  2. #include<stdlib.h>
  3. int main()
  4. {
  5. int a=10, b=20;
  6. printf(“Before swap a=%d b=%d”,a,b);
  7. a=a*b;//a=200 (10*20)
  8. b=a/b;//b=10 (200/20)

How do you swap two numbers in a string?

How can I swap two numbers without using arithmetic operators?

How to swap two numbers without using a third variable

  1. Using arithmetic operators. Swapping two variables without using a third variable. …
  2. 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.

  1. using System;
  2. public class SwapExample.
  3. {
  4. public static void Main(string[] args)
  5. {
  6. int a=5, b=10;
  7. Console.WriteLine(“Before swap a= “+a+” b= “+b);
  8. 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:

  1. Reverse a string using the strrev() function.
  2. Reverse a string without using the library function.
  3. Reverse a string using the recursion function.

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] .
