while

Last revision 05/16/2024

Description

A 

while
loop will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false. Something must change the tested variable, or the while loop will never exit. This could be in your code, such as an incremented variable, or an external condition, such as testing a sensor.

Syntax

1while (condition) {
2      // statement(s)
3    }

Parameters

condition
: a boolean expression that evaluates to 
true
or 
false
.

Example Code

1var = 0;
2    while (var < 200) {
3      // do something repetitive 200 times
4      var++;
5    }
