- Explain encapsulation brieflyPoker card in PythonLet the CarteBase class present itself in the context of this exercise. It encapsulates a game card characterized by numerical values for its face and its kind. The possible faces are integers from 1 to 13, with face 1 corresponding to the ace, and faces 11, 12 and 13 corresponding respectively to the jack, the queen and the king. The other faces are simply identified by their number from 2 to 10. The possible grades are integers from 1 to 4 corresponding respectively to the cards of spade, heart, tile and clover. Analyze this class to understand how it works. You are asked to create a class called CarteDePoker that inherits CarteBase and defines or redefines the following methods: force(self) which returns the strength of the card in the poker game. In Poker, cards have the strength of their digital face from 2 to 13, except for the ace which is stronger than the other cards. So we give it a strength of 14.__eq__(self, other) to define operator behavior…InstructionsDefine an enumeration type triangleType that has the values scalene, isosceles, equilateral, and noTriangle.Write a function triangleShape that takes as parameters three numbers, each of which represents the length of a side of the triangle. The function should return the shape of the triangle. (Note: In a triangle, the sum of the lengths of any two sides is greater than the length of the third side.)Write a program that prompts the user to input the length of the sides of a triangle and outputs the shape of the triangle.
- 1- A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b). The class represents the real andimaginary parts as double precision values.Provide a constructor that enables an object of this class to beinitialized when it is instantiated. The constructor should containdefault values.Provide Public member functions for each of the followingarithmetic’s functions (addition – subtraction – multiplication –division), a complex absolute value operation, printing the number inthe form (a,b), printing the real part , printing the imaginary part andfinal overload the == operator to allow comparisons of two complexnumbers.Include any additional operations that you think would be useful fora complex number class.Design, implement, and test your class.Classes, Objects, Pointers and Dynamic Memory Program Description: This assignment you will need to create your own string class. For the name of the class, use your initials from your name. The MYString objects will hold a cstring and allow it to be used and changed. We will be changing this class over the next couple programs, to be adding more features to it (and correcting some problems that the program has in this simple version). Your MYString class needs to be written using the .h and .cpp format. Inside the class we will have the following data members: Member Data Description char * str pointer to dynamic memory for storing the string int cap size of the memory that is available to be used(start with 20 char's and then double it whenever this is not enough) int end index of the end of the string (the '\0' char) The class will store the string in dynamic memory that is pointed to with the pointer. When you first create an MYString object you should…Regular expression to NFA to DFA conversion: Describes the process of taking a unique regular expression, converting that regular expression to an NFA, then converting the NFA into a DFA. Your regular expression must have at minimum two union, two concatenation, and two Kleene star operations. As followed, concatenations of single charaters can be condensed. Your regular expression cannot be a solved problem from any book. You should describe the regular expression with both processes to convert the regular expression to an NFA and the conversion of that NFA into a DFA.
- JAVA: The Plant class has one instance variable called name. Tree inherits from Plant and adds a height instance variable. Flower also inherits from Plant and adds a color variable. All classes have the usual constructors, accessors, mutators and toString. a) Write a Java program segment (not an entire program) that creates one array containing 2 different trees and 2 different flowers created using parameterized constructors. Include a loop that will write out the details of each object in the array. b) Can the tree object in the array call its setHeight method? Give reasons for your answer. If your answer is no, is there some way for this object to call its setHeight method?4. class definition for Friend For the next version of the friends database (coming soon!), we want to use classes rather than dictionaries. Define a Friend class , where each Friend object will store that friend's name, height and favorite foods. The class should have an init method that takes in that friend's name and height. It should have an add favorite_food method that takes a string and adds that string to a set of favorite foods, and a number_of_favorite_foods method that returns the number of favorite foods for that friend. Sample runs should look like: >>> friend1 = Friend ("dweezil", 175) >>> friend1. add favorite food("borscht") >>> friend1.add favorite food("borscht") >>> friend1. add favorite food("bagel") >>> friend1.add_favorite food("banana") >>> friend1.number_of_favorite_foods () 3. >>> friend1.name 'dweezil' >>> friend1.height 175Create a class for handling 3D coordinates (x,y,z) of type integer. Write down all ws2_p5. possible constructors for initialization and copying. By default (x-y%3Dz%3D0), at the time of initialization the user may omit any axis, should be considered as 0. Write the member functions to perform the addition and subtraction operations between two objects. (Use the pointers to handle the objects and use references while passing them between functions).
