Conditional Statements

if/else

void setup() { Serial.begin(9600); //begin using serial communication }
void loop() {int l = 10; //declare a variable called l and give it the value 10int w = 6; //declare a variable called w and give it the value 6int area = l * w; //declare a variable called area and equate it to l times w
if(area>50) { Serial.println("The area of the rectangle is big!"); //prints the text if the area is bigger than 50 }else { Serial.println("The area of the rectangle is small"); //prints the text if the area is not bigger than 50 }}
