Usage

Show instructions

1. Download and compile:

$ g++ -std=c++11 main.cpp unix_functions.cpp windows_functions.cpp -o CheckOS

$ ./CheckOS

Motivation

I needed a way to determine which is the OS where the code is being compiled FROM THE SOURCE CODE (if it's possible), this can be helpful for those projects/programs that need to operate on multiple OS.

Why

So i (and you) can easily write one code.

Problem solved

Need to write different source code for different OS.

Knowledge

The importance and utility of system MACROS.

Improvable

Yes, definitely.
