Write a back–end class called TUTTable and save it in a file called TUTTable.cpp. This class must have the following structure:Private MembersData Type Name DescriptionTUTCell cTableData[ ][ ] This member will store the cells of the table. It must contain 30 rows and each row should be able to store 100 cells.int cNumberOfRows This member will store the number of rows that contain data.int cNumberOfColumns This member will store the number of columns that contain data.Public MethodsReturn Type Method Signature DescriptionTUTTable() A constructor that must initialise the cNumberOfColumns and cNumberOfRows to zero.TUTTable(const TUTTable &refTable) A copy constructor that must copy the data from the received class to its data members.At the beginning of this method insert the following debug instruction:if (Debug::ACTIVE) {Debug::log("TUTTable","TUTTable","BEGIN of method");} At the end of this method insert the following debug instruction:if (Debug::ACTIVE)…
DiceSet Write a class named DiceSet that contains a list of Die objects. Fields dice a list of Die objects Methods __init__(self, dice_faces) The constructor should instantiate the dice list to an empty list if no parameters are set. The constructor should take a list of integers. Add one die to the dice set for each integer with the number of faces equal to the integer. pop_die(self, value) Remove and return the first die with the given value from the list. add_die(self, die) Adds the given die (of class Die) to the dice list. roll(self) Roll all the die objects in the list of dice and return their sum. die_values(self) Return a list of the int values (last rolls) of the dice in the list. __str__(self) returns a string version of a dice set. Example: "{[d3] 1, [d6] 4, [d12] 5, [d4] 3}"

Observer pattern The PhoneModel class stores a phone number as a list of digits, and the Keypad class has this method: public void simulateKeyPresses(int numKeyPresses)(0 that allows the user to enter digits one at a time then save each digit in the list. The Screen wants to respond to each key being entered. Make the model notify the observers whenever a new digit is entered for the phone number. The first observer prints the newest digit out to the screen The second observer prints "Now dialing 12345678901.." out to the screen (where the number is the number the model has). Only the Screen class can print to the screen The model must be decoupled from the Other classes.
PyCharm Programming! A Game object knows its name and the number of avators is currently has. It is initialized without Avatars objects. It has a method startGame, which initializes an internal empty list of Avator objects. It has a method to add one Avator object at a time to the Game. It also has a method to remove an Avatar object by the Avatar’s name. A Game object also has a method to animate all its current Avatar objects. Furthermore, it has a method to stopGame, which destroys all current Avator objects in its internal list. The Avatar class creates simple human-type Avatars, which have attributes such as name, hair color, height, superpower. An Avatar object can change its hair color and superpower. It also has a method that “animates” the avatar. The animate() method should simply be a print message such as “Hello! I am …! I have…. hair and my super power is….!”, using the Avatar’s object variables. In main program, create 3 different Avatar objects that resemble 3…
