Here is the logic from my side.
a = b - a;
b = b - a;
a = a + b;
Console.WriteLine(a + ", " + b);

to verify use calculator with minus sign
i think its a very good logic and if in ur application or coding this has been failed then can u tell us in which language and what cade u r using????

Hey,
Its working for me.. Here is the complete code.
Copy this in Main function
---------------------------
Console.WriteLine("Enter first number :");
int a = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter second number :");
int b = Convert.ToInt32(Console.ReadLine());
SwapNumbers(a, b);
Console.ReadLine();
Copy this outside main
----------------------
private static void SwapNumbers(int a, int b)
{
Console.WriteLine("After Swapping: ");
a = b - a;
b = b - a;
a = a + b;
Console.WriteLine(a + ", " + b);
}

b=b-a
a=b+a
b=a-b
EX--Suppose a=18 b=65
b=65-18=47
a=47+18=65
b=65-47=18
UR Example--Suppose a=5 b=10
b=10-5=5
a=5+5=10
b=10-5=5
Reply if u got it.

ki karthe check mine reply its even working for numbers a=13, b=7
b=7-13=-6
a=-6+13=7
b=7-(-6)=13

Hi,
The problem is when you minus the one number.
e.g. a = 7, b = 5.
a = b - a, then you will get a negative number.
So, just check which is the larger number and use that number to subtract and the solution will work :]....
