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:
In C++ class SaleItem{public:double getprice();void setprice(double);void setName(string);string getName();double TotalItemsPrice(int);private:double price;string name;}; In the class declaration above, what is the name of the class? Which lines have member access specifiers? Which lines contain data members of the class? Which lines contain accessor functions? Which lines contain mutator functions?
C++ Program: Random Number Guesser. Write a derived class of the NumberGuesser class named RandomNumberGuesser. The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor. It may also override the higher(), lower() and reset() methods as you see fit. To get everyone started off on the same page I have written a NumberGuesser class. It is defined entirely in-line in the following file: NumberGuesser.h (Links to an external site.) https://fog.ccsf.edu/~mluttrel/cs110b/NumberGuesser.h In the current NumberGuesser class the getCurrentGuess() method returns the midpoint of the range of possible values. In your RandomNumberGuesser class the getCurrentGuess() method should return a randomly generated number in the range of possible values. Note that repeated calls to getCurrentGuess() should always return the same value for both classes if neither the higher() or the lower() functions are called. Consider the…
Answer this in C++: In the Student.cpp file and Student.h file, build the Student class with the following specifications: Private data members string name - Initialized in default constructor to "Louie" double gpa - Initialized in default constructor to 1.0 Default constructor Public member functions SetName() - sets the student's name GetName() - returns the student's name SetGPA() - sets the student's GPA GetGPA() - returns the student's GPA Ex. If a new Student object is created, the default constructor sets name to "Louie" and gpa to 1. The output of GetName() and GetGPA() before and after calling SetName("Felix") and SetGPA(3.7) is: Louie/1 Felix/3.7 main.cpp #include <iostream> #include <vector> #include "Student.h" using namespace std; int main() { Student student = Student(); cout << student.GetName() << "/" << student.GetGPA() << endl; student.SetName("Felix"); student.SetGPA(3.7); cout <<…
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() { using namespace std; IntegerArray a(2); a.data[0] = 4; class IntegerArray { public: a.data[1] = 2; int *data; a.resize(5); int size; cout size = size; solve number 2 } -IntegerArray()) { delete[] data;…

Write a C++ program that does the following: Write a class named Student that has the following variables: name - a string that hold the student's name idNumber - an integer that holds the student's id number major - a string that holds the student's major The class should have the following constructors: A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: student name, ID number, and major. A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: student name and ID number. The major should be assigned an empty string (" "). A constructor that assigns empty strings (" ") to the name and major member variables and 0 to the idNumber member variable.

What are the three things that you are required to perform for classes that include member variables that are pointers?
The operator that is required to access members of classes and structs is called: a. Colon operator b. Scope resolution operator c. Operator overloading d. Member access operator e. None of the answers Answer: What is the name of the program that uses and interacts with the class? Answer: By assuming that all libraries are included, replace MYFUNCTION with the proper function name to make the code correct: 001010 111101101 01010101111110 1010101010101 111010101010 0101100 vector> MyVector; int rows= 10, cols = 4; MyVector.MYFUNCTION(rows, vector(cols, 100)); cout << MyVector [0] [1] << endl; for (int i } = 0; i < MyVector.size(); i++) { for (int j 0; j < MyVector[i].size(); j++) cout << MyVector[i][j] << " "; cout << endl;
