Today I have decided to start practicing a bit of c++ by diving straight into coding - an orderbook.

Why not rust! Well a lot of the borrow, trait-ish semantics are present in c++. With concepts and templates it make dynamic dispatch possible without v-table. A lot of companies in this space works in C++, so is gpu kernel. Also rust’s semantics adds an overhead, I have seen c++ and dealt with c before.

I have got the nasdaq gz file, learned the structure for procressing. I am taking an AI assisted approach.

It started off using conan to setup the repo, and then creating a skeleton for a proper project. Then was asked to prepare some skeleton code needed to know to build this.

This led me to understand:

• template
• lambda expressions, &, =, seen, &seen
• typename
• constexpr

Some of the concepts are understandable, sometime it looks more like rust. Some books on C++, start with borrowing and stuff.
