explicit

• See, the developers of C++ realized that sometimes, automatic type conversions can get you into trouble.

• explicit Stonewt ( double lbs ); // no implicit type conversions.

  • Stonewt myCat; // ok
  • myCat = 19.6; // Not ok
  • myCat = Stonewt(19.6); // ok (explicit conv)
  • myCat = (Stonewt) 19.6; // ok (old fashioned)
