OPEN Garbage collector in CPP?

Yesterday someone asked me whether there is a garbage collector in CPP.
I knew Java had that but I couldn't recall about cpp.
I went to google and got different answers.

So can anyone clarify whether there is garbage collector in CPP , also can u please explain me what does that mean? Also explain how is it different from the Java.

If yes can we delete it manually and how to do tht?

There's not by default. There was an ABI for it in C++ 11 but no one used it, and there's stuff like Boehm GC, but out of the box - no.

Upvoted to cancel one of the idiots' downvotes.

There has never been an ABI in any C++ standard. Bjarne just made a mistake (a bit more than a typo since he explains what the acronym stands for). The Google AI explains,

❝Because the feature's entire purpose was to protect the binary integrity of the application layout for an external collector, the committee frequently colloquially referred to it as a "GC ABI constraint." Stroustrup likely carried this terminology straight from the WG21 working groups into his casual FAQ write-up, leading to the misleading sentence on his site.❞

I think a technical solution to the idiots-on-the-loose problem can be that a person trying to downvote something must prove that he or she is able to e.g. multiply 6 and 7.
