What are Increment/Decrement Operators?
The following are the auto increment, decrement operators in Perl.
|Operator ||Description |
|++ ||Autoincrement operator |
|-- ||Autodecrement operator |
The usage of auto increment operators are same as in C Language. In prefix decrement/increment first the value is increased or decreased then the new value is returned eg: "++$a", "--$a".
The vice versa of the above, is post decrement/increment operators. First the old value is returned then incremented or decremented to give the result. eg: "$a++", "$a--"
