What does the explicit keyword do in C++, and when should it be used?

I’ve seen the explicit keyword used in C++ class constructors, but I’m not entirely sure what it means or why it’s needed. From what I understand, it prevents implicit conversions, but could someone explain how explicit works in C++, maybe with a simple example? Also, in what situations is using the C++ explicit keyword strongly recommended or considered best practice?
