- In c++ The student class defines the strings studName and studSSN as protected data members. Aconstructor has arguments that initialize the data. The class studentAthlete has a private datamember sport, which describes the sport the student plays. Both classes have a memberfunction identify(). The base class student outputs the student information in the form student studName Social Security Number studSSN The function in the base class should support polymorphism, and the function in the derivedstudentAthlete class should add the information “Sport <sport>”. In the file “student.h”,declareand implement the two classes in an inheritance hierarchy. In a program, initialize an array of five student pointers as follows: student ja(“John Anderson”, “345-12-3547”);student bw(“Bill Williams”, “286-72-6194”);studentAthlete bj(“Bob Johnson”, “294-87-6295”, “football”);studentAthlete dr(“Dick Robinson”, “669-28-9296”, “baseball”); // list of student pointersstudent *stud[] = {&ja,…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…Using C++, Define a class Student with member variables for a student’s name, student number, address and degree. All of these member variables are strings. Add appropriate constructors and accessors for class Student and include the following member functions: • a member function display_info()that overloads the stream insertion operator << to display the values of all the member variables of a student. • a member function calcFee() to calculate the initial registration fee for a student. For undergraduate students the initial registration fee is R500 and for postgraduate students the initial registration fee is R600. All undergraduate student degrees begin with a ‘B’ which will allow you to determine whether a student is an undergraduate or postgraduate student. (a) Implement class Student. (b) Test class Student in a driver program that does the following: • instantiates an object of class Student, with the following details: name: Mary Mbeli student number: 12345678 address:…
- Write a program in C++ that defines a class named StringOps. Declare data members of this class as described below: variable str of data type string. variable size of data type integer which represents the length of the string str. Define member functions in StringOps as given below: parameterless and parameterized constructors that initialize the string variable str. void input():This function accepts a string as input from the user and stores it in str. The length of this string is computed and stored in the variable size. Overload operator + to create a new string obtained by concatenation of two StringOps class objects. The size of this new string should be appropriately set. Overload operator[] to return the character present at the specific index of the string variable str. The index specified begins from 1 and can range upto size. Index can also receive a negative value in which case -1 means the last character of the string variable str. The range in the negative side…Define a struct to represent a product item with the fields: name, ID, price.2) Define two named instances: “Trousers” 012 100 and “Shirt” 345 85.3) Write a function that takes as argument: one struct instance, a new value for thename (string) and new value for price field. The function will overwrite the previous values for the name field and price field in the called struct instance. For example,you create struct instance item_1 with the value from point 2 “Jeans” 1223 50. When you run the function, it will update the name and price fields with the new values from the argument of the function. Make sure to explain what the difference betweenmutable and immutable is, as comments in your Racket file.C++ Q3. Write a program which has a class template for determining the largest and the smallest number from a list of numbers. Use a constructor for input and appropriate data members and member functions in support of your answer
- This is an object oriented programming question The code should be in C++ language Create a class Student having a private data members S_ID, S_Name and S_CGPA. Now create a public member functions void getID(), void getName() and getCGPA() and finally to display all the data members, create a function void display(). In the main(), create an array of student class, size of the array should be taken from user at run time and call all the functions defined in the class. Sample Output: Student 1 Enter ID: 1 Enter Name: Ali Enter CGPA: 2.5 Student 2 Enter ID: 2 Enter Name: Ahmed Enter CGPA: 2.9 Student 3 Enter ID: 3 Enter Name: Zain Enter CGPA: 3.4 Student 1 informationID: 1 Name: Ali CGPA: 2.5 Student 2 information ID: 2 Name: Ahmed CGPA: 2.9 Student 3 information ID: 3 Name: Zain CGPA: 3.4Here is a statement: class temporary { public: void set(string, double, double); void print(); double manipulate(); void get(string&, double&, double&); void setDescription(string); void setFirst(double); void setSecond(double); string getDescription() const; double getFirst()const; double getSecond()const; temporary(string = "", double = 0.0, double = 0.0); private: string description; double first; double second; }; How can I write a definition of the member function manipulate that returns a decimal number as follows: If the value of description is "rectangle", it returns first * second; if the value of description is "circle", it returns the area of the circle with radius first; if the value of description is "sphere", it returns the volume of the sphere with radius first; if the value of description is "cylinder", it returns the volume of the cylinder with radius first and height second; otherwise, it returns the value -1.Create class Employee that has the following pieces of information called first name, last name, day off and salary. Write a C++ program to implement the following functions for three employees: 1- Constructor to initialize data members. 2- Set and get functions for data members 3- Operate decrement operator to decrement the salary when the employee has a day off. 4- Display the results using friend function called Display().
- Not what I need are things like static data members and static member functions.Static data members and static member functions aren't precisely what I'm looking for.One use of the this pointer is to access a data member when there is a local variable with the same name. For example, if a member function has a local variable x and a data member x, then you can refer to the data member as this->x. Use this fact to complete the constructor implementation of this Point class: class Point { public: Point(int x, int y); int get_x() const; int get_y() const; private: int x; int y; }; Not all lines are useful.
