## How do you swap 2 values?

Let’s see another example to swap two numbers using * and /.

- #include<stdio.h>
- #include<stdlib.h>
- int main()
- {
- int a=10, b=20;
- printf(“Before swap a=%d b=%d”,a,b);
- a=a*b;//a=200 (10*20)
- b=a/b;//b=10 (200/20)

## How do you swap two numbers in a string?

Java Program

- import java.util.*;
- class Swap_With {
- public static void main(String[] args) {
- int x, y, t;// x and y are to swap.
- Scanner sc = new Scanner(System.in);
- System.out.println(“Enter the value of X and Y”);
- x = sc.nextInt();
- y = sc.nextInt();

## How do you use an algorithm to swap two numbers?

Algorithm

- STEP 1: START.
- STEP 2: ENTER x, y.
- STEP 3: PRINT x, y.
- STEP 4: x = x + y.
- STEP 5: y= x – y.
- STEP 6: x =x – y.
- STEP 7: PRINT x, y.
- STEP 8: END.

## How do you swap numbers in JavaScript?

4 Ways to Swap Variables in JavaScript

- Destructuring assignment. Destructuring assignment (a feature of ES2015) lets you extract items of an array into variables. …
- Temporary variable. Swapping variables using a temporary variable is classic. …
- Addition and difference. …
- Bitwise XOR operator. …
- Conclusion.

## How can I swap two numbers without using arithmetic operators?

How to swap two numbers without using a third variable

- Using arithmetic operators. Swapping two variables without using a third variable. …
- Using Bitwise XOR. The result of the bitwise XOR operator is 1 if the corresponding bits of two operands are opposite.

## How do you swap variables?

The bitwise XOR operator can be used to swap two variables. The XOR of two numbers x and y returns a number that has all the bits as 1 wherever bits of x and y differ. For example, XOR of 10 (In Binary 1010) and 5 (In Binary 0101) is 1111 and XOR of 7 (0111) and 5 (0101) is (0010).

## How can I swap two strings in C# without using third variable?

Let’s see a simple C# example to swap two numbers without using third variable.

- using System;
- public class SwapExample.
- {
- public static void Main(string[] args)
- {
- int a=5, b=10;
- Console.WriteLine(“Before swap a= “+a+” b= “+b);
- a=a*b; //a=50 (5*10)

## How would you swap 2 strings without a temporary variable?

Method: In order to swap two string variables without using any temporary or third variable, the idea is to use string concatenation and substring() methods to perform this operation.

## How do you reverse a string?

Following are the various ways to find the reverse of a string in the C programming language:

- Reverse a string using the strrev() function.
- Reverse a string without using the library function.
- Reverse a string using the recursion function.
- Reverse a string using for loop.
- Reverse a string using while loop.

## How do I swap numbers in a flowchart?

Algorithm and Flowchart to Swap Two Integer Numbers

- Declare a variable a,b and c as integer; Read two numbers a and b; c=a; a=b; b=a; Print a and b.
- STEP 1: START STEP 2: ENTER A, B STEP 3: PRINT A, B STEP 4: A = A + B STEP 5: B= A – B STEP 6: A =A – B STEP 7: PRINT A, B STEP 8: END.

## How do you swap two numbers in Python?

Method 2: By using comma operator

- P = int( input(“Please enter value for P: “))
- Q = int( input(“Please enter value for Q: “))
- # To Swap the values of two variables.
- P, Q = Q, P.
- print (“The Value of P after swapping: “, P)
- print (“The Value of Q after swapping: “, Q)

## Which algorithm is correct for swapping of two numbers in C programming?

Swap Two Numbers Using Bitwise XOR.

## How do you write a swap function in JavaScript?

Here, a new es6 feature, called destructuring assignment [a, b] = [b, a] , is used to swap the value of two variables. If [a, b] = [1, 2, 3] , the value of a will be 1 and value of b will be 2. First a temporary array [b, a] is created. Here the value of [b, a] will be [2, 4] .

## How can I swap two variables without using third variable in Java?

Swap two numbers without using third variable in java

- class demo {
- public static void main(string arg[]) {
- System.out.println(“Before swapping”);
- int x = 10;
- int y = 20;
- System.out.println(“value of x:” + x);
- System.out.println(“value of y:” + y);
- system.out.println(“After swapping”);

## How do you swap values in Java?

Java Program to Swap two Variables

- Assign x to a temp variable : temp = x.
