continue
Descripción
La sentencia continue se salta el resto de la iteración actual de un bucle (do, for, o while). Después continúa la comprobación de la expresión condicional del bucle, y con cualquiera de las iteraciones posteriores.A diferencia de break, el bucle no se abandona, sino que se seguirá ejecutando mientras la condición se cumpla.
Ejemplo
Example with For Loop
Example 1
The following code exits the for loop when the i greater than 3
void setup() {
Serial.begin(9600);
Serial.println("====== TEST START ======");
for (int i = 1; i < 5; i++) {
Serial.print("Inside the FOR loop: i = ");
Serial.print(i);
Serial.println(", start");
if(i > 2)
continue;
Serial.print("Inside the FOR loop: i = ");
Serial.print(i);
Serial.println(", end");
}
Serial.println("====== TEST END ========");
}
void loop() {}
The result on Serial Monitor:
COM6
====== TEST START ======
Inside the FOR loop: i = 1, start
Inside the FOR loop: i = 1, end
Inside the FOR loop: i = 2, start
Inside the FOR loop: i = 2, end
Inside the FOR loop: i = 3, start
Inside the FOR loop: i = 4, start
====== TEST END ========

Example 2
The following code writes the value of 0 to 255 to the PWMpin, but skips the values in the range of 41 to 119.
for (x = 0; x < 255; x ++) {
if (x > 40 && x < 120) { // crea un salto de valores
continue;
}
analogWrite(PWMpin, x);
delay(50);
}
Example with While Loop
The following code exits the while loop when the i greater than 3
void setup() {
Serial.begin(9600);
Serial.println("====== TEST START ======");
int i = 0;
while (i < 5) {
i++; // increase i by 1
Serial.print("Inside the WHILE loop: i = ");
Serial.print(i);
Serial.println(", start");
if(i > 2)
continue;
Serial.print("Inside the WHILE loop: i = ");
Serial.print(i);
Serial.println(", end");
}
Serial.println("====== TEST END ========");
}
void loop() {
}
The result on Serial Monitor:
COM6
====== TEST START ======
Inside the WHILE loop: i = 1, start
Inside the WHILE loop: i = 1, end
Inside the WHILE loop: i = 2, start
Inside the WHILE loop: i = 2, end
Inside the WHILE loop: i = 3, start
Inside the WHILE loop: i = 4, start
====== TEST END ========

Example with Do While Loop
The following code exits the while loop when the i greater than 3
void setup() {
Serial.begin(9600);
Serial.println("====== TEST START ======");
int i = 0;
do {
i++; // increase i by 1
Serial.print("Inside the DO WHILE loop: i = ");
Serial.print(i);
Serial.println(", start");
if(i > 2)
continue;
Serial.print("Inside the WHILE loop: i = ");
Serial.print(i);
Serial.println(", end");
} while (i < 5);
Serial.println("====== TEST END ========");
}
void loop() {
}
The result on Serial Monitor:
COM6
====== TEST START ======
Inside the DO WHILE loop: i = 1, start
Inside the DO WHILE loop: i = 1, end
Inside the DO WHILE loop: i = 2, start
Inside the DO WHILE loop: i = 2, end
Inside the DO WHILE loop: i = 3, start
Inside the DO WHILE loop: i = 4, start
====== TEST END ========
