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
Send
====== 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
Send
====== 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
Send
====== 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 ========
