- Each function inside the class A(n)_ is a virtual function. Provide your thoughts by filling in the blanks.A(n)_ is a class that only contains virtual functions that are pure virtual. Fill in the blanks with your answer to this question.If a class contains at least one pure virtual function, it’s a(n)_________ class.
- when an application uses pointers or references from the base class to call a virtual function, allowing several implementations of the same functionality to use the same code.Which of the following applies to destructors? Choose all that apply. A.) A destructor is a function that automatically gets called when an object of its class falls out of scope. B.) If you create a copy constructor, you must also create a copy destructor. C.) A destructor cannot take any parameters. D.) A destructor cannot return a value.Create a class Distance having a member meter. Now create a friend function named convert() that increments meter by 5 and then convert that meter in kilo meters and return the answer. Call the function in main. Note: use OOP and C++
- The two header files below describe the interface of the base class Person and its derived class Empolyee, respectively. Please implement all the functions declared in these two header files in their corresponding .cpp files. 1. Header file: Person.h #ifndef Person_h #define Person_h #include <iostream> #include <string> #include <new> using namespace std; class Person{ public: //******************Note********* //This interface is by no means complete. Please feel free to // add more functions if needed. The test cases however will only // test the following functions. virtual ~Person(); Person(); //0->SSN, "na"->name, "personal@"->personalEmail, 10->cntPlaces, allocate space to placesVisited and initializes each place to "unknown" Person operator=(const Person& rhs ); // **Minor revision**: changes the return mechanism from by-reference to by-value //copy constructor Person( const Person &clone );…The maximum number of arguments a function can take is 2. A) False B) True, but only when creating a function inside a class C) True D) True, but only when creating a function outside a classC++YOU ONLY NEED TO EDIT date.h, dateOFYear.h, and dateOFYear.cpp date.h | date.cpp | dateOfYear.h | dateOfYear.cpp | dateTest.cpp You have been provided a Date class. Each date contains day and month parameters, a default and a custom constructor, mutator and accessor functions for the parameters, and input and output functions called within operator >> and <<. You will be writing a DateOfYear class, which expands on the Date class by adding a year parameter. This will be achieved via inheritance – DateOfYear is the derived class of the Date base class. In DateOfYear, will need to write… The include guards for the class A default constructor that initializes all parameters to 1 A custom constructor that takes in a month, day, and year to initialize the parameters Mutator and accessor for the year parameter Redefined versions of inputDate and outputDate that takes into account the new year parameter. The driver program, dateTest.cpp, is already set for use with both Date…
- 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: 3.4Hi, I am having trouble with this homework question for my C++ course 1. Implement a Student class. a. Create a class Student with the following private data members:1. name2. exam_1 grade3. exam_2 gradeb. Create all appropriate accessor and mutator functions.c. Assign appropriate access modifiers to insure encapsulation.d. Add a private calc GPA() function that calculates and returns the GPAbased upon the two exam grades.e. Add a public getGrade() function that: 1. Obtains the GPA from the private calc GPA() function.2. Returns a letter grade based upon the numerical GPA value.90 to 100 = A80 to 90 = B70 to 80 = C60 to 70 = D0 to 60 = F f. Test all functions use following main.int main(){Student a;a.setName("David");a.setExam1(90);a.setExam2(80);cout<<a.getName()<<endl;cout<<a.getExam1()<<endl;cout<<a.getExam2()<<endl;cout<<a.getGrade()<<endl;}Create parent class Shapes with protected parameters width and height and function printarea() and a virtual function cal_area(). Create two sub classes Rectangle and Sqaure. In main() create 2 pointers of Shapes and assign Rectangle and Square to it. Call printarea function with the pointers. Note: use OOP C++
