!=
설명
왼쪽 변수와 연산자 오른쪽 변수를 비교. 두 피연산자가 같지 않으면 true 반환.
Please note that you may compare variables of different data types, but that could generate unpredictable results, it is therefore recommended to compare variables of the same data type including the signed/unsigned type.
문법
x != y; // x와 y가 같으면 거짓, x와 y가 같지 않으면 참
매개변수
- x: 변수. 허용되는 자료형: int, float, double, byte, short, long
- y: 변수 또는 상수. 허용되는 자료형: int, float, double, byte, short, long
예제 코드
void setup() {
Serial.begin(9600);
int x = 1;
int y = 2;
if (x != y) // x 가 y 와 같지 않으면
Serial.println("x is NOT equal to y");
else
Serial.println("x is equal to y");
}
void loop() {
}
시리얼 모니터에 결과:
