“atof” function: In C++, the predefined function “atof” is used to convert a string value into a double-precision floating point value; it passes a string literal or character array as an argument and it converts the received value into a double type value; it takes only one parameter as an argument. If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting. In same way, the function will return “0” when the values can’t be able to convert into double data type. Syntax: Syntax for the “atof” function is as follows: double atof (const char* n); In the above statement, “double” represents the return type of the function. “atof” represents the name of the function. “const char*” represents the data type of the passing argument. “n” is a string variable which is required to be converted. Example: The example for the “atof” function is as follows: //change the string literal to a double value. double n = atof ("1258.11E-14 "); In the above line, the string literal “1258.11E-14” is passed as an argument to “atof” and it returns the converted value that is “1.25811e-11”.

Program Plan Intro

“atof” function:

In C++, the predefined function “atof” is used to convert a string value into a double-precision floating point value; it passes a string literal or character array as an argument and it converts the received value into a double type value; it takes only one parameter as an argument.

If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting.

In same way, the function will return “0” when the values can’t be able to convert into double data type.

Syntax:

Syntax for the “atof” function is as follows:

double atof (const char* n);

In the above statement,

“double” represents the return type of the function.

“atof” represents the name of the function.

“const char*” represents the data type of the passing argument.

“n” is a string variable which is required to be converted.

Example:

The example for the “atof” function is as follows:

//change the string literal to a double value.

double n = atof ("1258.11E-14 ");

In the above line, the string literal “1258.11E-14” is passed as an argument to “atof” and it returns the converted value that is “1.25811e-11”.

Add a timer in the following code. public class GameGUI extends JPanel { private final Labyrinth labyrinth; private final Player player; private final Dragon dragon; private Timer timer; private long elapsedTime; public GameGUI(Labyrinth labyrinth, Player player, Dragon dragon) { this.labyrinth = labyrinth; this.player = player; this.dragon = dragon; String playerName = JOptionPane.showInputDialog("Enter your name:"); player.setName(playerName); elapsedTime = 0; timer = new Timer(1000, e -> { elapsedTime++; repaint(); }); timer.start(); } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); int cellSize = Math.min(getWidth() / labyrinth.getSize(), getHeight() / labyrinth.getSize());}

Change the following code so that when player wins the game, the game continues by creating new GameGUI with the same player. However the player's starting position is same, everything else should be reseted. public static void main(String[] args) { Labyrinth labyrinth = new Labyrinth(10); Player player = new Player(9, 0); Random rand = new Random(); Dragon dragon = new Dragon(rand.nextInt(10), 9); JFrame frame = new JFrame("Labyrinth Game"); GameGUI gui = new GameGUI(labyrinth, player, dragon); frame.setLayout(new BorderLayout()); frame.setSize(600, 600); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(gui, BorderLayout.CENTER); frame.pack(); frame.setResizable(false); frame.setVisible(true); } public class GameGUI extends JPanel { private final Labyrinth labyrinth; private final Player player; private final Dragon dragon; private Timer timer; private long…

Create a menu item which restarts the game. Also add a timer, which counts the elapsed time since the start of the game level. When the restart is pressed, the restarted game should ask the player' name (in the GameGUI constructor) and set the score of player to 0 (player.setScore(0)), and the timer should restart again. And create a logic so that if the player loses his life (checkGame if the condition is false), then save this number together with his name into two variables. And display two buttons where one quits the game altogether (System.exit(0)) and the other restarts the game. public class GameGUI extends JPanel { private final Labyrinth labyrinth; private final Player player; private final Dragon dragon; private final ImageIcon playerIcon = new ImageIcon("data/images/player.png"); private final ImageIcon dragonIcon = new ImageIcon("data/images/dragon.png"); private final ImageIcon wallIcon = new ImageIcon("data/images/wall.png"); private final ImageIcon…
