! not

• Note the strange logic in some of my examples in short.cpp. If ( exp ) ; else { };

• This is hard to read.

• It often is easier to reverse the expression by using the not operator.

• if ( x < 12 ) ; else cout << “hi!”<< endl;

• if ( ! (x < 12) ) cout << “hi!” << endl;

• if ( x >= 12 ) cout << “hi!” << endl;

• All three identical results.
