(Difficulty Level 3)In the game Flick Fleet, players undertake space combat by flicking a six sided die at other ships.
There is an object called SpaceShip, where ships have a type corresponding to: Destroyer, Cruiser, Bomber, or Fighter. This object has a method called:
get_ship_type(): Returns a string that corresponds to the type of ship (e.g. "Destroyer", "Cruiser", "Bomber" or "Fighter")
Each ship has different regions that have a corresponding number between 1 and 5.
Fighter - Hull (1), Engines (2)
Bomber - Hull (1), Engines (2), Shield Generator (3)
Cruiser - Hull (1), Engines (2), Shield Generator (3), Defense Grid (4)
Destroyer - Hull (1), Engines (2), Shield Generator (3), Defense Grid (4), Engineering (5)
Write a function called laser_attack that takes in as its parameters a ship of type Ship, and an integer value between 1 and 6.
This function should return true if the number passed in the second parameter corresponds to a region possessed by the ship…

- void Date: addDays (int n); void Date: subtractDays(in n); The addDays method will add n number of days to the current date that's stored in Object's data. For example, object hold 4/21/2022 as the date and if user of this object calls addDays (10) method, it will add 10 days to 4/21/2022 giving a new date of 5/1/2022. There can be more complicated scenarios if you add a lot of days (for example hundreds of days) due to possible rollover of year and months. You can limit number of days to be added to 100. Just like addDays, subtractDays method will subtract number of days from the current date. Provide implementation of both functions in the class. Also modify your main function as follows:arrow_forwardint grades[100]; int i; for (i=0;i <= 100;i++) { grades[i) = 100; } The above C++ code is the proper way to initialize the grades array, TRUE or FLASE True Falsearrow_forwardUse java See the image for requirementsarrow_forward

- 3. Magic Square: Create a class MagicSquare that prompts the user for a positive odd integer size, generates a normal magic square of order size, and prints it with numbers right-justified and aligned in evenly-spaced columns. You may assume the numbers in the square are 3 digits or less (i.e. size ≤31). However, each space-separated column should have a width equal to the largest integer in the magic square. (See example transcripts below.) To generate the magic square, use the following algorithm: Assign 1 to our initial current position: the bottom row, middle column. Place each successive value (up to size * size) in the first of the following positions that is unoccupied: (1) one space down and to the right, or (2) one space up. Positions wrap around the sides, top and bottom, as shown in the following example transcripts (user input underlined): Please enter a positive odd integer: 3 492 357 8 16 Please enter a positive odd integer: 5 11 18 25 2 9 10 12 19 21 3 4 6 13 20 22 23 5…arrow_forwardWhat the following code does? int * foo = new int [5]; if (!foo) { ..}arrow_forwardJAVA ONLYPlease create a code that checks if 'user' favourite game is in the top 3 games. if the game is in the top 3 then it should say: "common favourite game" if else then "uncommon favourite game"code: TOP_3_GAMES = {'', 'CALL OF DUTY', 'LEAGUE OF LEGENDS', 'VALORANT'}arrow_forward
