Write a program to swap two numbers
Program:
CODE IN C LANGUAGE:
#include<stdio.h>
#include<conio.h>
void main()
{
int
m=4, n=15;
clrscr();
n=m-n+(m=n);
printf("m=%d,
n=%d",m,n);
getch();
}

CODE IN JAVA(in
netbeans):
package swap;
import java.util.*;
public class Swap
{
public static void main(String[] args)
{
Scanner in=new Scanner(System.in); System.out.println("Enter value
for a: ");
int a=in.nextInt();
System.out.println("Enter value for b: ");
int b=in.nextInt(); System.out.println("Values before swap-
a="+a+", b="+b);
b=a+b-(a=b);
System.out.println("Values after swap- a="+a+",
b="+b);
}
}
CODE IN JAVASCRIPT:
<html>
<body>
<script>
Var x=10;
Var y=5;
y=x-y+(x=y);
document.write(“value
of x is “+x+” and value of y is “+y);
</script>
</body>
</html>
