Question

What will the following 2 Arduino code print on the serial monitor?  
int x =1 ;
void setup() {       
Serial.begin(9600);  
}   
void loop() {       
Serial.println(x);  
x = x+1;
}       

And

int x =1 ;
void setup() {       
Serial.begin(9600);  
}   
void loop() {   
if (x < 10) {   
Serial.println(x);  
x = x+1;
}
else {  
Serial.println(x);  
}
}

Answer 1

the first program will print

number from 1 than add 1 to it and than print 2

and keep on adding 1 to prevoius number and printing .

i have taken two snapshots of serial monitor.

actually its a infinte loop.

your second program will keep on printing 10 on serial monitor again and again
