Message: [QUOTE="tommy.hinks, post: 3499847"] I am wondering if anyone knows how compilers auto-generate copy constructors for PODs. Let me explain what I mean with an example: struct A { int u; int v; }; If I were to write the copy constructor for the POD myself, I would write it like this: A::A(const A rhs) : u(rhs.u), v(rhs.v) {} the main point being that the member variables are initialized upon creation, and not created and then assigned a value, like this: A::A(const A rhs) { u = rhs.u; v = rhs.v; } Or perhaps some other form of bitwise (shallow) copying is done by the compiler for auto-generated PODs? Any thoughs on this? Thanks, T [/QUOTE]
