The operator can have multiple levels of arity. The 0-ary operator takes no arguments as input; a 1-ary or unary operator takes one object as input, and a 2-ary or binary operator takes two objects and input. In
This operators also known as Bitwise negation and one’s compliment operator in C language, it is a Unary operator in C and C++, it converts (inverse) individual bits from 0 to 1 and 1 to 0.For example: there is a variable x with value 0xAA (in binary 1010 1010), ~x will be ...

logical state of its operand, bitwise not flips all the bits of its operand, changing each 0 to 1 and each 1 to 0. it's used for low-level bit manipulation, often in scenarios like complementing binary numbers or inverting bitmasks for bitwise operations. what is the address of operator...
