Signed versus Unsigned Integers?

Question

Am I correct to say the difference between a signed and unsigned integer is:1. Unsigned can hold a larger positive value, and no negative value.2. Unsigned uses the leading bit as a part of the value, while the signed version uses the left-most-bit to identify if the number is positive or negative.3. signed integers can hold both positive and negative numbers.Any other differences?

Answer 1

Signed Integers use one bit (the MSB) to represent the sign and can represent both positive and negative numbers, typically using two’s complement representation.

Unsigned integers use all bits to represent magnitude and can only represent non-negative values, allowing a larger maximum value.

They differ in value ranges, overflow behavior, comparisons, and bit-shift semantics.
