\\

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.

  // statement(s);

  // #statement(s)

Description

While loops will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false. Something inside the loop must change the tested variable, or the while loop will never exit.

Syntax

while(expression){

#statement(s)

}

Parameters

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

Example

  // do something repetitive 200 times

While statements

Loops continuously until the expression inside () are not true. Useful for creating your own loops, but make sure to keep track of some variable you can use to stop the while loop if that is your intent.

Example

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