In simple terms, two's complement is a way to store negative numbers in computer memory. Whereas positive numbers are stored as a normal binary number.

Let's consider this example,

The computer uses the binary number system to represent any number.

x = 5;

This is represented as 0101.

x = -5;

When the computer encounters the - sign, it computes it'sits two's complement and stores it.

That is, 5 = 0101 and its two's complement is 1011.

The important rules the computer uses to process numbers are,

  1. If the first bit is 1 then it must be a negative number.
  2. If all the bits except first bit are 0 then it is a positive number, because there is no -0 in number system (1000 is not -0 instead it is positive 8).
  3. If all the bits are 0 then it is 0.
  4. Else it is a positive number.
