Program to swap two numbers

This program is to swap/exchange two numbers by using a variable.

For example:

  Numbers to swap: 11 and 12  Let x= 11, y= 12    Swapping Logic:  t=x= 11  x =y =12  y =t =11    After swapping:  x= 12, y = 11  

Algorithm

STEP 1: START
STEP 2: DEFINE x, y, t
STEP 3: ENTER x, y
STEP 4: PRINT x, y
STEP 5: t = x
STEP 6: x= y
STEP 7: y= t
STEP 8: PRINT x, y
STEP 9: END

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();         System.out.println(“before swapping numbers: “+x +””+ y);         /*swapping */         t = x;         x = y;         y = t;         System.out.println(“After swapping: “+x +”” + y);         System.out.println( );      }    }  

Output:

Enter the value of X and Y  2  3  before swapping numbers: 2   3  After swapping: 3   2

C Program

  #include <stdio.h>  int main()  {    int x, y, t;// x and y are the swapping variables and t is another variable    printf(“Enter the value of X and Yn”);    scanf(“%d%d”, &x, &y);    printf(“before swapping numbers: %d   %dn”,x,y);  /*swapping*/    t = x;    x = y;    y = t;    printf(“After swapping: %d    %d”,x,y);    return 0;  }  

Output:

Enter the value of X and Y  29  39  before swapping numbers: 29   39  After swapping: 39  29

Python Program

  x = int(input(“Enter the value of x?”))  y = int(input(“Enter the value of y?”))  print(“before swapping numbers: %d   %dn” %(x,y))  #swapping#  temp = x  x = y  y = temp  print(“After swapping: %d   %dn”%(x,y))  

Output:

Enter the value of X?  87  Enter the value of Y?  43  before swapping numbers: 87  43  After swapping: 43  87

PHP Program

  <?php  echo “Enter the value of x”;  $x = readline();  echo “Enter the value of y”;  $y = readline();  echo “before swapping numbers: “;  echo $x;  echo ”    “;  echo $y;  echo “n”;  /*swapping*/  $temp = $x;  $x = $y;  $y = $temp;  echo “After swapping “;  echo $x;  echo ”    “;  echo $y;  ?>  

Output:

Enter the value of x  33  Enter the value of Y  22  before swapping numbers: 33  22  After swapping  22  33

C# Program

  using System;   public class Swap  {     public static void Main()      {      Console.WriteLine(“Enter the value of x and y”);      int x=Convert.ToInt32(Console.ReadLine());      int y = Convert.ToInt32(Console.ReadLine());      int temp;  Console.WriteLine(“before swapping numbers: “+x +””+ y);    /*swapping*/               temp = x;     x = y;     y = temp;  Console.WriteLine(“After swapping: “+x +”” + y);   }}  

Output:

Enter the value of x and y  65  54  before swapping numbers:  65  54  After swapping:  54  65
