Boucle do - while
La boucle do / while ("faire tant que" en anglais) fonctionne de la même façon que la boucle while, à la différence près que la condition est testée à la fin de la boucle, et par conséquent la boucle do sera toujours exécutée au moins une fois.
do
{
} while (condition);
void setup() {
Serial.begin(9600);
Serial.println("====== TEST START ======");
int i = 0;
do {
Serial.print("Inside the DO WHILE loop: i = ");
Serial.println(i);
i++;
} while (i < 5);
Serial.println("====== TEST END ========");
}
void loop() {
}
The result on Serial Monitor:
====== TEST START ======
Inside the DO WHILE loop: i = 0
Inside the DO WHILE loop: i = 1
Inside the DO WHILE loop: i = 2
Inside the DO WHILE loop: i = 3
Inside the DO WHILE loop: i = 4
====== TEST END ========
int x = 0;
do
{
delay(50);
x = readSensors();
} while (x < 100);
The while loop checks the condition before executing the block of code; conversely, the do while loop checks the condition after executing the block of code. Therefore, the do while loop will always be executed at least once, even if the condition is false at the beginning.
The do...while and while loop are the same, except for the case in which the condition is false at the beginning.
For example:
void setup() {
Serial.begin(9600);
Serial.println("====== TEST START ======");
int i = 10;
do {
Serial.print("Inside the DO WHILE loop: i = ");
Serial.println(i);
i++;
} while (i < 5);
Serial.println("====== TEST END ========");
}
void loop() {
}
====== TEST START ======
Inside the DO WHILE loop: i = 10
====== TEST END ========
void setup() {
Serial.begin(9600);
Serial.println("====== TEST START ======");
int i = 10;
while (i < 5) {
Serial.print("Inside the DO WHILE loop: i = ");
Serial.println(i);
i++;
}
Serial.println("====== TEST END ========");
}
void loop() {
}
====== TEST START ======
====== TEST END ========
※ Remarque:
There are three ways to escape the do while loop:
