Hi all my problem is that DEV C++ in fact continue to run previous compiled file, not the current one I'm running very simple example of SW, and when starting a new one (partially obtained via copy and paste from the old one...) and compiling the new one, DEV C++ runs the old version. I closed the compiler and reopened it, finally I also uninstalled and reinstalled it, but the result is still that it runs N-1 version, not N version (also when from N-1 to N it changed drastically) Unexplicable!! Please...
