C ADD ADD

I'm trying to become an expert programmer but in every book I have tried to use, the example code never works with modern compilers.
Has anyone else has this problem?
What the fuck is this?

Terrible advice. GCC is a fucking relic; it supports way too much to be as effective as it could be.

Look at that shit. There's no way it can be more effective at compiling those than a dedicated compiler.
