Description

Used to increment or decrement a variable by one.

Syntax

result = --variable
result = variable++
result = variable--

Syntax 2

++variable
--variable
variable++
variable--

The syntax of the ++ and -- operators has these parts:

Part	Description
result	Any variable.
variable	Any variable.

Remarks

The increment and decrement operators are used as a shortcut to modify the value stored in a variable. The value of an expression containing one of these operators depends on whether the operator comes before or after the variable:

var j, k
k = 2
j = ++k

j is assigned the value 3, as the increment occurs before the expression is evaluated. Contrast the following example:

var j, k
k = 2
j = k++

Here, j is assigned the value 2, as the increment occurs after the expression is evaluated.
