Control Structures while

while loops

Description

while loops 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

while(expression){
  // statement(s)
}

Parameters

expression - a (boolean) C statement that evaluates to true or false

Example

var = 0;
while(var < 200){
  // do something repetitive 200 times
  var++;
}
