The private members of a class may be directly accessed from function "main"
T F
The public members of a class may be directly accessed from functions that are inside (part of the class
C++ language (Composition problem)
Given the following two classes A and B, where all member functions have been fully implemented inline.
class A { public: void f(int arg) { data = arg; } int g() { return data; } private: int data; }; class B { public: A x; }; int main() { B obj; // ... write code here return 0; }
a. Insert the code in the main() function that assigns integer value 99 to the “data” member of obj, which is a B class object).
b.Write the code to display the value (i.e., 99) that has just been assigned to the obj.
c. Note that only a single object obj of B class is declared. How many times are constructors called? If more than one constructor is called, in what order are they called?

- PROGRAMMING LANGUAGE: C++ Write a complete C++ program with the following features.a. Declare a class Time with two fields, hour and minute.b. Provide appropriate constructors to initialize the data members.c. Overload the pre and postfix increment operators (using memberfunctions) to increment the minutes by one. Also make sure if m inutes are59 and you increment the Time it should update hours and minutesaccordingly.d. Provide a function display() to display the hours and minutes.e. In main(), create objects of Time, initialize them using constructors andcall the display functions.f. Test the following in your main:a. T3= ++T1;b. T4=T2++;arrow_forward.

Create a constructor for assigning value to R and a method "int compare(Circle c)" for comparing the radii.

- c++ Friend function concepts Do not use operator overloading Write a Program to design a class complex to represent complex numbers and an input method "void input(float X, float Y)" for setting the values of complex number. Class should use an external friend function "friend complex sum (complex, complex);" to add two complex numbers and should return an object of type complex representing the sum of two complex numbers. Write another method "void show (complex c)" to show the final summation.arrow_forwardReturn type_________________ indicates that a function will perform a task but will not returnany information when it completes its task.arrow_forwardC++ simple friend function. Create a C++ class called cube that calculates the volume of a cube. Use appropriate accessors (getters) and mutators (setters), constructors, etc. Your program must also include a friend function that will sum the volume of two cube class instances. Output the individual volumes of each of the two cube classes and then the total volume from the friend function.arrow_forward
- C++ PROGRAM STRING MANIPULATION Create a class Class1 with a string data member ‘paragraph’. Provide a constructor and getParagraph() method in the class. The constructor just assigns NULL to the data member. getParagraph() method must read a paragraph from user. The paragraph should contain at least 30 words. If there are less than 20 words, the program must ask user to enter paragraph again. Create another class Class2, and make it a friend of the class Class1. Provide a function getSubString(Class1 &obj1, int startIndex, int lastIndex) with return type string in the class Class2 which accepts an object of class Class1 (by reference) and two integers. The getSubString() function should return the substring starting from location startIndex and ending at location lastIndex. Class2 must also contain a store() function that stores the substring in a file. Print screenshot of substring stored in file as well.arrow_forwardDefine a class named "Student" with member variables int RollNo and string Name. Add getter and setter functions. Inside main function create one object of the class and use getter and setter function to give values and display the object. CPP language.arrow_forwardUsing C++ Create a class named employee with name(type string) and points (type double).

Example of friend funtion #include <iostream> using namespace std; class Box { double width; public: friend void printWidth( Box box ); void setWidth( double wid );}; // Member function definitionvoid Box::setWidth( double wid ) { width = wid;} // Note: printWidth() is not a member function of any class.void printWidth( Box box ) { /* Because printWidth() is a friend of Box, it can directly access any member of this class */ cout << "Width of box : " << box.width <<endl;} // Main function for the programint main() { Box box; // set box width…arrow_forwardc++ program. Construct a class named Student consisting of an integer student ID number and a double-precision grade point average. The constructor for this class should initialize the ID number to 111111 and the grade point average to 0.0. Include an accessor function to display all data values. Note: Include the class constructed in the context of a complete program. Your program should declare two objects of type Student and display data for the two objects to verify operation of the class function.arrow_forward13.
