Overview

Usage

• Do Define _CONSOLEWIN in your project settings, if you want your project to work like a console and windows application. The standard output, and input will be redirected to the parent console. You can use cout, cerr, cin, printf, etc.
• Do not define _CONSOLEWIN in your project settings, and you will get a windows application. (Default)

Source code

//Set subsystem to console, just overwrites the default windows subsystem
