I want to improve my c++ skills, any rec?

Hello, I study Physics and I want to specalise in Computational Physics to make simulation softwar of physical systems, so i want to improve my programming skills.
The harder programs I wrote are simple versions of Snake and Space Invaders.
How can I improve my skills?

Practise a lot. Write world-level programs which can extend to thousand of lines of code, like Yahtzee game (just one example).

For each big program, you will likely gain a tremendous amount of experience.

I want to specalise in Computational Physics to make simulation software of physical systems, so i want to improve my programming skills.

Ask yourself what kind of software requires a lot of physics?

Answer is 3D games, try to make one. Since you already made a snake game, try making it in 3D, that should be a good exercise.

That's a goos idea but i don't know how to approach with graphic interfaces. I've written Snake printing every typeface onthe terminal, updating continously the screen with system("cls").
How can i do a serious 2D/3D interface?

Learn a graphic library, OpenGL or DirectX. There are a lot of tutorials out there that will guide you step by step.

Buy a book on computational science, look up libraries for physical computations. There is a multitude of things! Just name something specific and it will be more helpful. There is more free software relating to computational fluid dynamics that I know use C++. These other programs seem to use python more often than not.

Books for programming computation algorithms.
