    global functions and OO


    I never want to have any global functions, instead I always try to put them somewhere..

    Im unsure if I should put global functions inside namespace, struct or class (as static functions).

    For instance:
    Lets say I have int my_random() function, that returns random number.

    Should I put it inside a namespace or struct/class?

    I noticed most of OO programers would do:

    namespace various {
      int my_random() { }
    So what is the best approach?

    From a design standpoint, it doesn't make sense to add a method to a class that doesn't have anything to do with that particular class. So yes, I would say the best approach is to add that function to a namespace with other various utilities, if you're really that concerned about it.

    I would put such free functions inside a suitable namespace, since that is what namespaces are for.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
