What is bitwise complement operator ?

The bitwise complement (~) operator works with bits and used for inverts the bits of a operand or a variable. It is a unary operator so it works with only one operand. The inversion of bits means, it convert the bit value from 0 (zero) to 1 (one) and from 1 (one) to 0 (zero), for example:

X = 1010110

~X = 0101001

The bitwise complement operator is also called one’s complement operator. It is used at the beginning of an operand.

Sy:

~ operand;

Ex:

z = ~x;
