For my new studies head over to the learn branch.
This doesn't works on Windows.
Only Linux/MacOS.
If you want to use the Windows version change the includes and code.(I'm going to open a branch in the future)
Have a great day.
I wroted some explanations over there feel free to read them.
You need G++/GCC for compiling. (MSVC For windows will work too...)
Compiling with Makefile : make
Compiling with G++ Manually : gcc -Wall -Wextra -pedantic client.c -o client && gcc -Wall -Wextra -pedantic server.c -o server
