- Which three actions are obligatory when dealing with classes whose member variables are pointers?C++ assigment: It's a Number Guesser assignment. It asks to 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. This is the code for NumberGuesser class. It is defined entirely in-line in the following file: NumberGuesser.h // NumberGuesser.h // #ifndef NUMBERGUESSER_H #define NUMBERGUESSER_H #include <iostream> class NumberGuesser { protected: int low; int originalLow; int high; int originalHigh; public: NumberGuesser(int l, int h) { low = originalLow = l; high = originalHigh = h; } virtual int getCurrentGuess() { return (high + low) / 2; } virtual void higher() { low = getCurrentGuess() + 1; } virtual void lower() { high = getCurrentGuess() - 1; } virtual…C++ assigment: It's a Number Guesser assignment.

- Can data fields and functions be placed in any order in a class?PPM (Portable Pixmap) use three integers to represent a pixel – this means we can have images with RGB colors. You will create a Pixel class in C++ which has three attributes: red: int green: int blue: int You will create a default constructor that initializes those values to 255, and an overloaded constructor that takes user input to assign the values. The class will also have the following functions: changeRGB (): Takes in three integers to update the red, green, and blue attributes. Returns nothing. printRGB (): Takes in nothing. Prints the red, green, and blue attributes in order with a single space in-between each value. Returns nothing. You will then recreate the art program from Assignment 5 with the following changes: Instead of a 2D array of integers, you will create a 2D array of Pixel object. Don’t be scared! This is similar to creating a 2D array of strings. You will prompt for three color values instead of one – red, green, and blue. These must be stored in a Pixel…Why is destructor function required in class? Can a destructor accept arguments?
