What happens when I make a assignment to object which has copy constructor but no assignment operator?

Question

What happens when I make a assignment to object which has copy constructor but no assignment operator?
Will it call compiler's assignment operator, performing memberwise copy?

Answer 1

The copy constructor plays no role in assignment, the default assignment operator will be called that'll do a bit-wise copy of built-in type members and call assignment operator on object members of class type.
