Swapping Two Numbers using a 3rd variable

C Program

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int x,y,temp;
    printf("Enter first Digit:");
    scanf("%d",&x);
    printf("Enter Second Digit:");
    scanf("%d",&y);
    printf("Before swapping x=%d, y=%d",x,y);
    temp=x;
    x=y;
    y=temp;
    printf("\nAfter  swapping x=%d, y=%d",x,y);
    return 0;
}

Java Program

import java.util.Scanner;

public class Swap {

	public static void main(String[] args) 
	{
		Scanner S = new Scanner(System.in);
		int x,y,temp;
	    System.out.print("Enter first Digit:");
	    x = S.nextInt();
	    System.out.print("Second Digit:");
	    y = S.nextInt();
	    System.out.print("Before swapping x = " + x + " y = " + y);
	    temp=x;
        x=y;
        y=temp;
	    System.out.print("\nAfter  swapping x = " + x + " y = " + y);
	   
	}

}

Python Program

x = int(input("Enter a number: "))
y = int(input("Enter another number: "))
print("Before swapping :")
print("x is " + str(x) + " Y is " + str(y))
z=x
x=y
y=z
print("After swapping :")
print("x is " + str(x) + " Y is " + str(y))
