Logical Operator are those operator which are used to combine two or more than two condition to form a single larger compound condition,possible logical operator are-:
Logical AND- &&
Logical OR- | |
Logical NOT- !
The precedence of logical operator are as follow-:
[ ! ]- I
[ && ]- II
[ | | ]- III
Truth Table-:
Logical AND and Logical OR are also known as Short ciruit operator.
Example-:
[(a>b)&&(a<c)]
The above expression has two condition join by using Logical AND. So,if the first condition is TRUE[1], then also compiler will check the second condition but if the first condition is FALSE[0],then compiler will not check the second condition.
[(a<b)| |(a>b)]
The above expression has two condition join by using Logical OR. So,if the first condition is TRUE[1], then also compiler will not check the second condition but if the first condition is FALSE[0],then compiler will check the second condition.
The above operational behaviour shows the concept of short-circuiting.
Logical AND and Logical OR are binary in nature while Logical NOT is an Unary operator.
