- I need help writing a C++ code. I need the code to be a class called date that has an integer data members to store month, day, and year. The class should have a three-parameter default constructor that allows the date to be set at the time a new Date Object is created. If the user creates a Date object without passing any arguments, or the values passed are invalid, the default values of 1,1,2001 (i.e, January 1, 2001) should be used. The class should have member functions to print the date in the following formats: 3/15/2020 March 15, 2020 15 March 2020 I also need the program to only accept real values for month and day. By this I mean month 1-12 and date 1- how ever long the month is.INSTRUCTIONS: Write a C++ script/code to do the given problem. Write a class called profileID, which has data members firstName,lastName, age, birthday and ageCompany (the age when you entered in the company). Remember to use set and get methods to access the data members this time. Also, write another class called bonusAward that has a method getBonus()with arguments yos and etype which are both integer data types. This method calculates the bonus received by an employee using this formula: yos*1000 + etype*1000. Write two derived classes, ASE and SE, using multiple inheritance usingprofileID and bonusAward as parent classes. Both classes must have amethod named getyos()that returns the yos of an employee using the formula age–ageCompany; and a method named getetype() which returns a constant based on the employee type. For ASE, the constant is 10 while for SE that constant is 20. Last, write a main program where you instantiate ASE as employee1 and SE as employee2. Get their…in C++ There should be three files: header file containing the definition of class .h, file containing the class implementation should be .cpp, and the driver code (i.e., the main() function) main.cpp Create a class called Complex for performing arithmetic with complex numbers. Write a driver program to test your class. Complex numbers have the form: realPart + imaginaryPart * i where i is √−1.Use double variables to represent the private data of the class. Provide a constructor function that enables an object of this class to be initialized when it is declared. The constructor should contain default values in case no initializers are provided. Provide public member functions for each of the following: a) Addition of two Complex numbers: The real parts are added together and the imaginary parts are added together. b) Subtraction of two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand and the imaginary part of the right…
- Create a class Employee with following data members, name, id, and salary as private datamember. Create array of objects for four employees, compare their salary using operatoroverloading, and display the records of the student who is getting less salary. by c++In c++ ,Write a program which has a class called Character having a character data member. Overload the operator +, - and !. The overloaded+operator should be responsible for adding the ASCII values of two objects of this class, - operator should subtract the ASCII values of two objects and should return true in case two characters are unequal otherwise it should return false. You should make use of constructor to get input from the user.1- Write a class that allows you to define complex numbers in C++ and call it complex. The class contains two private members named real and img. It also has a constructor to initialize its members to values other than zero. Then, write a four methods that implement the basic mathematical operations (+,-.*/) for two complex numbers. 2- The purpose of the method resize() in the IntegerArray class below is to dynamically change the size of the IntegerArray instance. This methid is implemented as follows: 1. create a new array with the desired size 2. copy the data form the old to new one 3. delete the old data 4. Make the old data pointer points to the newly created data 5. update the size field your task is to write the resize() method based on the above five steps. #include int main() { IntegerArray a(2); using namespace std; class IntegerArray { public: a.data[0] = 4; a.data[1] = 2; int *data; a.resize(5); int size; cout size = size; } -IntegerArray() { delete[] data; } void…
- For this assignment *c++ & no ifstream, you need to build a class that contains basic information about students and courses that have those students on the roster. You also need to build a menu that supports basic CRUD functionality for those courses. The requirements are as follows: The student class should contain the following data about a student: Name (dynamic char array) Classification (char) Major (dynamic char array) StudentId (can be an int or a dynamic char array) The course class should contain the following data about a course: Course Name (dynamic char array) Course Code (char array of size 7) Location (char array of size 10) Roster (dynamic student array) The menu program should act as a driver program that manages a dynamically allocated array of courses and allows the user to: Add a course to the list Add students to a course Update a course to change any of the data above including edits to students or adding/removing students from the roster List courses…Write a C++ program, you will create a class called Books to hold the information about the books in a library. The information required for each book is as follows Book Title Author name Publisher Publish year Subject Book ID (identical 5 digits’ number) Implement the following getBookInfo () member function that receives a pointer to a book and fills it up with user data. User input validation is necessary. The user should be properly prompted for each field. void getBookInfo (Books *b) Implement the following printBookInfo () member function. void printBookInfo (Books *b) Your function should print the book in the following format: Book Title : Object Oriented Programming Using C++ Author : Chris M. Szalwinski Publisher : Amazon Year : 2016 Subject : Computer Science Book Id : 00034 Note: You need to add required constructors/destructors, member functions or data members/variables in your program to complete its execution. //Missing lines of codes to be completed by the student }…This lab must be done in C++ Assignment: In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it. In this lab you will write a program to decode a message that has been encrypted. Detailed specifications: Define three classes. Each one should be in a separate file. You can choose to define the class and its functions inline, all in a header file, or have a .h and .cpp file for each class. Abstract base class with the following: A variable to hold an encrypted message. This variable should be a string which is initialized in the constructor. A status variable that will tell whether the message was loaded successfully. A constructor that receives one parameter: a string variable with a file name and uploads its content to the string variable that is supposed to store it. A pure virtual function called decode. This function will be defined in derived classes. A function that prints the message on the…
- Create a simple C++ program with the 3 following classes. Use separate header and source files for each class. Make all of the class members public. Player name char[32] x, y floats sword - Sword * hit points - int max points - int Player() default constructor Player(char *) - constructor that sets the name heal (Flask *) - heals the player if their health is low and the flask passed in has charges. Do not over heal the player. display() prints the name, sword name and current hit points of the player. Sword name char[32] damage - int attack speed - float Sword() default Sword (char *) set the name Flask name char[32] charges (remaining) int health restored per charge - int Flask() In main create an instance of the Player class and 3 objects from the Sword class. All of these objects must be created on the heap by using the new keyword. Give the swords different names, damage and attack speed values. Equip the player with one of the swords by assigning one of the Sword objects to the…1- Write a class that allows you to define complex numbers in C++ and call it complex.

Write public get methods to retrieve the values for length and width. Write a public calculateArea()method and a public calculatePerimeter() method to calculate and return the area of the rectangle and the perimeter of the rectangle. Open the file named MyRectangleClassProgram.cpp. In the MyRectangleClassProgram, create two Rectangle objects named rectangle1 and rectangle2 using the default constructor as you saw in MyEmployeeClassProgram.cpp. Set the length of rectangle1 to 10.0 and the width to 5.0.
