do...while

[Control Structure]

Description

The do…​while loop works in the same manner as the while loop, with the exception that the condition is tested at the end of the loop, so the do loop will always run at least once.

Syntax

do {
  // statement block
} while (condition);

Parameters

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

Example Code

// initialize x and i with a value of 0
int x = 0;
int i = 0;

do {
  delay(50);          // wait for sensors to stabilize
  x = readSensors();  // check the sensors
  i++;                // increase i by 1
} while (i < 100);    // repeat 100 times
