Vector push_back and destructor function(?): push_back(~Dword(0))

Here is the code:

std::vector<Dword> s;

s.push_back(~Dword(0));

What is ~Dword? How does it work?

Dword here is a numeric type (probably a type alias for DWORD; an unsigned 32 bit integer). When you write Dword(0), you make a Dword with the value 0, then ~Dword(0) does a bitwise negation of it.

So ~Dword(0) is read as bitwise-negate a Dword of value 0
