निम्नलिखित Arduino कोड का आउटपुट क्या होगा?
What will be the output of the following Arduino code?
#define X 10;
void setup(){
X=0;
Serial.begin(9600);
Serial.print(X);
}
void loop(){
//Do nothing…
}
A)
B)
C)
D)
Explanation:
The code tries to change the value of X, which is defined as a constant using #define. Constants cannot be reassigned, so the line X = 0; causes a compilation error.
Correct Answer:
(D) Error.
