c++ operator overloading memory question

Question

In c++ you can create new instances of a class on both the heap and stack. When overloading an operator are you able to instantiate on the stack in a way that makes sense?

Answer 1

You are correct that data on the stack is unusable when the function executes. However, it is perfectly okay to return copies of data on the stack (which is what you are doing). Just make sure you don't return pointers to data on the stack.
