continue
설명
continue 문은 루프(for, while, 또는 do...while)의 현재 반복의 나머지를 건너뛴다. 루프의 조건식을 체크하고 다른 일련의 반복을 진행한다.
예제 코드
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() {}

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

Example 2
아래 코드는 0에서 255까지의 코드 값을 PWMpin 에 쓰지만, 41에서 119 의 범위 값은 건너뛴다.
for (x = 0; x <= 255; x ++) {
if (x > 40 && x < 120) { // 값 중 건너뛸 것을 만듦
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() {
}

Inside the WHILE loop: i = 4, start

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() {
}
