Martin Ivanov student in Glasgow Caledonian, student number is S1630109 made a simple pong game for his programming classes.

The game is just plain code it doesn't have graphics and is created using Visual Studio 2017 with the C++ coding language.

The code used in this game is as follows:


 * 1) include

//includes the header files that i had to use in the code.

//Adds the directions in which the ball can move around the window.

class cBall

{
