Question

In computer systems color is represented by RGB format (Red. Green and Blue color components) where each component can hold a value from 0 to 255. Implement all functions and operators given in the following header file: # include using namespace std; class public://Default constructor//Constructor with parameters//Copy constructor//Getters//Setters//a function that increment all components//a print function to print all components//a function to add two private: int red; int green; int blue; Test your class with an appropriate main ()

Here you go champ, I commented the code as far as possible. But still if you can't understand, feel free to comment below
