In the last post, I told you how I learned the basics of generating a WAVE file, both in Python and Zig.

Today I set out to learn how to create a WAVE file. I had recently gone through an article about reading and writing wave files in Python, which whet my appetite to do somewhat the same in Zig.

Since last weekend I’ve been toying around implementing a calculator in Zig. One of my favorite algorithms I learned in college from my data structures classes were the shunting yard algorithm to parse and evaluate expressions, converting to the reverse Polish notation.

Today I decided to get some practice using Zig’s data structures from the standard library, building an old friend: a bc style calculator, implementing the algorithms to evaluate reverse Polish notation expressions and converting from infix to that notation.

In my Zig learning journey, I’ve managed to not use allocators for anything yet. I’ve watched this great video of Dude The Builder explaining the basics of allocators in Zig.
