Languages Focus: Logical Operators

Logical operators perform conditional and, or, and not operations. Some languages support both binary logical operators that link two and unary logical operators negate (make opposite) the truth value of its argument. Finally, some languages short circuit logic. For example, with this or that, if this is an expression returning true, then that is never executed.

C# Logical Operators

Same as C++ and Java. C# logical operators:

& and, as in this and that No Short Circuit
&& and, as in this and that short circuits
| or, as in this or that No Short Circuit
|| or, as in this or that short circuits
! Not, as in Not This
^ either or, as in this or that but not both

Syntax Example:
//Given expressions a, b, c, and d:
if !((a && b) && (c || d)) 
{
  //Do something.
}
