What is the difference between static and dynamic (shared) libraries in C++?

Hello everyone! I recently started learning C++ and am trying to understand libraries. I look at projects on GitHub and see that some link .lib files, others .dll (or .so on Linux). As far as I understand, there are two types of libraries: static and dynamic (shared). Can someone explain in simple terms what the difference is? I have a small project: I wrote a class for working with matrices (multiplication, transposition, etc.). Now I want to make it into a library to use in different programs. But I don't understand which type to choose. What happens if I use a static library? And if I use a dynamic one? How will this affect the executable file size, performance, and ease of updating? Here is an example of the code I want to turn into a library: ```cpp // matrix.h #pragma onc ```
