i was taught, in the sense that a
## function must return something, regardless of what path it takes. its also added because
## its to make sure that it returns something on both paths

## Implement a 1 in 40 chance of a Meteor Storm occuring, which spawns 2 meteors in the field, and sets the whole field on fire, ending the simulation.

### C# Solution

```Place a random chance to call this function (I used 1/40 chance, can be adjusted) inside of all of the seasons (optional, can just be one)

Also, if you have placed a validation for getting a response, create a boolean, and place the "End of Simulation, run again or end?" code inside of an if statement, and if there is a meteor shower, set a global variable to True, and it will not allow the option to continue, just end. E.g.

if (meteorShower == false)
{
Console.Write("Press Enter to run simulation for another Year,\nOr input X to stop, or S to save the current field to a file and end: ");
....
else
{
Console.WriteLine("Unfortunately your field burned in the midst of the meteor shower,");
Console.WriteLine("The end of the world has ocurred.");
Console.WriteLine("You cannot save or continue from this disaster.");
goodResp = true;
Continuing = false;
}

Below is the function for the Meteor Storm:

static void MeteorStorm(char[,] Field)
{
Console.WriteLine("A LARGE METEOR SHOWER HAS CAUSED THE END OF THE WORLD!");
//Sets the whole field on fire
for (int Row = 0; Row < FIELDLENGTH; Row++)
{
for (int Column = 0; Column < FIELDWIDTH; Column++)
{
Field[Row, Column] = FIRE;
}
}

int FirstPos, SecondPos;
Random RandomInt = new Random();
for (int i = 0; i < 2; i++)
{
//The following adds METEOR in a 5x5 area, the centre being at (FirstPos, SecondPos)
FirstPos = RandomInt.Next(4, FIELDLENGTH - 4);
SecondPos = RandomInt.Next(4, FIELDWIDTH - 4);
Field[FirstPos, SecondPos] = METEOR;
Field[FirstPos, SecondPos + 1] = METEOR;
Field[FirstPos, SecondPos - 1] = METEOR;
Field[FirstPos, SecondPos + 2] = METEOR;
Field[FirstPos, SecondPos - 2] = METEOR;
Field[FirstPos + 1, SecondPos] = METEOR;
Field[FirstPos + 1, SecondPos + 1] = METEOR;
Field[FirstPos + 1, SecondPos - 1] = METEOR;
Field[FirstPos + 1, SecondPos + 2] = METEOR;
Field[FirstPos + 1, SecondPos - 2] = METEOR;
Field[FirstPos - 1, SecondPos] = METEOR;
Field[FirstPos - 1, SecondPos + 1] = METEOR;
Field[FirstPos - 1, SecondPos - 1] = METEOR;
Field[FirstPos - 1, SecondPos + 2] = METEOR;
Field[FirstPos - 1, SecondPos - 2] = METEOR;
Field[FirstPos + 2, SecondPos] = METEOR;
Field[FirstPos + 2, SecondPos + 1] = METEOR;
Field[FirstPos + 2, SecondPos - 1] = METEOR;
Field[FirstPos + 2, SecondPos + 2] = METEOR;
Field[FirstPos + 2, SecondPos - 2] = METEOR;
Field[FirstPos - 2, SecondPos] = METEOR;
Field[FirstPos - 2, SecondPos + 1] = METEOR;
Field[FirstPos - 2, SecondPos - 1] = METEOR;

## Implement a 10% chance of Tornado in Autumn where Plants are destroyed and Seeds and Rocks are randomly rearranged in a 10x10 grid

Random Rand = new Random();
int row = Rand.Next(FIELDLENGTH - 10);
int col = Rand.Next(FIELDWIDTH - 10);

Note - Add this code into 'Initialise Field Void' just under Console.WriteLine("| " + String.Format("{0,3}", Row));

Compact version - The 4 'for' statements can be reduced to 2 as they both carry out the same function.

for (int Row = 0; Row < FIELDLENGTH; Row++)
{
Field[Row, 0] = ROCKS;
Field[Row, FIELDWIDTH - 1] = ROCKS;
}
for (int Column = 0; Column < FIELDWIDTH; Column++)

## Implement Season 0, i.e. show the state of the field when the seed is sown - at the start of Spring

[i.e. When the simulation starts, the first field shown is the state of the field at the END of Spring. If you start, for example, with the TestCase.txt file, you will not see the field as it is in the TestCase.txt file, but only once Spring has sprung. This amendment requires the simulation to show the point when Spring starts and then continues as before. Thus, any test file used as the starting point will be shown as Season 0 (to confirm that the field state is as it should be when the test file is read, and the simulation then continues. Hope this is a clearer explanation. Apologies if this has simply muddied the water.]

I've read this at least 40 times and I still have no idea what this question means.

I think this will come up - Excellent question.

#By Ethan Leith

{{CPTAnswerTabEnd}}For both of these previous solutions as FIELDWIDTH and FIELDLENGTH are no longer global variables, they need to be returned back to the main program and passed to every function that uses them.
