Most of the time we don't have to worry about defining copy/move constructors and assignment operators -- the compiler happily generates them for us. Sometimes, however, we must do the dirty work ourselves and code them up manually, often together with the destructor. By hand crafting the assignment operators, we sometimes gain extra efficiency (e.g. std::vector re-using the memory in copy-assignment) but most of the time the code just ends up looking like a copy/paste job of destructor and copy/move constructor.
