signed vs unsigned integers
Signed integers and unsigned integers are two different ways of representing whole numbers in computer programming. Signed integers include both positive and negative numbers, ranging from the minimum representable negative value to the maximum representable positive value. They use one bit to represent the sign (positive or negative) and the remaining bits to represent the magnitude. On the other hand, unsigned integers represent only positive numbers or zero. They do not include negative numbers, so all bits are used to represent the magnitude of the number. In summary, signed integers allow the representation of both positive and negative numbers, while unsigned integers can only represent positive numbers and zero.
