/* Your .exe file is Windows-specific. To make it run on other OS:
  1. Recompile the source code on the target OS.
  2. Or use compatibility tools like Wine.
*/

/* #==================================================================================
(windows specific means) -> The .exe file is also tied to the architecture of your machine (e.g., 32-bit or 64-bit).
A 64-bit .exe won’t run on a 32-bit system, even if it's Windows.
