Can anyone provide some link which has some details to unpack a creackme (Packed using UPX I think). It will be very helpful if it can  explain how the unpack of UPX works (instead of just giving steps to unpack it). I am more interested to know how it works.

A) Crackme.
B) Where's the solution for MY crackme?

i am asking about the same crackme :D in this thread...

Yes that is a good approach and it is followed almost everywhere (“as far as I know”)...

This is my understanding from your answer:
1.   you only meant non-static methods in the .h file. 
2.   Static method signature does not required if static method definition is placed before caller method.

But I faced lot of question when I don’t put the declaration of a static method in case 2. I could not find a book or a link which says that this is not necessary (which I can send to a person to justify my point)

In the scenario 1 I must declare method on the top, but should I declare it in the scenario 2 also?

Scenario 1:
=========
Static void local_method(int param);

Void caller()
{
   local_method(1);
}

Static void local_method(int param)
{
   // doing something
} 


Scenario 2:

/* I have define this method before caller, should I still declare its method signature above.
What is the benefit I will get if I declare it  on the top */
Static void local_method(int param)
{
   // doing something
} 

Void caller()
{
   local_method(1);
}
