Question

On the Arduino Uno, data type int stores values that range from:

a) 0 to 65 535
b) 0 to 32 768
c) -65 536 to 65 535
d) -32 768 to 32 767

Answer 1

On the Arduino Uno, the int data type can store integer values ranging from -32,768 to 32,767, which is typical for 16-bit signed integers.

Step-by-step explanation:

On the Arduino Uno, the data type int stores values that range from -32,768 to 32,767. This is because an int on the Arduino is a 16-bit signed number, which means it can represent 215 negative numbers and 215 - 1 positive numbers, including zero. This range is essential for selecting the correct data type for variables that will store integers in the sketches that you write for the Arduino, as choosing the wrong data type may result in overflow errors or waste of memory.
