Create a class polynomial that is used to evaluate a polynomial function of x:
P(x) = a0 + a1x + a2x + ⋯ + an−1xn−1 + anxn
The coefficients ai are floating-point numbers, the exponents of x are integers, and the largest exponent n—called the degree of the polynomial—is greater than or equal to 0. The class has the attributes
■ degree —the value of the largest exponent n
■ coefficients —an array of the coefficients ai
and the following methods:
- Polynomial (max) —a constructor that creates a polynomial of degree max whose coefficients are all 0
- setConatant (i, value) —Sets the Coefficient ai to value
- evaluate (x) — returns the value of the polynomial for the given value x
For example, the polynomial
P(x) = 3 + 5x + 2x3
is of degree 3 and has coefficients a0 = 3, a1 = 5, a2 = 0, and a3 = 2. The invocation evaluate (7) computes 3 + 5 × 7 + 0 × 7 + 2 = 73, which is 3 + 35 + 0 + 686, and returns the result 724.

Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class.

- Implement a class named Animal has two private member variables: name of type string and numLegs of type int, and has the following member functions: • setName—Function to set the name • setNumLegs—Function to set the number of animal legs • getName—Value-returning function to return the name • getNumLegs—Value-returning function to return the number of animal legs • speak()—Value-returning function to return the empty string • move()—Value-returning function to return the empty string • print()—Outputs the data stored in the instance variables with the appropriate titles • Constructor with parameter—Sets the values of the instance variables to the values specified by the user, in default: sets name to the empty string and number of legs to 0 2. Using an Animal class as a base class, implement two derived classes simulating a Cat and Dog, each redefining three functions constructor, speak(), move() to represent each animal the most suitable. 3.

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…arrow_forwardThis is an object oriented programming question The code should be in C++ language Create a class Student having a private data members S_ID, S_Name and S_CGPA.
