Employee Class (Medium) Write a class named Employee that has the following member variables: name. A string that holds the employee’s name. idNumber. An int variable that holds the employee’s ID number. department. A string that holds the name of the department where the employee works. position. A string that holds the employee’s job title. The class should have the following constructors: A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position. A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string (""). A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable. Write appropriate mutator functions that…
Create a class Employee a) private and static field nextAvailableID (int): create a static constructor to initialize this field to a random number (hint: you can use Random class). You can assume that IDs are numbers between 1-9999. Since nextAvailableID is static, all the Employee objects will share this field. b) with properties FirstName (string) LastName (string), ID (int): make it read only to allow initializing only with a constructor and then no more. c) Add a constructor to allow setting properties FirstName and LastName. Hint: ID will be initialized to nextAvailableID (make sure to increment nextAvailableID by one) Add ToString Method to display the full name and ID of the employee Then, write a Main method to test your class Employee. Create four Employee objects with references e1, e2, and e3 by providing first and last name of each employee Display the full name and id of each employee - note that each employee will have an automatically generated ID…

TIME CLASS (C++) - Write a time class named timeClass - Write code to demonstrate that it works - The timeclass class will be named timeClass - The class must have these 3 constructors: #1) timeClass(); #2) timeClass(int h, int m, int s); #3) timeClass (string timeIn); - The string constructor must be capable of being separated by colons or blanks time in the 24-hour format: example 23:11:07 or 9:4:9 or 11 31 27 - DO NOT use some system functions for this assignment. You must write the code. - Yes, you can convert from string to integer stoi ( string). - In addition to the constructors, you should supply a set of getters (Accessors) getH, getM getS - In addition to that, add mutators that allow the individual setting of Hours, Minutes and Seconds: setH(int), setM ( int ) setS( int ) Include this setter ( Mutator) setTime( int NumSeconds); - So if I call setTime( 7673) you would know that that is: -- hours, -- minutes and -- seconds seconds = 53 7673 % 60…
(Invoice Class) Create a class called Invoice that a hardware store might use to representan invoice for an item sold at the store. An Invoice should include four data members—a part number (type string), a part description (type string), a quantity of the item being purchased (typeint) and a price per item (type int). Your class should have a constructor that initializes the fourdata members. A constructor that receives multiple arguments is defined with the form:ClassName( TypeName1 parameterName1, TypeName2 parameterName2, ... )Provide a set and a get function for each data member. In addition, provide a member functionnamed getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by theprice per item), then returns the amount as an int value. If the quantity is not positive, it should beset to 0. If the price per item is not positive, it should be set to 0. Write a test program that demonstrates class Invoice’s capabilities
Complete the code for the Student class method called void loadStudent(...) that receives a single string parameter. This string parameter will contain student details in the following format: ’Name’,’Surname’,’Email’,’Age’,’Student Number’ Write the code to separate the string and assign the correct values to the Student class members. Create an overloaded > (greater than) operator in the Student class. The operator will compare the age of two student objects and return the object with the greater age. In main.cpp create a non member function named isFemale. This function will receive as parameter a pointer to a student object. If the last two numbers of the student number is valid numbers (Must be between 0 and 9) the function will return true. Otherwise the function will return false. Overload the default constructor for Student to receive a single string parameter. This string parameter will contain student details in the following format:…
C# (Odd or Even) Write an app that reads an integer, then determines and displays whether it’s odd or even. (Hints: use the remainder operator) (Multiples) Write an app that reads two integers, determines whether the first is a multiple of the second, and displays the result. (Hints: use the remainder operator). Create a class called Date that includes three pieces of information as auto-implemented properties: a month (type int), a day (type int), and a year (type int). Your class should have a constructor that initializes the three fields. Provide a method DisplayDate() that displays the three fields (separated by '/'). Write a test app named DateDemo that demonstrates class Date’s capabilities.
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.
Complete the Appointment class. The class should have the following instance variables, constructors) and instance methods: 1. A properlv encapsulated String instance variable named personName 2. A properly encapsulated String instance variable named day. 3. A properly encapsulated double instance variable named duration 4. A default(no-arg) constructor that sets the per sonName instance variable to "Your Boss", day instance variable to "Monday" and duration instance variable to 1.5. 1. An overloaded constructor that takes two String parameters and one double parameter and sets the instance variables to the values passed in. 2. A getter and setter method for each instance variable. .A method named printAppointment, the method returns a String which contains the concatenation of the instance variables as shown in the sample output
