You may do something like this

void swap(int *a, int *b){
*a=*a+*b;
*b=*a-*b;

*a=*a-*b;
}

Really Good

That would be what is known as the infamous Butterfly Switch.

ISO-C++ provides a swap function, so you don\'t need to write one yourself at all.

It is possible two swap 2 numbers without using arithmetic and bitwise operators?
If so how. Pl. send the code.

Hey! Can anyone tell me how one would swap strings in C/C without using a third variable and using pointers? i tried using memcpy() the results were not very satisfying.

@srikanth
This should work, you need to use "ref".

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleFunSwap
{
class Program
{
static void swap(ref int x, ref int y)
{
int c;
c = x;
x = y;
y = c;
}


static void Main(string[] args)
{
int a, b;
a = 300;
b = 200;
swap(ref a, ref b);
System.Console.WriteLine("{0}{1}", a, b);
System.Console.ReadLine();
}
}
}

thanx a lot.........
