Copy and paste the following Perl program in file and execute this program. An operator is a character that represents an action, for example + is an arithmetic operator that represents addition. Try the following example to understand all the logical operators available in Perl. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. What is this Perl statement all about 'Hello World' is a simple double-quoted string.

Regexes are not involved for the last one.

If a condition is true then Logical NOT operator will make false. It's generally used to apply a regular expression to a string for instance, to test if a string matches a pattern: More specifically, it’s used to bind a m//, s///, or y/// ( tr///) operator to a scalar. You can take, for example, () which is an operator used for multiplying the values of two variables. Use to reverses the logical state of its operand. Here 4 and 5 are called operands and + is called operator. Operators in Perl Operators are symbols which tell the compiler to perform certain operations on variables. If any of the two operands are non zero then then condition becomes true.Ĭ-style Logical OR operator copies a bit if it exists in eather operand.Ĭalled Logical NOT Operator.

If both the operands are true then then condition becomes true.Ĭ-style Logical AND operator copies a bit to the result if it exists in both operands.Ĭalled Logical OR Operator. Assume variable $a holds true and variable $b holds false then − Sr.No.Ĭalled Logical AND operator. There are following logical operators supported by Perl language.
