Thread: Coding style

I would like to hear some thoughts about two different ways to code.
Would you put all variables int the beginning of the class and after that the functions, or do you mix them around?

Lets say you have a function that uses a list of integers. That list is only used by that function. Would you do

Code:

class A
{
   int a;
   int b;
   int list[20];
   ....
   void fun1();
   void fun2();
   void listFun();
   ...
};

or

Code:

class A
{
   int a;
   int b;   
   ....
   void fun1();
   void fun2();
   int list[20];
   void listFun();
   ...
};

Generally, I declare the public members of a class first, followed by protected members, followed by private members. Since member variables are usually private, they are thus declared towards the end.

The rationale is that everyone interested in the class would normally be interested in the public interface, but only those wanting to inherit from the class would also be interested in the protected interface, and only those needing to maintain the class would also be interested in the private implementation, hence this presents the parts of the class that the most people would be normally interested in first.
