Ones complement Operator

// 2’s Complement:
// Two’s complement is an operation on binary numbers. The 2’s complement of a number is equal to the complement of that number plus 1. 

// Example:

// Bitwise complement Operation of 2 (~ 0010 ): 1101

// Calculate 2’s complement of 3: 
// Binary form of 3 = 0011 
// 1’s Complement of 3 = 1100 
// Adding 1 to 1’s complement = 1100 +1
// 2’s complement of 3 = 1101  

// Note: 
// The bitwise Complement of 2 is same as  the binary representation of -3 

#include <stdio.h>

// Driver code
int main()
{
int n = 2;
printf("Bitwise complement of %d : %d",
		n, ~n);
return 0;
