PLEASE HELP (AGAIN): Perhaps I am simply in the dark about how to use .h files. I have no file to add. These are the instructions: 1. Write a class to represent Roman numerals. a. The class should have two constructors.: (1) A default constructor (2) A constructor that takes a string as a paramter (i.e., string representing a roman numeral) b. This class should have the following member functions, in addition to the above constructors: (1) set - sets the member variable to the values in the function parameter (2) print - print the converted integer value (3) convert the roman number string to a positive integer (4) print the roman number string c. This class should have two PRIVATE member variables: (1) string to hold the roman numeral string (2) integer to hold the converted value 3. Create: a. a class definition file (*.h) b. a class implementation file (*.cpp) c. a client program to test your class (*.cpp) d. a project for these code files 4. The client program…
Put the client program in a separate file from the class, and divide the class into specification file (fraction.h) and implementation file (fraction.cpp), so your code will be in 3 separate files. Fraction.h #include <iostream>using namespace std; int gcd(int a, int b) { if (a == 0) return b; if (b == 0) return a; if (a == b) return a; if (a > b) return gcd(a - b, b); return gcd(a, b - a);} class Fraction {private: // numerator and denominator int n, d; public: // simplifies the fraction void simplify() { int g = gcd(n, d); n /= g; d /= g; } // default constructor Fraction() { n = 0, d = 1; } // parameterised constructor Fraction(int a, int b) { n = a, d = b; simplify(); } // prints the fration as n/d void print() const { cout << n << "/" << d; } // multiplies 2 fractions and returns it Fraction multipliedBy(Fraction f) const { f.simplify(); Fraction r; r.n = n * f.n; r.d = d * f.d; r.simplify(); return r; } // divides two fraction and…
Implement the Rectangle class as discussed this week. Use the class declaration below. Your job is to implement the functions. Implement the missing functions yourself. class Rectangle{ private: double width; double length; char *name; void initName(char *); public://constructorsRectangle();Rectangle(double, double, char*);//destructor ~Rectangle(); void setWidth(double); void setLength(double); void setWidth(char *); void setLength(char *); void setName(char *); double getWidth() const; double getLength() const; void printName() const { cout << name; }}; A few notes on the functions: initName(char *): this is a private member function. It should be the only function which dynamically allocates a char array to hold the name. setName(char *): this is a public member function which changes the name of the rectangle to a new name. It does not dynamically allocate memory, it only changes name. Demonstrate your class works…

Create a Person class that has the properties: name and age. Override toString so that it displays a Person object like this: Where name is the value of the name property and age is the value of the age property. "<Name: name, Age: age>" Person class should have a natural ordering by age in descending order. Create a Main.java file that: Sorts a List of people using Person’s natural ordering. Uses a custom Comparator with an anonymous class that sorts the List of people by name in ascending order. Uses a custom Comparator with a lambda implementation that sorts the list of people by name in descending order.
Suppose that you have the Object class Employee which is an object that contains Name, Surname and Payment with the respective set and get functions. You will create following functions on 'EmpRW' class, and create a main java class to call them. a. Write a java function that writes on a file named 'emp.txt' by using Formatter Class, this Employee Object. b. Write another java function that reads from the file 'emp.txt' and stores the data as an array of Instances of Employee object. C. Write a function that prints out the name, surname and maximum salary from the Employee list taken from the file. Now write the main java class that takes data by using Input Dialogs, and that uses all of above functions of 'EmpR W' class. e. Write the same functions in a and b by assuming the Employee Object class is serializable, on 'EmpSerR W' class. The name of the file to read and write should be 'emp.bin
