Program in C

Here is the source code of the C Program to swap two numbers using bitwise operators.

Code:

#include <stdio.h>
int main()
{
    int num1, num2;
    /* Get the two numbers input */
    printf("Enter the two Numbers:");
    scanf("%d %d", &num1, &num2);
    /*Swaping two numbers using bitwise XOR operators.*/
    num1 = num1 ^ num2; /* ^(XOR operators) */
    num2 = num1 ^ num2;
    num1 = num1 ^ num2;
    printf("After Swapping two Numbers are:\n");
    printf("Number1=%d\nNumber2=%d\n", num1, num2);
    return 0;
}

Code:

import java.util.Scanner;
public class SwapTwoNumber {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        /* Get the two numbers input */
        System.out.print("Enter the Two Numbers:");
        int num1 = sc.nextInt();
        int num2 = sc.nextInt();
        /* Swaping two numbers using bitwise XOR operators. */
        num1 = num1 ^ num2; /* ^(XOR operators) */
        num2 = num1 ^ num2;
        num1 = num1 ^ num2;
        System.out.print("After Swapping two Numbers are:\nNumber1= " + num1 + "\nNumber2= " + num2);
        sc.close();
    }
}

Input/Output:

Enter the Two Numbers:51 99

After Swapping two Numbers are:

Number1= 99

Number2= 51
