Conditional and logical operators and expressions

The conditional operators are:
Table 1. Conditional operators
Operator Operation
== Equal
!= Not equal
> Greater than
< Less than
>= Greater than or equal
<= Less than or equal
The logical operators are:
Table 2. Logical operators
Operator Operation
&& AND
|| OR
! NOT
If you are entering && in an HTML or XML editor you might have to enter &amp;&amp;
In a conditional expression the terms are evaluated left to right. The order of precedence of the operators is the same order in which they are listed in the tables above. You can use parentheses to indicate the order in which you want expressions to be evaluated. Examples:
Expression:                  Evaluates to:

(4 > 3)                      true
!(4 > 3 )                    false
(4 > 3) && (8 > 10)          false
(4 > 3) || (8 > 10)          true
