This task is about making a clone of the game "GREED" by Matthew Day.
This game is played on a grid of 79 column by 22 rows of random numbers from 1 to 9. The player location is signified by the '@' symbol.
The object of Greed is to erase as much of the screen as possible by moving around (all 8 directions are allowed) in this grid. When you move in a direction, you erase N number of grid squares in that direction, N being the first number in that direction. Your score reflects the total number of squares eaten.
You may not make a move that places you off the grid or over a previously eaten square.
The game is over if there is no more valid moves.
C++
Windows console version.
