OBJECT ORIENTED PROGRAMMING

Design two grid based games or two block based games in c++

In some cases, the bulk of the project lies in producing a nice user interface, probably using the FLTK graphical library, while the algorithmic content is quite simple. In other cases, the bulk of the work is in devising and implementing the algorithms. Some projects are more difficult than others, but a good policy is to choose one which allows extensibility if you have more time, or a suitable half-way stopping point if it proves to be difficult.

1. Grid based games, ranging from the simple such as Noughts and Crosses through more complex games such as Minesweeper and Battleships. See Levy Computer Gamesmanship pp. 30-39
2. Block based games, such as Snake or Tetris.
3. You can design hangman, pong , tic tac toe

Tool: Dev++, Visual Studio or any of your choice.
