    Typically, I'll do public, protected, and private, with constructors, functions and data members within these groups.

    It's up to each person's personal preference, but I find that this order makes it easier when using header files as documentation.
    I copied it from the last program in which I passed a parameter, which would have been pre-1989 I guess. - esbo

    It's individual preference. I do public, protected, constructors, destructors, operators, member functions, variables.

    Outside of your DOS world, your header file is meaningless.

    I think it's a good idea to put the interface first so that other developers can quickly find what they need. In other words, what Elysia wrote.

    I usually put all my member variables at the top, then public, protected & private functions; but if you have a good IDE it probably doesn't matter since you can see the list of member variables & functions on the side bar anyways.

    In C++, the pattern I use is:

    Code:
    class Foo
    {
    public:
        public types (if any: enums, nested classes)
    
        constructors
        destructor
        accessors
        public methods
    
        public variables (if any, rare)
    
    protected:
        protected constructor (if any)
        protected methods
    
        protected variables (if any, rare)
    
    private:
        friend declarations (if any)
    
        private types (if any: enums, nested classes)
    
        private constructor (if any)
        private methods
    
        private variables
    };
    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}
