The goal of this assignment is to develop an event-based game.
You are going to develop a Pong Game.
The game board is a rectangle with a ball bouncing around. On
the right wall, you will have a rectangular paddle (1/3 of the wall
height). The paddle moves with up and down arrows. Next to the game
board, there will be a score board. It will show the count of
goals, and count of hits to the paddle....
