Subtract two numbers using bitwise operators

Here given code implementation process.

// C Program 
// Subtract two numbers using bitwise operators
#include <stdio.h>

// Perform subtract of two numbers
void subtractNum(int a, int b)
{
	// Display given number
	printf("\n Number a : %d", a);
	printf("\n Number b : %d", b);
	printf("\n Subtract ((%d)-(%d))", a, b);
	int temp = 0;
	// Subtract of two numbers
	while (b != 0)
	{
		temp = ((~a) & b) << 1;
		a = a ^ b;
		b = temp;
	}
	// Display calculated result
	printf("\n Output :  %d\n", a);
}

	subtractNum(12, -31);
	subtractNum(3, 4);
	subtractNum(-1, -4);
	subtractNum(12, 4);

Output

 Number a : 12
