while
¶
Syntax¶
while (expression) {
// block of code
}
Description¶
while
loops will repeat the statements inside their associated
block of code until the expression inside the parentheses becomes
false. Something must change the tested
expressions’ value, 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.
Example¶
var = 0;
while(var < 200) {
// do something repetitive 200 times
var++;
}
