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…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…
- PROGRAMMING LANGUAGE :C++ QUESTION; You need to store hiring date and date of birth for Managers and Employees. You need to create a Date class for this purpose. Create objects of Date class in Manager and Employee classes to store respective dates. You need to write print function in Manager and Employee classes as well to print all information of Managers and Employees. You need to perform composition to implement this task. Create objects of Manager and Employee classes in main function and call print function for both objects. ______________________________________________________________ note : print the specific part of code in following ... Print Date class here: Print updated Manager class here: Print updated Employee class here: Print main function here:This is in C++ given main(), define the Team class (in files Team.h and Team.cpp). For class member function GetWinPercentage(), the formula is: teamWins / (teamWins + teamLosses) Use casting to prevent integer division. Ex: If the input is: Ravens 13 3 where Ravens is the team's name, 13 is number of team wins, and 3 is the number of team losses, the output is: Congratulations! Team Ravens has a winning average! If the input is Angels 80 82, the output is: Team Angels has a losing average. The template provided is this: #include <iostream>#include <string>#include "Team.h"using namespace std; int main(int argc, const char* argv[]) {string name;int wins;int losses;Team team; cin >> name;cin >> wins;cin >> losses; team.SetTeamName(name);team.SetTeamWins(wins);team.SetTeamLosses(losses); if (team.GetWinPercentage() >= 0.5) {cout << "Congratulations, Team " << team.GetTeamName() <<" has a winning average!" << endl;}else {cout…CPSC 131: Introduction to Computer Programming IIProgram 3: Inheritance and Interface1 Description of the ProgramIn this assignment, you will make two classes, Student and Instructor, that inherit from asuperclass Person.

Suppose you are working as RA (research assistant) with a Professor who isworking on a project and evaluating complex mathematical equations. Your duty is to assist him, so in thisregard he has assigned a task to you. Your task is to write a oop c++ program to create a class named equation which will have the data members a, b and c which are the coefficients of the quadratic equation. The class will have two more data members namely proot and nroot which stand for the positive root and negative root of the equation. Suppose that variables a, b and c are integers. Where proot and nroot are floats. Input Function to get values of a, b and c Then design a friend function which will determine the proot and nroot of the equation. Create another friend function which will display the values of proot and nroot.
