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() {}

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() { }

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() { }
