These operations raise (increase) or reduce (decrease) the value of a vector (decrease). Because just one operator is employed, they are frequently referred to as uniform operators. To raise or reduce a value by a factor of one, operators for increasing and decreasing are used. Pre-incrementing operator The new $x value is returned when the value is added to it. See the table below for a better understanding:

• Operator Name Description
• ++$x Pre-increment Increments $x by one, then returns $x
• $x++ Post-increment Returns $x, then increments $x by one
• --$x Pre-decrement Decrements $x by one, then returns $x
• $x-- Post-decrement Returns $x, then decrements $x by one
