++ (increment)

Availability

Flash Lite 1.0.

Usage

++expression

expression++

Operands

None.

Description

Operator (arithmetic); a pre-increment and post-increment unary operator that adds 1 to expression. The expression can be a variable, element in an array, or property of an object. The pre-increment form of the operator (++expression) adds 1 to expression and returns the result as a number. The post-increment form of the operator (expression++) adds 1 to expression and returns the initial value of expression (the value before the addition).

Example

The following example uses ++ as a post-increment operator to make a while loop run five times:

i = 0;
while (i++ < 5){
    trace("this is execution " + i);
}

The following example uses ++ as a pre-increment operator:

a = "";
i = 0;
while (i < 10) {
    a = a add (++i) add ",";
}
trace(a);        // output: 1,2,3,4,5,6,7,8,9,10,

This script shows the following result in the Output panel:

1,2,3,4,5,6,7,8,9,10,

The following example uses ++ as a post-increment operator:

a = "";
i = 0;
while (i < 10) {
    a = a add (i++) add ",";
}
trace(a);        // output: 0,1,2,3,4,5,6,7,8,9,

This script shows the following result in the Output panel:

0,1,2,3,4,5,6,7,8,9,
