Add two numbers using bitwise operators in scala
Scala program for Add two numbers using bitwise operators. Here problem description and explanation.
// Scala program for
// Add two numbers using of bitwise operators
class NumberAddition()
{
// Add two numbers
def addition(x: Int, y: Int): Unit = {
var a = x;
var b = y;
// Display given numbers
print("\n [(" + a + ") + (" + b + ")] ");
// Auxiliary variable which are store the carry bit result
var carry: Int = 0;
// Executing loop, until b value is not zero
while (b != 0)
{
// Get carry bits of a & b
carry = a & b;
// Sum of bits of a ^ b
a = a ^ b;
// Shift the carry bit by one bit in left side
b = carry << 1;
}
// Display add result
print(" : " + a);
}
}
object Main
{
def main(args: Array[String]): Unit = {
var task: NumberAddition = new NumberAddition();
// Test Case
task.addition(8, -2);
task.addition(5, 3);
task.addition(-3, -5);
}
}
Output
[(8) + (-2)] : 6
[(5) + (3)] : 8
[(-3) + (-5)] : -8
