Need help with c++ (1) Define the class ContactNode per the following specifications: Private data members string contactName string contactPhoneNumber ContactNode* nextNodePtr Constructor with parameters for name followed by phone number Public member functions GetName() - Accessor GetPhoneNumber() - Accessor InsertAfter() GetNext() - Accessor PrintContactNode() Ex: If the name is Roxanne Hughes and the phone number is 443-555-2864, PrintContactNode() outputs: Name: Roxanne Hughes Phone number: 443-555-2864 (2) Define main() to read the name and phone number for three contacts and output each contact. Create three ContactNodes and use the nodes to build a linked list. (1st attached image) (3) Output the linked list using a loop to output contacts one at a time. (2nd attached image) Provided template: #include <iostream>using namespace std; class ContactNode {public: /* Declare member functions here */ private: /* Declare data members here */ }; /* Define…

Bank Account Class Part (1) Define a class with the following specification:(a) The class name is BankAccount and it has two private variables: fullName (String) and balance (double). (b) Write a constructor that initializes fullName and balance variables. If balance is negative, then set it to 0.0 and print the message “Invalid balance. Balance is set to 0.0”. (c) Provide a set and get methods to balance variable. In set method, if the supplied balance (parameter) is negative print an invalid message and do not change the balance.(d) Write a method deposit() that has one double input parameter called amount. The method adds amount to the current balance.(e) Write a method withdraw() that has one double input parameter called amount. The method subtracts amount from the current balance.(f) Write method printInfo() that displays the full name on a single line followed by the balance on the next line. Part (2) Write a Java application to test the class you defined in Part (1):(a) Ask…
class first { public: void setX(); void print() const; protected: int y; void setY(int a); private: int x; }; Suppose that class second is derived from class first using the statement: class second: private first which members of class first are private, protected, and public in class second?
"The program instantiates and uses instances of a derived class with default and parameterized constructors. Write A Base Class Declare a class named RealProperty that could be used to describe a piece of real property. It should contain these private fields: streetAddress (string) squareFootage (int) taxes (double) Each field should have a comment documenting what it is for. Add public member functions as follows: The default constructor. The default constructor initializes the fields so that the street address is an empty string and all numeric fields are 0 or 0.0. Implement the default constructor inline using the member initialization list syntax. The constructor that accepts these data: street address (string), square footage (int), and taxes (double). Implement this constructor inline using the member initialization list syntax and call the mutator function for square footage in the body of the constructor. Add mutator member functions to set the fields. One member function for…
Design a class named Employee. The class should keep the following information infields:• Employee name• Employee number in the format XXX-L, where each X is a digit within the range0-9 and the Lis aletter within the range A-M.• Hire date* Write one or more constructors and the appropriate accessor and mutator methods for theclass.Next, write a class named ProductionWorker that extends the Employee class. TheProductionWorker class should have fields to hold the following information:• Shift (an integer)• Hourly pay rate (a double)The workday is divided into two shifts: day and night. The shift field will be an integer valuerepresenting the shift that the employee works. The day shift is shift 1 and the night shift isshift 2. Write one or more constructors and the appropriate accessor and mutator methodsfor the class. Demonstrate the classes by writing a program that uses a ProductionWorkerobject. have to use beginner code because this is an intro class.
i will upvotes unique answer plzz (Use language OOP in c++) Create a class Student with data members age and marks, both of type integer. Provide a parameterized constructor and a set member function to set the data members. The age should be a positive number between 15 and 40 while the marks should be between 0 and 100. Create a class InvalidRange as exception handler of the Student class. Add two private data members (a string and an integer) to theclass InvalidRange. Provide appropriate constructor and get methods for the data members. The string should store the name of the function throwing the exception while the integer should store the invalid value the user has supplied. The student class should throw an exception if any of its member functions attempts to assign an invalid value to the data members. In the main program, create objects of class student, assign valid/invalid values to the data members and catch the exceptions accordingly. Extend the program to have two…

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

You must use C++ as the programming language. Please do the following:Create a program that illustrates C++ classes. Your program should do the following:Write a class named Car that has the following member variables: year (An int that holds the car’s model year. The year must be between 1900-2030 (inclusive)). make (A string that holds the make of the car.) speed (An int that holds the car’s current speed. The speed must be 0 or greater. )In addition, the class should have the following member functions: Constructor - The constructor should accept the car’s year and make as arguments and assignthese values to the object’s year and make member variables. The constructor should initializethe speed member variable to 0. Notice that this constructor will have 2 parameters: one forthe year and one for the make of the Car. When you define a Car object, you will need to send the two arguments the constructor isexpecting:Car myCar(2002, “Jetta”); In the constructor you need to assign a…
