Q&A: what if the assignment operator is implemented...

...as the following in the Instrument class?

class Instrument {
public:
  ...
  Instrument& operator=(const Instrument& rhs);
   ...
}

Instrument& Instrument::operator=(const Instrument& rhs) {
  delete [] description;
  description =   new char[strlen(rhs.description) + 1];
  strcpy(description, rhs.description);
  return *this;      
}

guess what happen when one tries the following

Instrument c("another bond");
c = c;
