"lazy erase with vector"

[Tomhet]

is it possible to auto erase a pointer from a vector container?
a stuff what's like swap...

#include<vector>

int main(){
	std::vector<int*>ptrs;

	int*ptr=new int[20];
		ptrs.push_back(ptr);
	
	//size() = 1
	
	autoremove(ptr,ptrs);//that thing
	
	delete[]ptr;
	
	//size() = 0
	
	
	return 0;
};

Huh? What does it mean to "auto erase"?

There is no way for the vector to know that pointers it holds have had their pointed-to memory deallocated, if that is what you are asking.
