Explanation

He really felt your post and thought it was worth sharing on his facebook page and status.

The main program declares an instance of the Simulation Class.

It declares variables for the key information required for the simulation.

The option is to start with the predefined values or to enter the values yourself. If option 1 is selected the variables will be assigned their default value, however if 2 is selected the values entered by the use will be assigned to the variables.

The instance of the Simulation Class will be assigned the values predefined or entered by the user. This will obviously start the simulation and run the code within that class.
