Using C++ Language (Console Application Only)

9x9 SUDOKU GAME The project is a 9x9 sudoku game. The objective is to fill a 9x9 grid with digits so that each column, each row, and each of the nine 3x3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contains all of the digits from 1 to 9. The project should have a main menu where users can select from a list of options (New Game and Sub-Menus: Easy, Medium, and Difficult; Exit; etc.) Users cannot save games. The project should have a display board with some filled out (depending on difficulty). The project should have at least 1 ready game each for easy, medium and hard difficulties. You can search the internet for sample games and solutions. The project may use indicators (such as A1 (first cell), A2 (second cell), etc.) to tell users where to put the number. The project should show the solution at the end of the game, if not solved. In-Game Timer, Checker and/or Helper are optional. The project should consist of all our learnings in our laboratory. All methods and variable declaration should be properly commented. It should be strictly a console application. If you wish to use advance topics (like fstream and arrays), that are outside the scope of our CS126-8 Curriculum, please indicate it in your source code
