Modify the code above to create a "Favorite Video Game List" program that is contained in three files:
- Game.h
- Game.cpp
- Game_List.cpp
You will need do to these things as you modify the code and put it into the three files:
- Create a class called "Game" (instead of "Movie") that contains 3 private variables ("title", "year", and "rating")
- The "year" is when the game first came out.
- The "rating" should be from 1 to 5 (5 being the best).
- Add the appropriate member functions of the class (setters and getters).
- Continue to use the get_title_upper() function as part of the class, Game, and in the output within the main file, Game_List.cpp.
-
- Add the Default Constructor and Destructor for the class with the member functions of the class.
- Don't forget to add the "include guard" to the .h file
- Use the scope resolution operator correctly for each file.
- Don't use the "using namespace std;" for the main file, Game_List.cpp.
- Instead, use the "using" declaration
- using std::cout;
- using std::endl;
- using std::string;
- etc.
- Instead, use the "using" declaration
