C++ Casting a pointer in a new?

I have this line of code which I cannot make sense of.

ClassA *pointer= new( ( char* )BASE_ADDRESS)ClassA ;

What does this cast
( ( char* )BASE_ADDRESS)
even mean?

is some memory location.


This is called placement new. It constructs an object of type ClassA and puts it in the memory location specified by BASE_ADDRESS.
