I have a problem related to this:

Are there guidelines on how many parameters a function should accept?

In my case, I have a function that describes a rounded rectangle. The caller specifies

An integer which determines how the rectangle should be merged into previously created shapes
An Anchor, which is a point that is used for alignment (right, left, top, bottom etc). (0,-1) means that position (next parameter) describes the top, middle point of the rectangle.
The position of the rectangle
Width and height
Corner radius

Should I use Parameter Object pattern in this case? It is hard to see how these parameters are related

I have been programming for many years but I am still not comfortable with the concept of "Interfaces". I try to use interfaces but many times I don't see a mandatory use for it. I think this is probably because the projects weren't so big, or because interfaces are more useful when teamwork is involved… >>> More

helper functions as static functions or procedural functions?

as seen on Stack Overflow - Search for 'Stack Overflow'
i wonder if one should create a helper function in a class as a static function or just have it declared as a procedural function? i tend to think that a static helper function is the right way to go cause then i can see what kind of helper function it is eg.

I'm looking at a member function int funct(int x) const; And I'm wondering if static int funct(int x); would be better. If a member function doesn't use any of the member variables should it be static. Are there any things that would discourage this? >>> More
