Question

What is NULL? What happens when you perform arithmetic calculations on NULL
values?

Answer 1

Hi,

NULL or null pointer is a character with numeric value 0 and is generally used for an uninitialized, undefined, empty, meaningless value or byte which has all its bits set to 0.

It can also be thought of a literal that does not refer to any object.

If NULL values are involved in arithmetic operations or when we perform our arithmetic calculations on NULL values, the result will be numeric NULL values.

Hope it helps!
