value_1 = 3 > 2;
value_2 = 15 == 16;
cout << “Result of value 1 = ”<< value_1 << “\n”;
cout << “Result of value 2 = ”<< value_2 << “\n”;

- NOT (!)


Look this sample program.

number1 = (3 > 2) && (4 < 10);
number2 = !(15 == 15);
cout << “Result of number1 = ”<< number1 << “\n”;
cout << “Result of number2 = ”<< number2 << “\n”;
