Safe in C# not in C++, simple return of pointer / reference

Question

C++ code:

person* NewPerson(void)
{
  person p;
  /* ... */
  return &p; //return pointer to person.
}

C# code:

person          


        

Answer 1

Yes, you got it right.

However, in C++ you would really do like this

person NewPerson()
{
  person p;
  /* ... */
  return p; //return person.
}

and be pretty sure that in a call

person x = NewPerson();

the compiler will optimize out the copying of the return value.
