Array an Array: : operator ^ (Array & amp; C2)
This returns a temporary object, there will be a problem

CodePudding user response:

The

reference 1/f, Simple, Soft reply:

Array Array: : operator ^ (Array & amp; C2)
This returns a temporary object, there will be a problem of

Then how to solve?

CodePudding user response:

Add a copy constructor, and the operator=

CodePudding user response:

Returns a temporary object, return a temporary object reference only has a problem,,,,,,,
