Let’s say we have four files: a.h, a.cpp, b1.h, and b2.h. And, we need to include b1.h and b2.h in either a.h or a.cpp. Where should I include b1 and b2? Let’s say only a.cpp needs b1 and b2.

If it’s not needed for the header file then include it in the cpp.
This reduces compilation time and helps to understand the dependencies between the modules.
