operator++(); 和有什么区别？ 调用和 ++(*this)？

Question

I'm calling operator++() in my class constructor, and it is recommended to use operator++(); instead of ++(*this). What is the difference between the two?

Answer 1

There is essentially no difference. ++(*this) is rewritten to an invocation of operator++() .

It is possible that in obscure cases the overload resolution could be different, but you probably want to avoid the scenarios where that would be the case anyway.

I would use ++(*this) .
