C++ 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.

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…

(The MyPoint class) Design a class named MyPoint to represent a point with x- and y-coordinates. The class contains: Two data fields x and y that represent the coordinates. A no-arg constructor that creates a point (0, 0). A constructor that constructs a point with specified coordinates. Two get function for data fields x and y, respectively. A function named distance that returns the distance from this point to another point of the MyPoint Type.Draw the UML diagram the class. Implement the class. Write a test program that creates two points (0, 0) and (10, 30.5) and displays the distance between them.Further create a class named ThreeDPoint to model a point in a three-dimensional space. Let ThreeDPoint be derived from MyPoint with the following additional features: A data field named z that represents the z-coordinate. A no-arg constructor that constructs a point with coordinates (0, 0, 0). A constructor that constructs a point with three specified coordinates. A…

- What is Static Member?arrow_forwardT/F1. However, implementation classes may be extended, but interface classes cannot.arrow_forwardin c++ Define a new class named “Student” that must inherit from the given User class. This class manages student info: id (integer), name (string) and gpa (double). It must prevent the creation of a Student object with a negative ID or a GPA that is not between the range of 0.0 and 4.0 by generating a BadValueException error. This class will provide at least the following methods: toString method to return a string representation of the Student object in the format of “ID( <id> ) NAME( <name> ) GPA( <gpa> )” Such as ID(1234) NAME(John Smith) GPA(4.00) Note: the GPA must have 2 decimal places. isGPAGreater method that compares its gpa with another student’s gpa.
