- Develop class Polynomial . The internal representation of a Polynomial is an array of terms. Each term contains a coefficient and an exponent—e.g., the term 2x4has the coefficient 2 and the exponent 4. Develop a complete class containing proper constructor and destructor functions as well as set and get functions. The class should also provide the following overloaded operator capabilities: "Overload the subtraction operator ( - ) to subtract two Polynomial s."(RationalNumber Class) Create a class RationalNumber (fractions) with these capabilities:a) Create a constructor that prevents a 0 denominator in a fraction, reduces or simplifiesfractions that are not in reduced form and avoids negative denominators.b) Overload the addition, subtraction, multiplication and division operators for this class.c) Overload the relational and equality operators for this classIn C++ Syntax for arrays of objects classGrades allCS[15]; //the default constructor is applied to //all elements of this array //to set the number of students in each class to 25 for (i = 0; i < 15; i++) { allCS[i].setNumStudents(25); } //Assume values in all classes. Write the code to print all class averages?
- Assume you have a system with the following (in picture) write the following in c++ (using Inheritance) Implement the above system using inheritance in the best possible way. Keep every object size as small as possible. Implement all methods (setter/getter/constructors and destructors) Note that the region area is 0 while the city is len*width and the country is the sum of their cities. Create array of countries called Arab of 22 countries. Write a function fill that fills the array ArabA Person has a name (just a first name for simplicity) and friends. Store the names of the friends in a string, separated by spaces. Provide a constructor that constructs a person with a given name and no friends. Provide member functions. c++ void befriend(Person p) void unfriend(Person p) string get_friend_names()Define a class named IDProtected Data Member: number - type int pointer (dynamic variable)number has to be 10 digits integer.Appropriate accessor and mutator functions.Default constructor and one argument constructor.Overload the insertion operator << to output ID objects.Overload the extraction operator >> to input ID objects.Add big three to ID class.Please indicate call of big three. Use following main() to test your class.int main(){ ID a(12345678); cout<<a; ID b = a; cin>>a; cout<<a; ID c; c = a; cin>>a; cout<<a; cout<<b; cout<<c;} Output from given main function:ID number: 12345678ID => copy constrcutor is calledEnter id number: 1234ID number: 1234ID => Assignment operator is calledEnter id number: 56789ID number: 56789ID number: 12345678ID number: 1234ID => Destructor is calledID => Destructor is calledID => Destructor is called
