c++ - What default constructors do we need to provide in each class? -


this question has answer here:

i assumed compiler automatically generate copy constructors , copy operators in c++ if 1 not specified. case move constructor/move operator?

i reading articles state move semantics break if there custom destructor declared in class.

when make sense write move constructor/move operator?
