A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

After checking multiple tutorials I had to take pieces from each of the following to get this to work on my Win10 system:

Basically it uses the steps from the first article, but under the background path from the second article. Neither article on its own worked for me.

Steps:

	#![allow(unused)] // silence unused warnings while exploring (to comment out)

	use sqlx::postgres::{PgPoolOptions, PgRow};
	use sqlx::{FromRow, Row};

	// Youtube episode: https://youtu.be/VuVOyUbFSI0

	// region: Section

	// Start postgresql server docker image:

	#include "HashTable.h"

	#include <stdio.h> // fprintf
	#include <stdlib.h> // exit
	#include <string.h> // memset
	#include <stdint.h> // uint8_t

	void* dmalloc(size_t size) {
	void* p = malloc(size);
	if (p == NULL) {

	Windows Registry Editor Version 5.00

	; Delete directories under HKEY_CURRENT_USER\Console, then run this
	; Examples: https://gist.github.com/P4/4245793

	"WindowAlpha"=dword:000000cd
	"DefaultBackground"=dword:00000000
	; black dgray
	"ColorTable00"=dword:00141414

	var myFlagType string

	func init() {
	const (
	flagValue = "default value is foo"
	flagUsage = "this is my flag explanation"
	)
	flag.StringVar(&myFlagType, "foo", flagValue, flagUsage)
	flag.StringVar(&myFlagType, "f", flagValue, flagUsage+" (shorthand)")
	flag.Parse()
