There's a Hello World program at the beginning of the Zig Reference Manual. It of course shows how to print things. Many other of these failures could be avoided by reading that document, reading Zig source code in the distribution, looking at issues on Github, reading blogs and watching presentations by Andrew Kelley, etc. Zig is far from a finished project so it's premature to complain about most of the things you are complaining about.
