added arguments so that a user can change rectangle and delay without recompiling

[Schievel1]

Lets face the sad truth: Not every person on earth has his or her machine ready to compile C on it. Getting nmake requires to download the C++ workload for VS, which is 3GB+.

To make the life of other users a little easier, and since I had the ability to compile C now anyway, I decided to add arguments that change the size and position of the rectangle and also the delay to activate it.

Ignore the .vs folder, this is some stuff Visual Studio added.
