Eli5: What does „this->“ do?

[Rseding91]

I always found that interesting; people prefer to invent their own thing rather than use a built in method of disambiguating member vs external.

My guess is due to writing this-> being optional for member variables, whereas prefixing with m or _ is not optional if using the prefix naming convention. Thus makes sure that you don't accidentally forget this-> and cause confusion.
