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

This will not work in C++ because you are returning a reference to a temporary which will be destroyed once the function is over. You need to create a new person on the heap and then return a reference to that.
