Please follow the following rules when you post on the web
1. Don't beg for solution. No one will look into your problem
2. Don't claim it is Urgent. It is only urgent to you, not us. No one will drop what is on their hand and jump to help you.
3. Don't expect people to do your job. Show sufficent work you have done then ask for help when you get stuck on something. People will be more receptive to your question.

Solution 2

Try this:

C#

a = a+b  // a = 5, b=10     

b = a-b  // 15-10=5  

a = a-b  // 15-5=10
