  cout << "The BMI for " << bmi1.getName() << " is "
    << bmi1.getBMI() << " " << bmi1.getStatus() << endl;

  BMI bmi2("Peter King", 215, 70);
  cout << "The BMI for " << bmi2.getName() << " is "
    << bmi2.getBMI() << " " + bmi2.getStatus() << endl;

  system("pause");
  return 0;
}


Here is the output:

The BMI for John Doe is 20.8051 normal weight
The BMI for Peter King is -1.#QNAN gravely overweight
Press any key to continue . . .


Not sure why the second is displaying the reference of the memory..any ideas?
